Ive been looking to get a true dual exhaust for my TT set up for a while now. I want something diffrent that wont be EXTREMELY loud but will still flow well. while everyone agrees that dual 3" is over kill and will flow PLENTY for a 600+whp I dont think I need that since i plan to produce sub 600whp numbers. 500-550 whp is more than enough for me here in so cal.

So the Greddy EVO TT is a true dual system with resonators and mufflers, and some nice titanium tips. the piping is dual 70MM (~2.75in) so I think it will be more than enough flow for me.

I want to couple this to a set of APS 3.5 in downpipes/testpipes, which I hope are not to raspy, i really hate the rasp.

Well if anyone out there has this exhaust please let me know how you like it and what you think of it.

Thanks!

as i stated on my350, 2.75 inches of flow on true duals is plenty for your horsepower goals, the greddy evo tt is prices a few hundred dollars under the 3 inch from a couple other companies. i was running 13.5 PSI on a y pipe with a Tanabe 3 inch Single. no problems and very fast spool up time.
that was putting down 470 SAE dynojet numbers with a really bad slipping clutch.


i have a few EVO TTs sitting here and would be more than happy to ship you one for a great price...

 

i have greddy evo II with H-pipe...its rather loud!!...and raspy at high rpms like 3500 and up...not sure if the evoTT will sound the same but im sure it will sound relatively similar

 

I have the EVO TT installated on my Z. Deep sound and not too loud, but I have not installed my test pipes yet, so I am still using stock cats.
