Well jeeves...when you get the headers...and have no converter...with whatever mufflers...it sounds like epic dog sh1t.

Here, let me show you.

Stock Mufflers: 2004 Grand Prix GTP Gayness
Flowmaster Mufflers: GTP Awfulness
Flowmaster Mufflers WITH headers: Craptastic Sounds From Your Tailpipe
Another Awesome one...no cat, no resonator...stockers: RACEFAILPIPES

And if you think ANY of those cars sound good...bye bye.
