Had my catalytic converter stolen a while ago and the stealer wanted something like $1500 for a new one so I went with an aftermarket brand. Ever since then my exhaust fuems stink. Can't drive with the rear window down anymore because of the horrible smell.

Is there a better brand of catalytic converter??

 

I had mines stolen a while back as well. I installed a magnaflow cat with no problems.

Are you sure not running rich or burning oil/coolant (causes a horrible smell)?

 

Thats kinda how not factory cats work.... They let those fumes through, ive gotten used to mine.

 

don't think I'm burning oil or coolant? I'll look into this magnaflow cat.
Thanks
