I am having difficulty finding components to put an exhaust system on my 89 Firebird with a big block. I have the Hooker SuperComp big block headers and I would like to use the Mufflex 4-inch CAT back system but I can't locate a Y-pipe to join my headers to the CAT back. Any ideas?

 

I think I just answered my own question. Mufflex makes a Y-pipe for Hooker long tube headers that have two 3" couples to the headers and then mates up to their 4" single system. I'll bet anything we can fab the last few inches to mate to my headers. It can be seen at http://www.mufflex-performance.com//...ducts\new.html Pretty slick stuff!

 

Glad we could be of some help.
