Who makes a 3.5" catalytic convertor?

[GREG O'Brien]

I've tried Dynomax, Random Tech, and Catco websites... but still haven't seen a 3.5" catalytic convertor listed.

I know they are made... who have you guys used?

I have one to sell. It probably wouldn't work in your application though. Rather than being flattened to fit under the car like most cats, it's round. It originally came on my F-350 where space is not such an issue. About 15" long by 8" in diameter with 3.5" inlet and outlet.

thanks, but i am trying to find a high flow aftermarket oval one.... i know they are made - but by whom?

Worse case, buy a 3" and take it to a muffler shop to get modified.

Borla and Random Technology make them.
