"Fucking launch that AWD shit."
"We got AWD we'll rip you out of the whole, bitch."
"AWD is tits."
The most commonly found aftermarket cat-back exhaust system found on motor vehicles, especially domestic trucks and suv's. Generally popular for their relatively affordable price, large tip diameter, and loudass sound, they are one of the best selling exhaust systems to date. Although restrictive in design, most people think that the vehicles whom are equipped with such product is faster because they are fucking dumbshits when really it just chambers the exhuast flow to attain a certain frequency of sound that is relatively annoying and increases interior resonance. If you would like to be original with the sound of your car, don't buy a flowmaster. Flowmaster comes in several models, all of which suck my ass.
Dumbass: "hey did you hear that truck with the flows on it, it was fucking sick."
Me: "Fuck Flowmaster, they can kiss my ass."
