Most likely the Kooks will make more hp/tq (peak or otherwise), SLPs are not widely known for making great power in many cases.

Also look at the QTPs, very nice headers.

I doubt you'll see a large gain (1200 dollars worth anyway). They do, however, tuck up much better for more ground clearence.

that notion seems to permiate all there products. but with that said i dont think a swap is worth it. just keep the SLP's since you already have them on the car.

I also have SLPs and considered switching to Kooks. (ground clearance problems) I just could not justify spending $1300.00 on a set of headers when I already have one. Just my .02

I bashed my SLPs drag racing last week. It sucks to spend another $1,000+ on something I already paid for. I think Kooks makes a better header and that the added ground clearance will nearly remove the possibility of another problem. Too bad I tell ya.
