ok, so my factory cat on a 94 transam is rattling (not the heat shield) and i need a good high quality cat. not paying 600 bucks for a new ac/delco, so what are my alternatives??

thanks

 

depending on your states emission laws you can just knock all the junk out from inside of it (cover your nose and mouth with a rag and keep it as far away from your face as possible when doing so) and the slip it right back on....

New GM Cat $600
Aftermarket Cat $ 400
Gutted Cat $0
Working The System... Priceless

 

yeah, but i don't like the smell of the exhaust with a non-functional cat. it's already starting to smell like a 69 big block and i hate that.

 

gotta love that egg smell

 

paid $50 on ebay.

 

I know you were trying to go with the 'priceless' thing, but on a serious note, I've been looking at the Magnaflow cats from Summit - bolt-in ready - for under $200 per side.

 

looks like the magnaflows might be a good product? i don't want anything poorly made that will need to be replaced in a year.

 

Find somebody that's parting out a low-mileage car. Used cats for LT1 vettes run around $50-75, so I'd expect it to be no more than that for an F-body.

 

what brand? details?

$66 shipped. Mine was nice quality and it only cost $20 CASH to have it installed.

 

that one is a 91000 series for the v6. i think i need this for the lt1: http://cgi.ebay.com/ebaymotors/MAGNA...mZ230316530654

 

I was showing an example. Be sure the inlet and outlet sizes work for your setup.

 

This is what i am using

I like it really well

 

I guess what I was quoting was the price for both, being a 97 dual cat owner (even though I don't have cats anymore)
which is roughly 400 total, my bad

 

thanks. i need one that has the same in/out as stock. the stock cat right now is welded to mac y-pipe and bolted to 3" cat back.
