lol you got it......top down and ripping first and second is ridiculously fun.....especially under soem of the bridges around here....I made one guy do a complete 180 after driving under a bridge I saw him in the mirror standing still looking

made like 3 cars in the last week try to race me only to hear the car and not try....its funny because little do they know its a little m20 with no muffler....I guess its intimidating that I'm burning extra fuel and sound mean as hell or at least it smells like it

I love the way mine sounds unbolted after the cat. But I was wondering if the cat being stopped up would make my car act like it is?

Can unbolting my exhaust from th cat back make a difference on how it runs? It sputters out and loses throttle. I have 88 325i. It sounds so good with it unbolted but if it is gonna make it have problems im gonna bolt it back up.

it may lose some back-pressure, however it shouldnt really make and particular difference in terms of performance, though it may run hotter. having less restriction on the exhaust actually can boost performance. if its sputtering, and losing power, it sounds like you have other problems.
