I need some advice here. I'm in the market for an exhaust for my z. It's an 03 with the greddy twin turbo 18g kit. It has stock exhaust right now (I know I'm loosing a good bit of hp). My last z had the HKS rep exhaust and it was pretty dang loud.. Loud enough to **** my teachers off at school lol. What would you all say is the best exhaust to get that air flowin and gain hp? Not looking for something crazy loud or ricey

 

turbos quiet your exhaust down so you can get that replica exhaust and probably be ok.

 

Motordyne TDX2 or Fast Intentions should fit that bill.

 

^^ what he said ^^

 

The Greddy dual RS or TiC is nice.

 

i like my aam 3inch dp's with dumps, then aps 3' true dual exhaust....might be a lil loud from what it sounds like u want....

 

Sorry hijack thread -

My question is, would the regular TDX 2 suffice or opt for their 3in version which is my current plan

 

What power level are you targeting?

 

What power level are you targeting?

 

Im shooting for 400-450

 

I believe that the standard TDX2 will be fine up to 500 to 600HP.

 

+1. You do not want a full dual 3" system. The Shockwave))) TDX2 will provide the best power curve. And if the turbo allows for test pipes, use the ART pipes for the best sound and performance.

 

so for my future turbo application (wanting about 400-450whp), i wont need the turbo tdx?

 

Correct.

 

Correct. You would actually lose a lot of midrange and upper midrange.

The Turbo TDX full dual 3" exhaust is recommended for 600+ HP.
