I have some plans tomorrow....we can do it on Thursday
Thanks bro....
Gonna take some more videos as I feel the exhaust has toned down a bit, or my ears are just used to the sound

i think you need resonators before more mufflers.... arn't resonators made for rasp and mullfers made for tone?... heard it in person though could feel it in my chest like bass sounded strong (I liked that)... minus the rasp and you'll be on the money!...lol no pun intended...

Thats a great setup having a true dual exhaust is the only way to go if you want to maximize performance
im not known on this forum im over on my8thgen and Da.net but i wanted to chime in on this cause i love the true dual exhaust look.
after i listened to the video it does have rasp but i thought wouldn't some of that go away once it has a break in period? you need to take it to a dyno im very curious what whp u gained
this is something i cant wait to do but so expensive

i can feel the gains....honestly....but my buttometer has been known to lie LOL....i will be putting her on the dyno and taking her to a track in the next couple weeks....(waiting for just 2 more mods and am DONE with performance except for the ECU LOL)....
and yes the rasp has toned down....I recently had my girl drive the car by me and it sounded very nice....still has rasp and drone but something I can live with but dont wanna live with it....
as I mentioned couple more days and I should have an updated version....

swoosh. try 2 of these, they sound nice and turn lots of rasp into an "air" sound....like a swoosh-ing if you will...
somewhere between $17-35 a piece. dunno if they have a muffler you would need inlet/outlet design though. worth a shot if you want it done cheaply

you are the first one on acurazine to post lol but acktl has a one piece custom built true dual system starting from the precats and ending with the tips lol along with a supercharger n 3.6 L engine...now that shits LOUD
i love how yours sounds man with the resonator it should be perfect

try a single, larger mid muffler between both pipes, with chambers to slow down the speed of the exhaust gas but with minimum back pressure loss. It will work similar to a ported speaker box that lower the frequency of the sound exiting the ports and in turn, eliminating rasp. A straight flow exhaust will be louder because the gasses are exiting quicker, just slow it down with the a custom mid muffler. Its like "H" pipes on the muscle cars to equalize pressure. You also have to bare in mind the power to weight ratio for the setup.
Oh, and I forgot to say that Im impressed. Its because of people like you, that make the sacrifice to go over the top and lay the grounds for others to learn from.

On onto the topic....i had 2-3 setups in mind and since you know what you are talking about here it is....
1> H-pipe: if you see my setups it is:
PCD's -- X merge + muffler -- mufflers -- tips
I was thinking of putting an H pipe upfront so it would be
PCD's -- H-pipe -- X merge + muffler -- mufflers -- tips
I thought this would equalize the pressure before the merge, so it can flow better + prolly tone it down a bit (reduce rasp + drone)
2> H-pipe: somewhere in the middle....so the setup would be:
PCD's -- X merge + muffler -- H-pipe -- mufflers -- tips
I know it sounds crazy but I thought this would work.....Adding your idea to this 2nd point, if I add a straight throw muffler in the middle (I was thinking 2") this would speed up the exhaust flow and muffle the rasp + get rid of the drone....
3> Adding a borla Venturi....suggestion came from another knowledgeable member on the forums....
This would go before the X merge + muffler....
Now the only problem is deciding which route to take LOL....
yeah I would guess....

Thats a good thought and it wont cost too much but in order for an "H" pipe do make a difference, there will need to be about 1 1/2 to 2 feet between the two primary pipes, where the "H" would be and you have about 6"-8" of space between the pipes, so i dont know how it will work for you. Also bare in mind that the temperature of the gases greatly affects the rate of flow. The point after the 2 flex pipes, where the first muffler is will be the hottest part of the exhaust system (aft of the PCD's). I would remover that first muffler and place a larger muffler further back (under the rear seats area) and thermal wrapping as much of the pipes as you can. The hotter the exhaust gases the more pressure builds up in the pipes, causing the gases to expel faster through the pipes.

What.. too much on the video request
@Swoosh. I'm not at all knowledgable in exhuast flow and everyone here as well as yourself is, but can't you copy the H-pipe setup the old 5.0 Mustangs used to use or do some of these ideas already suggest that? Obviously not the same mufflers but just the simple design.

I have seen some threads where people post "Thank" some people and dont thank some people....I am one of those "non-thanked" people and I go like "bishh didnt thank me" LOL....in my thread i made sure no one is disappointed LOL

So if I understand what you saying is remove the muffler with the x-crossover and move it behind ? Dont you think that will sounds weird as the primary pipes wont merge for a long length....Also the muffler I got was the biggest they had for 2.25".....i am thinking of dynomax.....it has a 20" long muffler as compared to 14" which I got....this should help.....
Also, you think 1 muffler is sufficient right ? I really dont wanna go with 2 mufflers....Also what do you think about the pipes not being the same length before they merge...you think thats ok ?

If I can just swap out the muffler and be done with it, I would rather do that....But then again lets see how it goes....I do wanna try the borla venturi and then switch the mufflers....the power am making is awesome....just trying to tweak the sound....

Makes a ton of sense....its the same reason why I ceramic coated the PCD's inside out...To make the exhaust pulses move faster....

the difference between the pipes before the merge would affect the way the engine runs, if the gases between the pipes arrive sooner or later, they may interfere with the exhaust pulses from the next firing order of the cylinder, it all has to do with back pressure. You already have the 2 rear mufflers and by removing the x-crossover and adding a 3rd muffler at the location I mentioned would quiet it down. 2 1/4 diameter piping would have also made a difference, since you dont have any cats on the system, 2 1/4 piping would have been fine (2 1/2 requires more displacement/combustion to mover the air out the exhaust fast enough). Removing the x-brace would provide the room you need to correct the difference in pipe length before the merge collector and give good enough ground clearance. You will surely need even length pipes before any collector of any kind, if not your engine will never perform right and that defeats the purpose of doing the dual setup. Oh and putting the 20" further back would do the deal. A part of me is not sure if the difference in piping length is as much of a big deal on the 3rd gen because where the PCDs bolt up is sort of a collector to begin with and that would basically affect the exhaust pulses as well. These damn 3rd gens are a pain in the ass, I would fix the rasp/droan first, then diagnose any negative affects of the piping lenght differences.
I would like if you guys returned the favor as well

Swoosh, I spoke to a few friends today (older) that have been around cars for a while and they came up with a common consensus. Let me first say this, I know there are a hundred ideas on which setup to go with, not trying to make it more confusing for you. I just wanted to offer a suggestion since my buddies are pretty knowledgable (mostly with Muscle cars) but maybe this will make sense. So here's the setup dicussed today:
PCD to Jpipe to H-pipe, A Res on both pipes after H section, Mufflers,Tips. Obviously you will have the exit pipe after the pair of resonators before the mufflers. But this setup gets rid of the X-merge and equalizes the pressure and as far as I can tell a Res on each pipe won't slow up the exhuast gas too much AND should get rid of the rasp.
Like I said not sure, just wanted to give another idea which made sense to me. Good Luck with the tweaking and I hope you find the right setup SOON.

^^^ Thanks bro....
I have seen those setups before, but never seen an X-pipe....04accordcpe had post some pix up of the same setup you mentioned....I know an Xpipe flows better than an H....lets see where this goes....will post some video's tonight of the current setup with WOT....

What matters is that you find the right setup for you! Doesn't matter what anyone else thinks.

Warning to all...
Guys,
If you're looking to bump up your thread count or looking for extra "Thanks", that kind of thing will not be allowed.
If you want to discuss the topic of this thread-fine.
If you want to "Post Whore" or "Thank Whore"....that won't happen anymore.

So I was on vacation where there is no such thing as internet lol (Adirondacks), but did you guys ever run each other? Wish you had legit slips, I ran 15.357@92.47 stock, and 15.027@94.80 with the rv6v3 j-pipe, and want to see if the true dual price is worth the gains. Just curious. I have to listen to the clips again when I find my headphones, laptop speakers just dont do it.

I haven't seen the X-pipe setup either, but it seems to me the idea I talked about today would flow nice (no need for xtra mufflers) and take care of rasp with the pair of rezy's.

1> Hpipe with 2 4" 22 long resonators
2> Xpipe merge with 2 4" 22 long resonators
3> Xpipe built into a muffler
I thought option 3 would save me some weight....I knew it would be the loudest but didnt know about the rasp....I got a new longer muffler with the Xpipe built in...lets see how that will work out....

Nope cudnt race Justn but did race a VW GTI with Stage 1 tune. He said he was putting down around ~ 250whp and around the same torque....We ran from 50mph - 110mph and I took him by 1/2 car length....when i shifted from 2nd to 3rd (5AT) i was kinda close to the redline and the car took a slight second to shift, else I would have had him by a car length for sure....
I didnt think it was that bad actually. It was humid as hell both times I went, and this is stock full weight 5AT my wheelchair in the trunk, and 18" rimzz. Technically I shouldn't be modding it at all, as I bought it for a daily. lol

Had the same thing happen when I was playing with my buddy in his 07 Si, except he took me... in the manumatic you have to click it at around 6k to get it to shift without hanging there. That is pretty impressive still tho.

Thanks justn....you have come a long way as well....and I wish I had taken the route you have taken....performance before looks....the TL by itself looks sexy but by modding it first you made it sexily quick

I think your Xpipe placement is fine. Honestly, using an Xpipe PLUS an Hpipe might sound strange. I don't know enough about TD exhaust to really say, but I'd imagine there is only 1 'crossover' for a reason.
You could just get 2 of these:
http://vibrantperformance.com/catalo...roducts_id=289
The larger Xpipe crossover seems like a good idea, but upon second glance, I don't think that would fully rid you of your drone/rasp. It will definitely diminish it, but I'm not sure if it will totally eliminate it. I just don't think an extra 6" of sound deadening material will get the job done. You could implement an H instead of X, but it won't flow as well. I'd say you just stick 2 straight through resonators on it.
EDIT: Ahhh, as I was writing this, I see you have made your decision already! I didn't realize the Dynomax was not only longer, but wider/taller as well. It's actually MUCH larger than your current X merge (a little over 57% larger), so it should probably work really well! Let us know how it goes!!

The larger Xpipe crossover seems like a good idea, but upon second glance, I don't think that would fully rid you of your drone/rasp.

^^^ Yes, I decided to go against the H and X pipe....I know the X pipe flows better and want to stick to it....
The reason I went with the Dynomax is coz:
1> its 57% bigger....so the setup will be toned down....I had the magnaflow which had a volume of 4x9x14 = 504...the dynomax has a volume of 4.5x9.75x20=877....if I would have gone with 2 4" 18 long resonators, they would have a volume of (2 quantity x 2 x PIE(3.14) x 1.8 x 1.8 (rxr) x 15.5 ) which is 630-650ish....which is closer to what I have now....
2> 3" internal core....the x merge in the muffler is a 3" pipe....so at the merge the gases will flow better....I know I cant put the muffler wayyy to behind as the gases will slow down at the merge....
I am thinking about moving the current setup behind....as in replace the current muffler and move it behind by 6-9 inches...

if you check the pix my primary pipes are kinda too small....want them to be a little longer....
i checked richie's setup and he doesnt have the mid muffler until almost the rear seats....
why do you think against it ?

^^^ to each his own....I bet according to you adding a sub to the TL is worthless as well since ur doing the diet thingie...according to me driving a TL with no airbags/stereo/seats is stupid...it's a front wheel drive car for crying out loud....but as I said to each his own

Hey man. I hope that your new setup will work for you but if not I still say you should try something like this. I understand budget and labor are two big factors but if all else fails. It just seems like it would flow nice and with two res's it should sound nice too!
Just my thoughts.
