I've decided to get new mufflers for my car. I'm looking at Flowmaster 40's as they seem to be the cheapest. What size is the inlet pipe and what side do I need the inlet pipe on? Anyone suggest a different brand? I've seen the flowmasters go pretty cheap on ebay, 20-40 bucks a peice. I'm also looking at replacing the resonator with a Cherry bomb, what are the dimensions for that?
