    i think the main reason is that they hang too low compaired to other brands

    Well I can live with that since they were already installed. Was hopeing it was not performance related at all.

    I don't quite get the "over-rated" part of it. I hear that often. Most aftermarket companies 'over-rate' their products to some point.

    Normally longtubes pick up 15RWHP...more with tune.


    I remember SLP making claims of 'up to 60HP' with their longtubes. Talk about a fake out to noob modders.

    wow...Like said many companies over-rate their parts, but 60hp for headers, well that's just stupid.

    Looks like they have pulled that down...


    But this is there now...
    Reduce 1/4-mile ETs by up to 5 tenths of a second and increase trap speeds by as much as 5 mph.

    Wow that pic is impressive on the difference. Kinda too late now, they are on there and hopefully they will be fine. going to spend the cash on heads, cam next.

    They are not bad. Heck I have Mac Mid length that were already on my car and I just went 12.22@112 with a not so good 1.79 60 ft. I just have a custom cam and factory heads that have had a few things done to them. I might change sometime to something different but I am going to get into the 11's with this set up first. Leave em on and go from there.

    I'm guessing they probably based those gains off of a built heads/cam car with......stock manifolds before the long-tubes???

    Medium I guess. 228/236,588/578 114 I was hitting the rev limiter so after a few adjustments it should be better next time. I have an auto with a 3400 stall and a 3.73 12 bolt.

    I would enjoy seeing SLP in bankruptcy and out of this industry. The way they treat customers is unacceptable and this is from 2 very bad personal experiences with them. On top of that, their products are junk performance wise.

    That pic next to the kooks is just funny. lol

    + 1 for bad customer service. I also have had bad experience with the company, they would not even correct a bad molded lid for me that would not seal worth a damn.... a lid it wasnt like they were losing money on a lid.
