get a test pipe and when its time for smog, put the stock cat back on.

do not gut your stock cat. the stock cat is very expensive from dealership.

 

Test Pipe It Up!

 

This!

I picked up 16whp from just a testpipe, that was the only change, so worth it...

 

I believe it, we had a customer @ AWD Motorsports pick up a ton of power with just a test pipe upgrade and a tune.

Thanks!

I have intake single 3" exhaust and a 3" testpipe, and my car isnt really all that loud... It does pop and shoot fire though =)

 

test pipe all the way!! I love all my vehicles catless

 

I say test pipe,depends on the exhaust you have it shouldn't be too loud

 

Any updates?

 

I lasted two weeks on a test pipe and just switched to the MILSPEC 100 cell cat pipe. My commute includes stop and go driving and I couldn't stomach the stench at the traffic lights. The noise difference is negligible and the power difference is slight.

 

Hi,

Anyone using the T1R High Flow cat, care to give some review on this HFC. Thank you.
