SLP Headers. Are they reallly that bad? I just got into the GM LS1 world. I have always been a Ford guy and have owned 4 Mustangs. I just purchased an '02 Trans Am WS6. I am looking to add full exhaust to the car. I found a set of SLP LTs and Y for a descent deal. I was looking to get them but did a little research on here. Kooks seem to be the preference here. Does SLP not make a good LT? I have always thought SLP was respected. They have to be better than MAC and Pacesetter. Any help would be appreciated. I am looking to get sommething by next week.

i've used them, i got a pretty good performance gain from them (26 rwhp), but the ground clearance SUCKED... i swiched to a set of headers that were Hooker style.

i think most people's complaints about SLP long tubes is clearance. they hang pretty low under the car. there are a lot of good LT's out now for LS1's. just depends on what kinda money you want to spend and if you want noncoated, coated, or stainless.

Clearence does seem to be the issue after more studying. Thanks guys. I think I am going to look at Kooks. Looking for a good product that will last forever.

Kook challenged me to remove my SLP long tubes and put a set of his prototypes on and guaranteed me 30+ RWHP OVER the SLP's - I did and they did.
Amazing.
He even said he would give them up for free if they didn't. I think they made 31 on the dyno.

Whoa...This is highly incorrect. SLP's are equal length long tube headers. Your trying to say they don't make power? Unbelieveable what people say. They make a handful of power just like the majority of longtubes on the market. Basically what you are saying is that your Kooks headers made 65-70rwhp alone????
Not that I don't like the kooks headers because they are extremely nice and function equally. However, I can 100% guarantee that is not the case powerwise. Even from Mustang Dyno to DynoJet. Maybe if you had a 600+ CID BBC motor, but you don't. Even then far fetched. Just because you are hinting at SLP sucking doesnt mean they do. They have one of the largest research facilities out of all the aftermarket companies for our cars.I challenge you to have the car dyno'd next time you decide to do an imaginary pull in your head for what you think you are actually obtaining powerwise.
All I am saying is don't post ignorance on here and expect everyone to believe it. What you've just said is one of the most insanely idiotic things I've ever heard. At no point in your rambling, incoherent response was there anything that could even remotely be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

Yeah and my hi-performance blinker fluid is on back order, and my flux-compasator is in the shop; or I would have 600+ RWHP!

I forgot how some people communicate on this board. I was a Member of LS1.com for many years with many thousands of posts (if that matters)
Despite the intermediate rudeness, I will direct my comments to the thread originator.
Mikey from RapidMotorsports did the install and comparitive testing from the SLP's to the Kooks and may remember all of the various specifics.
Not that the specifics will have any bearing on some who just like to cease what was intended to be helpful and turn it into a sophomoric exercise in ignorance.
The final net gain was 31 rwhp. The increase over the SLP's was considerable enough to surprise both myself (who has built many cars, most of which before many of the members were out of diapers) and an experienced engine builder in Mikey Klemen.
Again, this is going back 5+ years but if the SLP's had made 12-15 hp the Kooks made 31. In fairness to the SLP's... they were installed first and the Kooks after much more was done to the motor.
The clearance was much better on the Kooks and the design aspects for creating exhaust gas accelleration and scavenging was obvious.
The Kooks stayed and the SLP's were given away.
My intent is to answer the question of someone trying to make a decision for a car we all supposedly share a respect for - Not spar or trade personal attacks.

Well if clearance is something your looking for stay away from SLPs they hang to damn low. The reason i got mine was because i bought them with a 3" x pipe and magnaflow mufflers for an incredible price. Yes now i can't lower my car but oh well i can't do anything about it, other than buy a new set of headers. And im not that much into lowering my car to go fork up more cash on headers. But yes SLP headers are bad clearance wise.
