Hi and welcome to the forum. I think I can safely say that any of the aftermarket exhausts will give you more of a rumble some more than others. I set car alarms off.
Depending on where you live a member will let you have a listen to anything you fancy. You can also get a standard back box second hand on here for very little money, most members change them.
Stick a post in the intor section so we can say Hi.
