Cal from Gruppe-S sold me a Helix titanium test pipe and I wanted to give it a try hearing from people that test pipes give substantial gains....so I went ahead and installed it......and DAMN!!!!!!....thats all I can say...

PROS:
-YOU CAN HONESTLY FEEL A DIFFERENCE!!!
-There's so much more power and its more consistent!
-Sounds meaner too!!!
- dyno gave me 21 hp increase!!! from 302 to 323whp

CONS:
-REALLY LOUD....knowing it was titanium, the metal density is lower and so the sound is even emphasized.....actually not THAT loud but noticeable difference...
- I hate the SMELL in the start but dissipating now..
- RISK of getting caught with it....

so with that said...I will post my dyno numbers tommorow and pics of my STUPH!!!!but yeah if you want some serious power gain for cheap but RISKY....get a test pipe!!!

What I had on my car:
works P2 flash, tanabe downpipe, Espelir Exhaust, Apexi intake, greddy upper i/c pipe.......

 

Holy crap 20 horse. I just order a B&B test pipe to finish off my B&B turboback. I have the stock cat right now so if I can even get 10 horse I'll be happy

 

Can you install just a test pipe without a full exhaust system? I'm pretty new to that part of modding a car so I'm not even sure about it.

 

My car must be a freak as I put on a 3" DP & cat delete on my car and didn't feel a damn thing . I have a full 3" TB now and I don't think it's any faster than it was stock....

 

^^^^^^^^^^^^^^^
Unplug your battery and then hook it back up again.

 

Been there, done that. Let it idle for 15 minutes after reconnecting too.

 

Then maybe your car isn't optimally tuned then, IDK.

 

I have a hallow cat and I can say that its freaking loud especially with my 3071 turbo. The car hummmsss and vibrates all neighbors houses but what can I do?? It gave me 300 RPM better spool and over 20 WHP as well.

 

20 whp sounds abt right. the beauty of Turbocharged car.

 

yeah its really important you get the car flashed or tuned or else you wont feel a damn difference.....

 

test pipe the only way to go

 

test pipe is a straight pipe?

 

yes it a straight pipe.
