Cutting these cats out today, anyone know what kind they are?

 

No, do not recognize them. Are you sure they are cats? I have seen a few race shops make square mufflers for drag strip cars. They may be using them inline as resonators.

FWIW, it also looks like aluminized steel with mild steel welding wire. A combination that is truly hard to digest as a fabricator. My guess is someone just took it to a local muffler shop and they threw on whatever they had to quiet it down. Which implies other mods were done too. Have you inspected the entire system yet?

 

It looks to be in pretty bad shape anyway. Why not install a new stainless exhaust system?

 

Those look like they were made in somebody's garage.

 

Just an example of a race shop built muffler that looks similar:

 

Wow... they look very similar.

 

Or a really good used one. I think there's someone here selling an excellent system.

 

Jesus, those are ugly.

 

Those are spin-techs from DR. Gas in your pic? I used those on my mustang and they sound goooood!! They also make some killer transistions and ovalized tubing.

 

Yeah, ripped both off, running straight pipe now

 

I'm not sure which is worse. Straight pipes offer you nothing and will rob power. Not to mention the federal, state and local violations when your neighbors complain.

 

True that, I live in the Gold Coast (Chicago ), way louder cars than mine!
