i have heard those are pretty good, give you some power and still keep it leagel, plus they are cheaper than a new one!!!

Hey guys,

After some extensive research I finally found a high performance catalytic converter that more than likely will fit perfect with my truck. If anyone else has a 93 318 4X4 setup here you go:

;)good research

Last time I checked out ebay there were a few cats that were about 100$ shipped too. The add said it was 'High Flow' which is what im guessing you want. I believe the brand was Catco which I've heard was good.

i bought 2 today, magnaflow cats $98 each.
