2002 Exhaust, what is what???

[tweak89]

So, I've read plenty of threads on exhaust options/mods etc. But I'm still confused as to what part is what. Resonators, rear mufflers, mid mufflers etc. According to the diagram below, 1/2 are the catalytic converters, 3 on back is the muffler. So, when people say resonator, what to they mean? Is the part that is labeled 3 the resonator and the parts with the exhaust tip the muffler?

Catalytic converters are on the far left of the diagram. Resonators are #3 and mufflers at the far right.

Thanks, I thought so, but reading different threads and looking at the Borla system (where they call the middle and rear parts mufflers) was throwing me off.

So I have a question, I live in Montana so emissions law are minimal, so can you put regular headers ( I realize the would have to be custom built) on this car and then run larger exhaust pipes with regular mufflers?

No . Not unless you also installed the O2 sensors in their property locations to their necessarily data to the power train module.

Thanks for the info.

Dump what you have and pick up the high performance Borla exhaust system, front to back (Borla Everything)

I've been debating the Borla system, but may try out new Magnaflow/Flowmaster mufflers first since it's a much less expensive option. I'd hate to cough up $900 to find that I don't like the sound.

I had 18 inch long Magnaflows installed by a custom shop for around $425 and the sound is there when you get on it but quiet just cruising. I have been happy with change.
