I am currently running just a 2.5" downpipe on my car(the Mule), and it's wayy too loud. sounds like a friggin transport truck. I have a cat lying around, and I was wondering if I could just put that on there to quiet it down. pros? cons? Does it make the exhaust smell bad and can it get clogged with soot? (my car smokes A LOT). is a cat more restrictive than a muffler? thanks
yes, it will quiet it down.
yes, it will make it smell bad.
yes, it will get clogged with soot if your car smokes THAT much.
yes, a cat is WAY more restrictive than a muffler.
sell that cat for a few bucks, and buy a real muffler.
