so i recently replaced my testpipe with a pdm catyltic converter. everything bolted up nice and pretty sure its not leaking. but now it smells exactly like the rotten egg smell of a bad cat converter. is there anything else that would cause this smell or does this thing just suck ass? this a sohc with intake/header/exhaust btw. thanks for your help

drive it around for a while, usually new exhaust stuff will make weird smells as the stuff thats in them heat up...

should be fine after a little driving

Did you install fresh gaskets?

its actually been on for about 2 weeks, and yes fresh gaskets. im just confused as to why it smells exactly like my 15 year old cat when i first got the car. people have said they didnt pass emissions with the pdm cat, im geussin its just a pos. would anything else cause the rotten egg smell tho?

Unburned fuel kinda has that smell too. You sure you dont have any exhaust leaks?? With the engine running, put your hand around all the connections and feel for leaks.
