Default Where to purchase a cat converter?

Hey guys,
I'm just wondering from those of you that have replaced your converters, where did you purchase them from? How much did it cost? Was it stock? High flow? Universal? Whats the size of the tube and length of a stock converter for a 92 Bonneville Non Supercharged?

Thanks again,
Sellncars

go with a high flow unit, from www.justmagnaflow.com

your piping should be 2.25 but i would check on that because in 92-93 some SE'* had 2.5

I purchased a stock replacement unit on-line for about a hundred bucks, shipped. It came with new studs and a new donut gasket. You'll need a set of ramps and a sawz-all. It takes about an hour.

I agree with 1993 SLE and LakevilleSSEi -go to either www.justmagnaflow.com or ebay (same company) and get a 2.5" high flow unit. I paid $55.74 for one off ebay.
There were more than a couple plus sides to that decision:
#1 -FREE SHIPPING on purchases over $50
#2 -A high flow cat was what I wanted and this was by a trusted name
#3 -I couldn't resist.
