cat converter 2.2 4.3 swap

I am needing a new cat converter for my zr2 and seen a 2.2 cat tha almost looks identical to mine. does anyone know if the are the same lenght because everything else seems to match. also how the hell am i going to get these bolts loose there a bitch?

Easier just to buy a Catco ($80.00 at summit) with the proper size. Use a sawsall to cut everything off, and stainless band clamps to put the new one on.

will the clamps hold up for a long time?

also when you buy a universal it does not have a spot for the o2 sensor will it through codes if not hooked up mine has one before and after the cat

on more thing is the stock pipe size 2.25 thanks for the help guys

will the clamps hold up for a long time?

I've been running band clamps for 2 years on my current truck, grappler's been running them for 7... No probs! And they're still shiny!

wher can i get these things not sure i know exactly what your talking about. Ive seen regular exhaust clams.

I got mine through advance autoparts for 8 bux I believe...They are also available at summitracing.com

Here is a pic of my Catco universal cat with the band clamp connected to my original y-pipe. As you can see in these pics, the clamp actually molds itself to shape..And believe me, these puppies can crank down hard.

alright think i have got it all figured out found universal catco cat for 35 bucks on ebay. going to use the band clamps found those also and stick it in there still don't know about this o2 sensor behind it unpluged it to see if it turns dummy light on and it did'nt i dunno but the gut that sells the cat sells 02 bungs he calls them that i guess you just weld in so i think i will go for it. Thank a lot for the help really apriciate it saves money and is way easier than screwing with those bolts thanks again
