Alright so... in the morning, I was set on the Greddy Evo2. After watching EVERY SINGLE YouTube video, I've decided its too loud for me. Then I saw this post (https://acurazine.com/forums/showpos...postcount=1309).

Now, hacking up the stock setup isn't something I want to do so I think I'm just gonna go full custom. This is what I'm thinking... please feel free to make ANY suggestions: (red items are things I already own)

Jshift precat deletes -flange-> Jshift Jpipe -flange-> Jshift test pipe -flange-> 2.5" ID SS pipe -weld-> Dynomax 2.5" resonator (WLK-24215) -weld-> 2.5" ID SS pipe -weld-> Ypipe 2.5" single inlet, 2.25" dual outlet -weld-> 2.25" ID SS pipe -weld-> 2x universal mufflers.

What do you guys think? All piping will be mandrel bent. Comments/suggestions regarding pipe sizing and brand of components are welcome. For metallurgy, sticking with SS because aluminum is crap for Chicago.

My list for universal mufflers: (prices from Excelerate)
Vibrant TPV Ti tips $170


Vibrant TPV $140


Tanabe Medallion $204-240


HKS Universal Stainless Hi-Power Ti Muffler $230-250


Skunk2 Universal Muffler $135


MagnaFlow Universal Muffler with Tips - Street Series $130-140


MagnaFlow Universal Muffler with Tips - Race Series $140


There were a couple others but oh well.

Any suggestions for the Ypipe?

Thanks in advance guys.

 

That won't be as loud as Greddy but not as quiet as you want. I'd say stick with the stock 14" resonator instead of the 12" one if you're worried about sound, maybe even larger.

 

first off, sell the test pipe, you really don't need it

I would do the following

precat deletes -> jpipe -> custom

and I would definitely not use vibrant, not the best sounding, either do the hks, skunk2 or tanabe

look up my video of my skunk2 - youtube.com/stillhere153

as for the resonator, aero 2.5" all the way, dynomax creates drone imo

Damn you fools never SLEEP! Haha

Aight, well, from all the "stage 3" vids I've seen, I'm good with that about of sound.

Regarding the test pipe, if I have it, I might as well keep it. Please, its resonated so why not right?

I really want those Tanabe Medallions but shit, $200-250 for one?? Fuck me! That Skunk2 one is much cheaper. Al, whats your take on Tanabe vs. Skunk2? They seem to be pretty identical.

Can I keep it like this?
Jshift precat deletes -flange-> Jshift Jpipe -flange-> Jshift test pipe -flange-> 2.5" ID SS pipe -weld-> Aero 2.5" resonator -weld-> 2.5" ID SS pipe -weld5"-> Ypipe 2.5" single inlet, 2.2 dual outlet -weld-> 2.25" ID SS pipe -weld-> 2x Tanabe/Skunk2 universal mufflers

What about the Ypipe guys??

 

I kind of feel like you're giving yourself more headaches than you really need...

All these exhaust combo's you've been throwing around are madness, there are several pretty awesome cat backs meant specifically for our cars, and they're SS. Running an after market J-pipe to a 2.25 inch test pipe back to a 2.5 inch pipe and resonator doesn't really make sense.

What sort of tone and look are you looking for?

 

Jpipe and test pipe are both 2.5"...

Don't really know exactly how to describe how I want it to sound. No drone for sure... check these out:

Do the universal mufflers change the exhaust note? In the last vid, the guys got flowmasters and it sounds sick.

 

option 4 is best... IMO, Me well im gettin this done soon maybe pre cats but
Jshift JPipe -> Jshift Test Pipe -> Custom -> Magnaflow

 

Ehh honestly I'm not feelin any of those exhausts the tanabe and the last magnaflow only ones that looks decent without looking gawdy and ricey. I still think you should do the Greddy's

 

Whats option 4?

I really like the Tanabes. Bforbrian has those on his car before the ATLPs. The Greddy setup with the Aero resonator is gonna run me about $1000 including labor. This custom setup will definitely be less than that. I can use the money saved for my next mod

I like the Magnaflows too. Any difference on the shape on the muffler? Round vs oval?

 

Word I hear that. Yeah I remember seein those tanabe's on his car they look good.

 

to be honest I loved my old skunk2 custom catback, I only got rid of it when I got the greddy evo2....


check out some pics of my buddy DJ KHALID .... skunk2 canisters on an NBP



pm me if you need a price deal on the skunk2 I have a connect for yah

 

Yeah that shit looks good. Do you have any experience with Tanabe? If they are similar enough, I'd go with the cheaper ones (Skunk2). PM sent.

What was your set up like? Was the EvoII still louder?

 

just go straight pipe from the headers back, thats what im doing haha
personally, i dont think it sounds bad at all

 

I'd say use the test pipe since you have it and regarding being ok with the stage 3 sound, replacing your mufflers and adding larger piping will make it alot louder and more droney. I think most of the exhausts made for the TL's are 2.5 from the car that go to 2.25" from the y pipe to the mufflers, IIRC.

 

Is that stage 4? Too loud for me.

Thats exactly the setup I'm going for. I did my research

 

OK so... if I go with the Skunk2 cans...

Skunk2 mufflers + Aero resonator + Y pipe + piping + labor = ~$750
Greddy Evo2 + Aero resonator + labor = ~$1000

I think I'm gonna go with the first set up... hopefully I can order everything tomorrow and receive every by the end of the week. I'm gonna try to get this in by Sunday...

 

OK I need AZs help yet again.

To get a quote from shops, I need an estimate on the length of pipe I'll need. Please keep in mind that I'll be using a 14" resonator so take that out of your estimate.

Thanks

 

im not too sure if its considered stage 4 or what
i just put it on there because i think it sounds good haha
its not too loud but it has some tone to it
i have a sound clip but it does no justice at all
in the beggininng it sounds like a damn ricer but i will post it anyway to give you a little idea
[IMG][/IMG]

 

Hmm... from what I've read, no mid muffler and resonator = stage 4 but I might be wrong.

Sounds decent... I want a lower growl though.

 

yeah i hear yah, i was just throwing that out there
i dont know all the stages and i was just reading the thread about it the other day haha
and yeah, everyone has their own taste and ive never heard the ATLP or anything else really in person but id like to!

 

Yeah I don't have the option of driving 10 mins to some dudes house to listen to his new ATLP or Greddy or whatever exhaust like those bastards in CA or the tri-state area Makes me angry... and very jealous

 

haha i bet man
not many people around me have ATLP
a few in charlotte are fixed up a little, like accurratien (eric) haha
and a few others on here, i cant remember their names tho

 

:troutslap
Fixed up a little? Haha

Anyway, resonator comes tomorrow ... dunno about the mufflers yet!

 

Hey guys I need some help:
No one in IL mandrel bends 304 SS... only aluminized steel, which isn't ideal for the amount of snow (and salt) our cars experience (one shop owner said an aluminized steel exhaust will last 3 years!!).

I made some calls yesterday and this is what I have to work with:
1. mandrel bent aluminized steel, MIG
2. mandrel bent aluminized steel, TIG
3. pre-mandrel bent 304 SS, MIG
4. pre-mandrel bent 304 SS, TIG
5. pressure bent 304 SS, MIG
6. pressure bent 304 SS, TIG

Ok so out of those options, I'd rather go with option #4. Also, one of the shops that mandrel bends their aluminized steel can spray the pipes with a rust inhibitor, which should prolong the life of the metal. Another option they have is to powdercoat the pipes with a substance that acts like a rust inhibitor and also dissipates heat better.

Some final questions:
- Now, I've done my research and I know mandrel bending is the way to go because you can maintain an almost-consistent cross sectional area throughout the bends. Obviously, pressure bending isn't recommended but how much of a difference will this make with my setup/car?
- Another question I have is regarding the welds. If I go with the pieced together 304 SS pipe sections, I'll have many more welds than I'd like. Aside from aesthetics, each weld introduces a new stress concentration. With the salt/weather and the altered material properties in the heat affected zones in the base metal, what kind of life expectancy should I expect to see from these TIG welded pipes? Lets assume best case scenario... very experienced welder, no bottoming out etc.

Thanks,
Jason

 

Where did everyone go??
