I agree here, and please god dont take the cats out if you do any kind of performance muffler. Ask Greg how his car sounded with the Mac mufflers and I want to say it had a Mac Prochamber...sounded like straight ass. My friend has 40s with no cats and it sounds ok at low rpms and idle, but geeezus christmas it sounds like poop under high rpms, or hard acceleration
