The only excuse for a exhaust is if you are in fact running something mad under the bonnet and even then a sleeper is much cooler and will turn more heads than a chav wagon. That being said good wheels are nice, make it clean and I like the look of my leather interior. If it's poverty spec then electric windows makes it look better when you want to shout romantic comments at woman walking down the street. Oh and also make it lower, not stupid low but close some of that arch gap. Arch gap is like a pussy, the more fingers you can fit in the worse it is.
