Question on using walker exhaust pipes for duals
I found replacement exhaust pipe for 3rd gen foodies that are made by dynomax. Part # 289-47638 Seems to be pipe that would be long enough to go from H pipe all the way over the axle .
The pipe is only 2.5” doesn’t bother me because I want to use two of these for duals on a stock ls1 fbody.
The question is will both of these pipes fit under 4th gen and over the axle (with aftermarket suspension) ?
thanks

Complete kits and then buying replacement mufflers is a pricey way to go. In addition your are very limited with muffler selection because of the positioning and size.
You are right that buying a premade duals kit and replacing mufflers would be simpler, but adds to cost of project.
Two exhaust pipes, relocation bar, mufflers, H pipe is still cheaper than buying hooker duals in my case and then cost of mufflers. Or it maybe same to get it done by a pro.
I’m trying to do a custom build for 2 main reasons:
- Pipe size of 3” vs 2.5” may make difference between exhaust scraping since my car is lowered 1.25” on bmr springs. I got to do some research on how well hooker duals with 2.5” pipes fit on a lowered car.
- Premade kits come with X pipe, I want to use H pipe, but I’m Open to change in plans.
