if your gonna get headers, do not get shorties. get longtubes. you will probably pick up about 15-20 more hp with LT's over shorties. They are a biotch to install, but it is supposedly worth it (i havent dont it yet.) If you get longtubes you will have to get a new midpipe, or cut yours up to make it fit. Some good longtubes are slp, bassani, hooker, and kooks. all these except for slp can be left in when changing a clutch. i believe flowtechs can be left in while changing out the clutch too, and are less expensive then the ones i named. if you dont mind taking out the passenger side header then you can go with mac, or bbk or something. get longtubes though. you will not be sorry
