Muffler Buzz
I've decided to chuck most of the exhaust from the header-back and I don't know what to replace the parts with. I'm not looking for horsepower gains (the auto-trans probably couldn't handle much more), but perhaps better economy, a MILD note, and no loss of torque.
*Should I have a local shop make a system back to the muffler, or order one pre-made.
*Can I keep the existing CAT? The check-engine light hasn't come on, so the O2 sensors and CAT seem to be working fine (except for the raw-fuel smell at idle).
*What muffler? I had a GreddyEvo on a '99 Civic Si and found it to be a little too loud. Is there one that's recommended that has a mild sound/note?
*Lastly, of course I'd like it be "inexpensive" but not "cheap" if you know what I mean.
Thanks in advance for any help!

1. I would get a premade one ordered for best results.
2. I leave the stock cat. Since you aren't looking for any gains, keep the cat and save your money and the environment.
3. If you want a mild exhaust note, get a Greddy SP2 or the Apexi WS. They look and sound almost stock but with some HP gains.
4. Keep the cat, get a DC sports ceramic header, and a nice sounding premade exhaust. Won't cost more than $800 if you find good prices on those two items. I would also remove all the heat shields too.
