which headers
1) Loudmouth does not have any mufflers. If you go with Headers, you do not want the SLP, it will be very raspy and loud, *especially* if you get an ORYP.
2) The magnaflow will probably be a very good bet to keep, but if you want the tips, you can go to a local muffler shop to get them to fabricate some tips that look like the CME, but I don't think it looks all that great w/o the OEM body kit.
3) True dual is the best way to make HP, but it will be very loud. If you don't care about loudness, get the TSP True Dual system.

4) Do a search for headers, it has been discussed more than anything. QTP/Kooks are the best, but the most money while Pacesetters are the cheapest, but with anything you pay for what you get.
