Test Pipe Legality Question

RE: Test Pipe Legality Question
Short answer: yes. Long answer: no.
It really depends if your state does emissions testing. The gains are negligible for an OEM cat vs. Aftermarket High-Flow Cat vs. Test Pipe so it's really not worth it.

well they do but since its just on a flange i plan to take it off when i have to.....My friend did the same and he gained about 5hp at high rpm but lost at low due to of course backpressure. And it sounds amazing
