2.25 exhaust?

[skykrawler]

I have the 350, I am looking to put a new dual exhaust. but I am being told I can only go 2.25 all the way back. is that true?

if it's stock, 2.25" is what you want. if you've got high flowing intake, heads, and a larger cam, you'll want to step up in size a little. exhaust pipe too large will slow the velocity of your exhaust down to the point that it might ruin your engines ability to scavenge properly. ive got dual 2.25" on mine.

2x.... this is what I would have done if I would have done my exhaust right the first time. run 2.25 full with a balance tube (h-pipe) and dual mufflers. You'll get better backpressure and better lowend torque.

I had 2.5 on my 305, and it sounded great, but now that I have a 383 it just sounds mean.

But 2.25 is what I would put on a 350 unless you have the mods stated above.
