High flow cat ?

[Chevalier]

the reason it blow up was due to the rings. they seized up and such, it was a 83 chevy 305 that ran strong til the rings seized up. An automatic with true dual just exhast tubbing from the manifold back.

Ever watch drag racing?I don't know about you but I have never seen a top fuel dragster or funnycar have cats hanging off their headers.For that fact never seen cats on anything going down the quarter mile.So the no cat=engine damage seems bunk to me.Back to the subject.High flow cats are basically straight pipes anyway.A small version of a cherry bomb.That's why the check engine light will stay on,cause the high flow cat doesn't do anything compared to the stock.
