wich exhaust do u guys think is the best and that will have less back preasure and at the same time not so loud? Right now i have a Fijitsubo exhaust and tanabe Y pipe. i will be going with the aps 3.5inch down pipes and after all the research i have done it looks like a tru dual is the way to go

 

Oh snap.

 

from the research I have done... for sound and performance.. it comes down to the APS and the Greddy EVO TT

 

Stock exhaust with a Cherry Bombs in place of stock muffler FTW

 

2inch single exhaust with a cherry pipe IMO

 

No exhaust is the best exhaust.

 

OK, that really helps

 

Cant help yourself by doing research, dont expect others to help you. There is no best exhaust, turbo kit, clutch, etc, etc, every application and owner will need to decide what would work best for them.

 

Greddy evo tt has 2-2.75-inch pipes. not as loud as the aps and aam 3-inch exhausts, but from what i've read from sam at gt motorsports, it has good flow. this is the exhaust i'm going with in my new build. it's really all up to how much noise you are willing to deal with and how much horsepower you want to make.

 

you will have to modify the exhaust to mate up to the larger aps pipes tho.

 

what type of tt do you have, that factors as well and true dual would be the best way to go

 

Soemone said that the Greddy TT would bolt right up to the APS 3' down pipes....

 

My point was this. On FI applications, having no exhaust is the best way to go. Because your turbo/s itself is the bottleneck, not having any exhaust restrictions would be ideal. But everyone knows that. As for my exhaust.. I went with a custom set up from my exhaust guy. Cost me $200 for a true dual 2.5" set up including down pipes. More breathing room than my car will ever need. The only down side to this is these pipes are heavy bastards! Oh well.. I can live. No spare and a smaller battery probably made up for the extra weight. Oh, and my car is LOUD LOUD LOOOOOUUUUDDDD! But that's not really a downside to me

 

It will bolt up to the big APS pipes. The bolt holes are the at the same location. I would recommend trying to 'easing' the transition from the 3" outlet on the pipes to the smaller 2.25" inlet of the Greddy exhaust. The greddy TT exhaust tapers down where it bolts up to the cat/test pipes and a .5-.75" jump could hinder flow.

They will bolt up without issue, but just something to think about

 

GReddy EVO TT FTW! Run it on my G35....
