If you can afford a TT kit, the you shouldnt even think of doing it without the proper exhaust, its vital on a turbo car, especially a high compression motor that wasnt designed for the high EGT that Turbos generate.

If you cant do it properly, then save longer and do the job right.

 

Hold on, it's not so bad for a TT setup, Tuan/GRD tuned me to 442whp@9psi with the Nismo exhaust on my G. He thought it flowed very well. But it does rasp more than I like.

 

+1.....same design just larger pipes and tighter fit......no pun intended.

 

Craig, it should fit. The tips on the EVOTT are the same size as that on the EVO2 and it fit fine with my stock bumper.

 

Perhaps you didn't read my post. The kit was DESIGNED for the stock exhaust, if you add a less-restrictive exhaust you are flirting with destroying the engine. My point is, the stock exhaust IS the proper exhaust for the PE TT kit at "stage 1". In fact, I was pushing safety having TP's and a NISMO on it. I quickly took off the TPs and went to stock cats, and the point was the TPs caused RASP.

Not everyone who improves the performance of the 350Z goes the maximum hp off the bat. After seeing APS, Turbonetics, etc, blow engines in 3K miles or less, I think my plan of heeding the manufacturers warnings and increasing hp safely worked. I'm over 60K miles on a stock block, and it's a daily driver. And I've enjoyed the increased power for over a year and a half, without dropping huge money from the get-go. So I'll let the experts with one or more blown motors do their thing, and I'll do mine.

 

The nismo flows very well for what it is. The midpipe is huge.

Back to the OPs issue, I think the Xpipe on my new exhaust is the rasp eliminator, as my setup does not have testpipes or resonators in front of the xpipe, it is one piece on each side util the Xpipe. The Xpipe ends just after the frame crossmember. Of course I can't prove a negative, but it appears the Xpipe is the solution. As for a H pipe, just don't have experience with one. My thought would be to try it first as sold, then experiment if needed.

 

tons of picts *cough* search *cough* ;-)

I think its more for a NA car, i got a buddy with that on his 600+ z, looks good but very restrictive, comapred to getting a custom exhaust

 

I am sorry but who is Ron?

 

That's me.

 

I currently have a custom HKS Single outlet exhaust with a 2.5" Y Pipe to a single 3" pipe going to a HKS C/F Ti Canister with 2.5" Test Pipes. Plenty of rasp.

I know the EVO TT will rasp less than my current setup. but will it still be pretty bad especialy with the APS 3.5in Downpipes?

 

The EVO TT has the H pipe in basically the same place as the SVRtech custom 2.5" has the xpipe, according to the pictures Cheston has on of it on his thread.

 

the only thing i dont like about the evoTT piping is that the pipes adjoining the cats actually go down to a 50mm :\

 

WHAT? That is a big diffrence that makes me not want to get it anymore

 

Hmm, Is that more or less than the APS 2.5"?

 

50mm is less than 2", so it is less than the APS 2.5"

 

Ok, I wasn't sure if it tapered down or not.

 

Guess I am going to have to get the SVR Tech TD 3". Now i just need to source time Ti Tips.

Hey Zivman, where should I buy the APS 3.5in Down Pipes

 

The SVRT setup comes with 3" down pipes already

 

its comes with 3" TESTPIPES the APS 3.5" pipes go from the turbo all the way down, thats why I call them Down pipes, It would be better if the SVR didnt include the testpipes for me
