Looking for some advice on what to buy, everything I have on the car is MAC, but I dont think they sell individual cats.

Magnaflow maybe?

Also, is it possible to weld stainless cats onto a steel h-pipe?


Thanks.

As far as I know, all cats have a stainless housing, but I'm not 100% sure.

An older Mac catalog of mine has individual cats in it, I heard somewhere that they're actually made by Carsound (same place that makes them for Magnaflow). The cats on my x-pipe are Magnaflow and they seem to do well.

Yeah, why the need for cats. I put cats on my o/r pipe last march and had to get them hollowed out three weeks ago cause they melted down.

If it's a passing emissions thing, I'm sure you can find someone to pass you without cats.

A catted H-pipe will have slightly more torque on the bottom end, which some of us like for a street-driven car. Also, after a while it gets old smelling like gasoline every time you drive your car (this may not be as a big of a problem with a mild cam, but I can't remember...). That's why I usually run cats for daily driving. Get longtubes and it's trivial to swap the midpipe.

Wow thanks! I'm assuming no air means no smog pump, and w/ air means there is a conncetion for the smog pump to feed into?

Thanks.

No problem, the air no air IMO has to do with the presence of a smog pump. But to know for sure I suggest that you call the MAC tech line to verify. Good luck!
