here is the problem, I really want 3 inch but my down pipe is too small only 2.25( I think)

Does anyone have a cat or test pipe that goes from 2.25 to 3 inch??

Or should i just get 2.5 inch exhaust??

No one is running the Tdo5 greddy kit with a 3 inch??

I have the New GReddy Power Extreme 2
ITs a 70mm. so its between 2.5 and 3...

Get a 2.5" exhaust with an exhaust cut out on your down pipe so you can run open down pipe at the track or whenever you deem necessary
3" will be loud

Is there really gonna be a big difference between 2.5 and 3 inch?? In loudness?

falcongsr

running 2.5" downpipe and 3" exhaust here. pretty happy with it. not sure if a 2.5" would be a big difference in power.

How loud is at at like 3.5k rpm cruising?? like ear ringing?

falcongsr

3.5k...that would be about...60mph in 5th gear. its not bad at all. not ear ringing.

on my tranny its 80mph in 5th gear

The Thermal stealth isn't as loud as the regualr thermal, I dno't know by how much, but I heard it's a good tone that isn't overbearing.

Hell, I run a 2.25 exhuast and it's loud. But my wastegate is louder than both.

for boost 3" is a must



homemade custom evoeone style 3" all the way with dynomax, yes,

falcongsr

i think everyone here who has a 2.5" downpipe had it made at a shop.
