Hey Guys my truck started to sound like a boat when going through deep puddles the last time it was out.

Crawled underneath and the cat was just rusting away. Do not have a lot experience with exhaust systems but it looked like an easy swap except for some nasty looking bolts.

I pulled the cat last weekend ( required the sawsall) and ordered a replacement via the local parts house. The cat that in came was much smaller and weighed a lot less than the one taken out. Also, it was missing flanges on the ends to reattach with. The guy at the auto parts place said to cut the flanges off the muffler pipes then use couplers to reconnect. It looked to me like some welding would be needed so did not take the part.

Is there replacement cat that does not cost 200 dollars? Was the guy pulling my let about reinstalling the muffler using couplers.

Thanks for your help,
