Ok guys, I want to replace my exhaust muffler but I don't want one that is too loud. I definitely want the added horse power but not the noise it comes with. I also don't want to spend a ridiculous amount of money on it. Any suggestions? It is for an E30 M3.
I heard that was pretty good. Right now I have a "fireball" looking exhaust. I have no idea what brand it is. There is a cap at the exhaust that restricts the hole to about 1 1/2" to 2" in size. I've been trying to remove that cap since it seems like it is removable but to no luck. I think its stuck. You think that restriction causes a lot of power loss?
