Im looking into get the omni power test pipe for my Si and I was just wondering if anyone has experience with them. How is the quality? Do I need to get the pipe welded since it has adjustable clocking? And how was the power gain on the butt dyno? Thanks.

 

adjustible clocking?

I make my own test pipe, there no real reason to get a test pipe unless if your turbo and dont need back pressure, other then that use a cat.

 

I just bought a carsound high flow cat for 55 shipped.

Don't pollute yo

 

Cuz im gonna start road racing starting summer and I want to run catless on the track.

 

Why? Just do open header if you dont want backpressure but thats not going to help because you want a little back pressure unless if your fully built.

 

velocity....not backpressure backpressure is never good

 

Open header is too loud for me lol. But yeah..i think im gonna try out the test pipe..prolly get it in a few weeks..getting my car back from the shop tomorrow..finally.
