Budget Mod: Blast Pipes.

Blast pipes are a style of exhaust back box/muffler, also known as a shotgun exhaust. Blast pipes are a straight through design, angled and often pro-trude further than the bumper. Suffice to say running blast pipes is not for the faint hearted. Blast pipes can be bought off the shelf, for example the "Greddy DD system or "Aspec Blast Pipes" These exhausts will give you the look and build quality but at a price, because blast pipes are such a simple design they can be made by hand if you have the use of a welder.
