exhaust system

[84_GT350]

As long as you keep the system at a reasonable size (no bigger than 2 1/2") you should be ok on a stock motor. You might lose a tiny bit of low end torque but it will be made up with the future mods you're planning. You're right about the back to front planning....that's how I'd have done it if I hadn't needed an entire exhaust system in a hurry. Get the mufflers and H-pipe at once. You'll want 2 1/2" mufflers, which won't fit on a stock 2 1/4" H-pipe. On the flipside, if you get a 2 1/2" H-pipe, the stock 2 1/4" mufflers won't work.
