I still have the mufflers and tips from my current car, Brian. You'll need to figure out a system (or build one) but you can have those. Loud, but not as loud as the typical bazooka. I'm simply changing my mufflers out for something a little quieter. The tips are welded on..
And I have enough scraps of pipe we can probably cobble together a system for yours, especially if you have an engine that's out of the car. Makes life so much easier..
And just saw your G-down post; yes, I've done that with my buggy and current car. I didn't use the G-down though, simply modified a set of bazooka's, though the G-down has the advantage of having the exhaust port mounts already turned. If they have those in an unpainted steel, you'll be way ahead of the game.
