hello, i am installing my APS ST this weekend coming up and i was wondering if i would still be able to use my injen straight tip exhaust?
i also have helix test pipes. please if any1 knows, tell me if i am going to be able to use this setup

Also i have the full street tilton clutch + flywheel. i think that it only holds up to 300 hp?? (correct me if im wrong) what do you guys think would be a good replacment for it
thnx for whatever help you guys can give!

the helix test pipes get replaced with the downpipe that comes in the kit. and to use the exhaust you would have to have a reverse y-pipe made.

 

Eric,
We need to put a stock exhaust back on until you can get a good 3" single exhaust for it.

 

Zcargarage just did a G35 APS TT with the Injen exhaust, they were worried it wasn't going to make enough power because of the small piping on the exhaust. Well it made 470whp and like 430Trq. Did pretty well. If you have the exhaust you should try it.

 

Thats correct, however he is installing a Single turbo "ST" and it eliminates the cats and "Y" pipe.

 

Injen exhaust will not work unless you do some modifying like replacing the dual pipes to a single pipe connecting from the downpipe.
In theory though wouldnt one side of the injen exhaust work with the ST? lol

 

Ahh, I see. Good luck.

Freak'n double posts

 

I am much in the same boat as you. Looking for a new clutch for my aps setup. I am considering the ACT and RPS at this point.

In terms of exhaust, I would go with the APS exhaust for the ST. I am considering switching to the aps TT exhaust for my setup as my tuner thinks my greddy might be a bit restrictive for my hp goal. It is killing me because I love the greddy.

 

there are several exhausts out there that are just as good or better than the APS exhaust for less money. a single 3" will suffice. the APS splits right before the rear wheels, its not really a "true" dual exhaust.

 

Which APS exhaust isnt a true dual with twin pipes all the way through?

 

A single 3 inch exhaust system would be sufficent with a high flow muffler though the APS TD system (true dual from the 3.5 inch mid pipe) will have superior gas flow to any single 3 inch exhaust system, (particularly at higher boost pressure) hope that helps.

My APS "TD" is getting installed on my APS ST on monday, ill keep you posted on the results.

 

That would be kind of small. The pipes on the Injen are 2.25" each.
