Your going to have to modify your SLP exhaust no matter what brand you go with. The y-pipes run further back then where they used to be. A stock y-pipe would regularly run under your oil pan, where as long tubes run the y-pipe behind the transmission. You'll only need to saw-zall a small amount of your cat-back. Also the y-pipes don't interchange between brands, they are made to fit their own brand.
As far as ground clearance is concerened, SLP's are known to hang kind of low even on stock height cars. QTP's tuck up really nice, but no matter what someone can still tell if you have long tubes, because thats just the way it is. The only way you can avoid seeing something like that is to stick to crappy shorties or mid-length headers.
Defenitly invest in good set of header bolts though. Stage 8 or ARP both work very well. And before you dive into a header install yourself, make sure you soak any and all bolts with some kind of penetrator so you don't break any header bolts. Just be gentle, take your time, and have plenty of room underneath the car since LT's get installed from the bottom.
I'm a sales guy over at QTP, so if you have any questions let me know.
