Does anyone know what MTM/Hoppen does to the stock Exhaust Manifold and Catalytic Converter for their Stage III Kit?

Thanks

Perhaps MTM/Hoppen will tell you if you ask them.

I did email them. Will call if nobody posts with information. -- PC

the manifold is ported in certain areas to help flow and the end of the cat is modified so the outlet is 3", therefore mating directly to the 3" downpipe

Yes, A4 here. That certainly was objective enough. I appreciate your quick response. Is there anyone here in the Springs area with this kit, or maybe just a MTM/hoppen stage II?

I bet it's beautiful in Florida now. I used to live in Gainesville. I seem to remember stuff was blooming like crazy around now.

Colorado Springs is still really brown and dry.
