I read, I searched.. I have a lot of info already thanks too many acurazine users who have taken the time to summarize all the details on the different exhaust stages..I appreciate that!

Now, specifically talking about Stage 3 which is removing stock resonator and mid muffler and replacing with a Dynomax resonator and completing the piping..

Im about to do this also..

But there are many Dynomax resonators being recommended.

Pulled the specs from Dynomax page..

1. 24215 is a 12" in length and inlet/outlet size of 2.5"
2. 24234 is a 12" in length and inlet/outlet size of 2.25"
3. 24235 is a 18" in lenght and inlet/outlet size of 2.25"

Don't know the stock oem exhaust size on the 08 Base TL but 2.5 and 2.25 seem to fit based on all the mods performed with the Stage 3, but has there been any actual comparos between different Stage 3 setups with the variations of resonators?

I don't believe there is a comparison video for all of the different tones that come from the different race bullet mufflers. I installed the 24235 on my Base '04 TL. I like the way it sounds. Here is the link to how my car sounds now. Keep in mind that the exhaust tone in the video sounds much louder on video than it does when you are physically standing behind the car.


I have been debating whether I should swap in the 2.25'' round 12 inch bodied Dynomax race bullet muffler, but I think I will live with the 24235 for a while since it was about $60.

The 24215 is the typical resonator used in the stage 3 mod. The TL has 2.25" exhaust piping, so the 24215 fits over with a lot of extra room. I had this resonator on my car at first BUT I also have the RV6 V3 jpipe and it caused some rasp in the 3k range. So if you're ever thinking of adding a jpipe that removes the 3rd cat, you will get rasp.

I now have the 24235 on my car and there is 0 rasp and no drone at any speed. My advice would to be to go with the 24235. Check in Undying Dreams and Ebelp's progress threads, they both have videos of what a stock TL/TL-S sounds like with the stage 3 mod done with 24235 resonator. I also have videos in my progress thread with the 24235.

Thanks both for your replies. I have no additional plans for exhaust, I just wanted to change the tone a bit. I did order the typically recommended 24215. It arrived today so I will probably install next weekend.

Jordy, your videos were some of the ones I looked thru when searching, thanks for posting them.

The Machine, I'll check your thread now. Youre feedback makes me understand I am good by sticking with the 24215 since I have no future plans with the exhaust.

I'll try to post some vids once installed.

I'll probably be doing this mod in the spring, but I wanted to see if anybody had any input on how far downstream the resonator placement affects sound. For example, if I place the resonator closer to the third cat or right before the muffler split. I would *think* it could have some impact on cabin drone, but then again I could be wrong. Anybody have any thoughts?

EL BAN

Im not sure it would have some type of effect, would the velocity of the exhaust flow change?

I got the Resonator today, I was thinking of placing in the exact same position of the OEM one with the added pipe replacing the Mid Muffler in order to be able to replace everything back in in case I want to return it to stock form..

But I would like to hear feedback also on your question.. Thanks or looking..

Still not sure when I will install.. I need it to be done quickly cause my backup car blew the engine.. and my muffler guy is full of work.. I know this should be a straight forward work for any muffler shop but I want it done cleanely in case I need to revert back..

ultimatum127

I had a mid muffler delete with a straight pipe and a resonator delete with a Dynomax Resonator put in, unfortunately i do not know the model number of it, and frankly im a bit lazy right now to go to my car and check the receipt but i will later! My exhaust sounds amazing though, a little hollow at below 2K RPM but from 2-4 its deep then 4-5 it loses its grunt but past 5 the thing sings. I currently have a video on youtube under ultimatum127 and our free to look it up if you want a comparison, keep in mind though i filmed it with my phone(galaxy s3) and it went to high for the microphone.

zachlone

I currently have a stage 1 setup, if i want to eventually swap out the J pipe with XLR8 V2 which removes 3rd CAT should I not do the stage 3 if I want no rasp??

EL BAN

From the feedback provided by the guys here apparently you will get rasp if you have stage 3 and add more changes to the exhaust..

I got mine installed today.. sounds lovely.. as expected.. from 2k-4.5k is has a nice grunt under load.. nothing too extreme and at cruising speeds in higher gears it is seemless..

Now I need a drop in filter..

From my personal experience if you add a jpipe that removes the 3rd cat and use the Dynomax 24215 resonator it will create some rasp around 3k.

I have the RV6 V3 jpipe, Dynomax 24235 resonator, and mid-muffler delete, and have no rasp whatsoever.

zachlone

If I stick with just a stage 1 and add a jpipe that deletes 3rd cat will it sound good? Deep and smooth sound?

TL Luver

iTrader: (2)

Yes it will sound good; the two front pcd's being deleted is what ultimately is responsible for rasp; requiring 18in magnaflow or dynomax resonator...

zachlone

Ok I'll prolly just hold off on the stage 3 mod and just get a jpipe with my MM delete. That way I get some performance gain

Jordy Spaur

I have been debating whether or not to swap in the Dynomax 24215 in at a later date. I am trying to let the Dynomax 24235 break in before I decide to swap it out. So far I have put about 400 miles on my car since I put in the 24235. The tone has gotten a bit more deep and pronounced, but it isn't as loud as I want it. Obviously, the whole point of the "staged" exhaust modifications is to make our cars sound more like a G35, or G37. I know it is nearly impossible to make our cars sound like that because we own Acuras and NOT Infinity's, therefore our cars aren't Infinity's so they will never sound exactly like them. But I want to get as close as I possibly can. I figure that the 12 inch Dynomax 24215 would give me more volume, but I don't want the rasp. I don't plan on getting a J Pipe, so I know that if I decide to upgrade to the 24215 that the "rasp" issue won't be as bad. Anyone already have the 24215 installed in their Acura with no other mods (ex. J-Pipe) and like it?

EL BAN

Thats what I had installed. The 24215 with no other change. I love the sound. It is enough but not too much. But each individual will probably be looking for a specific sound level which is hard to be met by just one single setup.

The car at idle only seems a bit louder, if you are just cruising you will hear a tamed growl coming from the exhaust and if you step on it WOT it will sound loader specially between 2k-4.5k after that the engine sounds matches up with the exhaust.

At highway speeds in 4th and 5th gear it is tame, not annoying but you can still hear a light tone over the stock exhaust. I have only put on around 40 miles on it since yesterday so I would expect for it to settle in a bit more after break in.

What made you decide on getting the 24235 rather than the 24125? Anything specific? The main reason I started this topic was because of that reason. Wanted to get feedback on how each setup compares to each other and why were several Resonators were being recommended for this mod. And the posts here cleared that up for me.

zachlone

Ya exactly I don't think I've ever heard the exhaust on a G35 or G37. really all i want is a nice deep sounding exhaust, but not tuner fart can sounding and def no rasp. Just a nice smooth v6 sound. nothing loud but just enough when you step on the gas you hear the exhaust growl. I owned a hemi dodge ram with a 10 series flowmaster dual exhaust so i've had loud before. My bro owns an older acura integra and it just sounds like a loud shitty explosion and thats something I dont want. these cars are luxury, sporty cars, its not a race car by any means. A nice sutle growl would make it more noticable tho. At least thats my

good info thanks

Stage 3 with Dynomax 24235 (everything else stock):


Note: The video doesn't do it any justice, especially since the camera is mounted right above the tailpipes. In the cabin, the exhaust tone is buttery smooth. It roars when you want it to and it's quiet when you want it to be quiet.

EL BAN

Good video.. I will try to get some clips from the bumper and also from inside the cabin..

Bankz

just wondering would you get rasp if you do the stage 3 mod and already have a ATLP V2 jpipe

Bankz

with the 24215 dynomax resonator

The Machine

iTrader: (8)

Bankz, since the j-pipe removes the 3rd cat and if you put the 24215 in you will get some rasp around 3k. If you put any j-pipe on that removes the 3rd cat, go with the longer 24235 resonator. It will sound just as nice and you will have no rasp.

zachlone

the ATLP V2 jpipe doesnt delete the 3rd cat so you should be fine, unless you swapped it out for the race pipe.

Bankz

OK thanks for the info guys

gentlemen, Bankz has been PM'ing me.
he's asking me about the resonator.

his setup DOES not have any rasp.
someone is pushing a dynomax resonator to sell him.

I told him that the dynomax resonator would quiet down his exhaust even more. and that if he bought it, it would be wasting money since his current setup doesnt have any rasp.
do you guise agree!?

Bankz

My setup is atlp v2 jpipe atlp race pipe and stock exhaust, i was looking to do the stage 3 exhaust mod with the 24215 dynomax resonator

justnspace

iTrader: (1)

Ohh! you want to do the stage3 mod!!! ohhhh!!!
this changes things.

and I am unfamiliar with this. gentlemen, please chime in!

Bankz

sorry for not clearing things up for you

justnspace

iTrader: (1)

^no not at all!
just trying to halp!

zachlone

From what people have said in the other threads, the 24215 dynomax resonator with a 3rd cat delete will cause rasp.

zachlone

get the 24235 if you heart desires the stage 3 mod and dont want any rasp

justnspace

iTrader: (1)

bankz, this sounds like solid advice!

zachlone

Do you currently have a ATLP J pipe with race pipe and Mid Muffler delete? or just the J pipe?

justnspace

iTrader: (1)

he has v2 jpipe atlp race pipe and stock exhaust.
he wants to do the stage 3.

Ok, let me not try and eff this up for once, since it's beena trend lately, lol.

Ok, since you DO have the 3rd cat still in with your atlp V2 j-pipe, if you remove the mid-muffler and stock resonator and replace it with the 24215, it will be louder by a pretty good amount. Not anything overbearing, but it will definitely be noticeable.

I have the RV6 V3 j-pipe (deletes the 3rd cat) with the 24235 resonator and love the sound of mine. I would recommend going with the 24235 IF you ever plan on removing the 3rd cat and putting the straight pipe in. IF you remove the 3rd cat and have the 24215 resonator in you will get some rasp.

zachlone

I would suggest that he deletes the MM before changing out the resonator. Do it in steps.

zachlone

He has already deleted the 3rd CAT with a race pipe
