The other day I got a straight pipe welded in place of my resonator. As soon as I drove away I didnt like the sound but also noticed my car was quieter and wasn't as fast. I was hitting 18psi consistently and now I was barely reaching 16psi if even that. I went back and got my resonator put back on and the problem still is there. The car is still the same. I can't figure out what would be causing this issue. Exhuast leak? Bad welds? I'm gonna have a shop look at it this weekend. Car still drives fine but its not the same. My car also sounds stock again its not loud at all. I have a corksport racepipe and corksport axleback and it sounds so quiet when before i touched anything down there it was much louder. Ive also lost the vibrations i got from my exhuast feels like stock again Help anyone please? Sorry for the repost!
