I just bought a Sebring fireball style muffler with a silencer($180can.) and I going to get my exhuast setup pefectly so I want to know if I should take out the resonator and get 2.25' manderal bent piping all the way back to the muffler from the cat. What is the resonator for exactly ? If I remove it, will the chances of failing an emisions test go up ? I read that the G20 exhaust system is " pretty hard to improve on "-SE-R forums, so is all this necessary ? Can I expect any HP gains ? Or should I just leave all the stock piping and weld the muffler on the back ?
