Go get one of the cheap-o ebay hi-flow cats off ebay. Its like $25. From what I understand, SC doent require car inspections right?!... Ive been thinking of regestering my car to SC for that reason, so a high flow is your cheapest rout.
i prefer something that is quieter. i rode around for a year with no cat at all. advanced auto parts has a magnaflow oem style cat for $50 but i won't get as much performance.
just get one from online. kids are always putting in test pipes. you wont find a difference between a cat or test pipe power wise. it's a myth. unless you have built engine and 3 inch exhaust.
Yeah, there are differences though. Ebay 'hi-flow cats' usually are just a resonator that goes where your cat is, to reduce resonance and get rid of that twangy sound you get with no cat. Random Technologies or Magnaflow cats actually have a catalyst, but the honeycomb is much less tight as OE cats.
