ok, i think im gonna go with a magnaflow muffler(or maybe the aerochamber), and keep the stock resonators there(still getting the new tips). I didnt see on my existing one, do I need a Cat with an air tube? and aboot the O2 sensor, how close is it to the cat? should I get one that has the sensor boss on it already? or will it be after the "coupling" on the cat? also, should i just replace the o2 at the same time? "if it aint broke, dont try to fix it" comes to mind when i say that though.

You do not need a cat with a air tube or O2 boss in the housing. My rear O2 sensor is about 6” from the back of the converter. And don’t replace that rear O2 it’* only purpose on OBD2 cars is to throw a SES light if your converter is not working properly or missing.

good that makes it alot easier.

ok, im going to try and get this done on this paycheck. or at least order part of it. stupid question: is that the muffler right after the cat? or is it the resonator and the mufflers are after the split? i was just assuming that the muffler was the bigger POS behind the cat.

FWIW - You can also get some pre-fabbed items (DP and HF cat) from Hogan Performance. Curt is an awesome guy.

I have to agree with Tommy, I bought a bolt in cat from Curt and he is a great guy to deal with & also has great parts.

that price aint bad at all. i may just get that, id probly pay more for that to be fabbed up at teh local exaust shop. this way, i know it fits. whats that "interlock flex" option?

the resonator is the one right after the cat and your mufflers are at the rear of the car.
on my '00, the mufflers(Aerochamber) were offset in, center out, just like the pic from 2000 SilverBullet'* car.

oh. damn, im glad somebody told me that. i would have gotten the wrong crap. i gotta buy two mufflers. YAY

ok, after researching, i think im gonna go with magnaflow. they are stainless, better price. a few peeps said that dynomax is popular with the GN crowd, but i was looking at the flow numbers for the super turbo dynomax muffler. its not as good as magnaflow or dynomax'* ultra flow(which is more $$$ than magnaflow). im probly gonna go with one of these three:
