I have to dis-agree with you guys. I had a test pipe on my car and it was not that much louder and there was a LOT more low end torque. When I put on the high flow I lost a lot of this gained power.

About the poluting issue. So you guys do realize that all cars 25 years and old do not get emision tested at all. Not to mention that most of those cars stock put out twice as much exhaust as our little 4 cyc cars do.

If there was a way to get a high flow back on my tib trust me, I would have one on it!
