This thing sounds awesome, nice and deep, but no resonance on the highway, easier to hear on downshifts. I don't know how much power I picked up, but it definitely revs better up top. The two things I like best about this exhaust is it was cheap, and no CEL!
I take it back the best thing about this exhaust is the sound.
