Right now I have a greddy ti-c turbo (dual) exhaust. However, I bottomed out and damaged it pretty bad. I took it to a local shop to repair the leak and line it back up. However it sounds like crap now. They said the resonators were damaged and need to be replaced. Does anyone know if I can buy any other 2.75in mid section/resonators to fix the problem? Or would I need to buy the exact same greddy mid section? Any info would be greatly appreciated.
