i tried to search this but didn't come up with much. anyways i was just wondering what catalytic converter would you guys recommend for my 03 cavy? also you guys with cats already did you have to weld them on or did they clamp on. i was also wondering what headers you guys would recommend. thanks

i have a carsound magnaflow cat. no CEL lights here. if its hooked up right then you shouldn't get any cel.

and the Header i have is a pacesetter ceramic coated Header.

is your cat welded on?

There is probably nothing wrong with the one you have. My 04 has a nice cat.

Frank, if Dan is redoing his exhaust, the stock cat is going to be to small on the inlet & out let pipes. Also the stock cat is restrictive, so he'd just be causing a bottle neck at the cat and see no real gains.

I also have the car sound Magnaflow cat. It's sitting in a closet next to my Pacesetter armor coated header. the cat is an OBD2 compliant high flow cat I picked up in a GP from Gravada Tuning. It'll all find it's way onto my car after I fix my suspension.

Anyway, yes you can use clamps to hold the cat in place, but your better off getting it welded on. Clamps really are only ment as a tempory fix untill you can get the right.

I would like to know what the stock cat flows. I have changed them before on GM cars and have seen no change.
