I am going to order a freeflow cat converter from the Jegs mag and I need some specifications on which one to buy. What are the inches for the in/out ends. I have a 92 RS 305 V-8
Thanks

 

Just call summit, they should be able to tell you the exact one you'll need.

 

I have a universal CATCO 3" converter thats supposedly a high flow cat. Looking at the ceramic inside, it doesn't look anyless restrictive than the stock ones. Anyway, it was $60 so yours should be a little cheaper because they are smaller but you need 2 of them. You have to do a little work to make it fit right because the stock cat(s) use flange connections.
