slp LTs not make good power
some people say they dont make power! i would like to see a side by side header comparison of the slp and kooks, qtp, and others. i think on gmhtp on a gto the slp headers put down i think 50 hp!! they even had a dyno chart. i wish gmhtp did a side by side header comparison like they did with a lid. i think slp designed those headers like that for a reason too.. but i also read that it does hang more low than others so it doesnt hit the floorboard, something that the other brand headers i guess were doing.
It is a longtube....and makes decent power compared to the rest of the brands out there. But the fitment sucks, and they hang as previously stated.
Several brands are better and cheaper

I have SLP's on my 00' SS VERT.
I do not understand everyone commenting about them hanging low. I have Pacesetter Lt's on the LT1 car, and they sit lower.
Both cars have the same suspension setup (Sportlines) and the vert is heavier and should be a bit lower, yet it does not scrape half as much.
Maybe its a difference between the LT1 and LS1 design, but I don't think they hang that low.
As far as power, I think they are within 1-3 rwhp of Hooker, Pacesetter and all the other 1.75 inch/3 inch collector LT's out there. Not worth it to buy SLP's new, but sometimes you can find them for a steal used.

No. That is completely un-true. The only thing is that on a lowered vehicle they start to interfere with ground clearance. Having owned a set, and only sold it because it was flanged and fit perfectly up to my hooker catback and ORY...I just didnt want to separate the 2.
