The U bend delete will free up your exhaust flow. Removing the resonator is going to give you a raspy V6 sound. Leaving that on and putting a nice set of fufflers on to change the tone will give you the low tone that you are probably looking for. This was said on another thread, but I can't remember by who. I've heard alot of people saying that they like the magnaflow mufflers. But everyone has their own brand that they like. Mine, I hacked off the resonator and mufflers a few years back and she is load as I doon't know what. Mainly did it to tick off the cops back home. Thay liked loud trucks but not cars. Gonna throw some mufflers back on Shortly. Probably some type of turbo muffler for now until I do the full exhaust on her.

If you want loud and good sounding get the Borlas. I think you can get them on Ebay for about $80 each.

Glasspacks are still going to be somewhat on the load side. I had 2 SS muflers on mine at first, glasspack style internals, had a desent tone, but I couldn't sneek up on anybody. It's really on what your looking for. A noticable difference at start up and driving or scare the heck out of little kids at start up and alot louder tone while driving. As for emmisions, glasspacks might put you on the edge of yes or no. But it should be as long as you have a good cat and your rides in good running condition, you might be alright. Don't deal with that much here. Atleast not yet.

The u-bend and resonator have nothing to do with emissions. As long as you weld the O2 sensor back in when you remove the u-bend you'll be fine.

Most muffler shops won't alter anything that touches an emissions device (02 sensor), it might be technically legal, but most don't want the potential hassle from the epa folks.
