3" exhaust

[Ugly1]

Pypes does 3” and they don’t make you have to have cat’s with them at this time. Anything smaller they go with California emissions setups.

They are standard universal mufflers. There is a guy on one of the LS Gbody groups on FB who is running I believe magnaflow mufflers. Just normal offset 3” in/out.

I'll have to take some measurements. The only difference between the Hookers and the Magnaflows is that the Hookers are flared at the ends. I guess I could take them down to the muffler shop and get the ends flared.

I have a Pypes 3" X pipe with RacePros. It's not overly loud.

The fit is moderate but the price reflects it. Expect to do some tweaks. I didn't have to cut anything in the middle but I had to fab my own brackets and dent some spots in the floor.

My complain with the Pypes kit is the exhaust comes out under the bumper instead of behind the rear tires. I had to cut and modify the kit so it dumps behind the tires.

I'll second the Pypes with RacePro's being pretty decent, not overly loud until you open it up. I went with the 2.5" since I'm only running a 403.

I’ve been looking into those as well. Unless I go a little more custom but it won’t be stainless if I do. Having an ElCamino Hooker doesn’t make one that fits.

Yeah, the El Camino makes it rough to put exhaust on, I had a buddy once try to put the Jeg's kit on it, but couldn't make it work without major modification.
