The difference might be between the tunes. Do you know what kind of boos that other tune was running compared to yours? Also do you accept kidneys? lol I wish I could afford this.

The exhaust is a pretty unique design. Regardless of what the wanna be genius' say on the forums, we do what works even though its not what they are used to hearing. The exhaust is dual up front. We hand craft a special resonator that brings the two tubes together into a single 3". Towards the rear, the exhaust is then split again into 2 manifolds (one on each side) and then the quad tips. The reason this is done is so there is quick boost response for good low end power. The changing of diameters is for the purpose of exhaust velocity. If you run large piping throughout, part of the powerband is going to be hurting. We arent working on honda cars here where you get power at a billion rpm, PEAK. A good broad power band is what makes your car faster. |

I bought my car used with this exhaust on it. Does putting this exhaust on force the removal of all stock OEM catalytic converters?
If my car does not fail the visual inspection, will this exhaust guarantee the failure of the emissions test?
