if there is a significant amount of blow by, by my headers, its quite loud and there is a lot of exhaust getting through, could that make my car run really badly, like i have no power at all what so ever. i just want to know how much back pressure they need to run properly


thanks, kyle

 

Exhaust leaks make you car run like ****, sound like ****, and can give you serious carbon monoxide poisoning that can kill you.
