Looks good and sounds good. Have you had these pipes on a car for a while? Any issues with passing emissions and/or what kind of feedback are you getting from the test car? I'm asking cause I've seen a lot of vendors produce products and then let their user community really do the testing. Having had one blown engine that way, I might wait to see how they run after a few people have had them on for awhile unless these have been tested or something. Any input?
