Hi all.
i am looking to redo my exhaust, it is rusted in spots and I’d like a little more growl as well as I’m swapping to a notched bumper so it’s time.
i have stock manifolds and want a whole new system. Where is the best place to find/ buy this? I was reading that parts place is no good? I’d like to go 2-1/2 all the way and still not sure about mufflers, contemplating borla ( if anyone has them let me know your thoughts) but that’s up in the air. In a perfect world I’d like to buy the down pipes and tailpipes separate so I can buy the mufflers I want.

if I have to I’ll buy a full set and just not use the stock mufflers

thx in advance

mike

I’m also wondering if I should be adding an x or h pipe and does it really make a difference?

I would go 2.5" and Walker Dynomax Turbos. There must be about a bazillion choices for 2.5" A-body pre-bent pipes, at least for header-back applications. If you plan to run manifolds you'll need to have the down pipes bent to fit.

This is the problem, I’m looking to buy pre made pipes. Someone must make them. I’ve seen a few on eBay and I’m wondering if anyone has used them.

Will down pipes fit both a 350 and 455, I keep seeing ones that say they will fit both

This spring I put Pypes 2.5 stainless exhaust with their mufflers and Thorton’s manifolds, on my 72 350. I went with the X pipe exhaust and their BBO down pipes. I did have to do some bending and cutting to get the fit how I wanted it. Overall a very nice system.

I was looking at that but I don’t have the ability to cut and weld the exhaust
has anyone used the exhaust from inline tube? I think it is all factory stock size, 2-1/4 and 2” after the mufflers

I've used Gardner on another application and can tell you they are fantastic. Not the cheapest by any means, but you will be very happy. I bought the aluminized steel off road option and it sounds great. Scroll down on the sound clip link to find Olds examples.
