well if i do run with kooks, what brand y pipe would you recommend?

 

Jet Hot, Hooker, & Pace Setter headers are fine but the quality leaves a lot to be desired. slp is simply a terrible design (I had a set on my 01 SS for 3 months). They are hard to install & hang down way too low, not to mention the simply do not make the power of the other LT's out there. I have run 2 sets of FLP's & they are very solid headers. I was lucky & only had the floorboard issue on my 1st set, 2nd set no problems. But the best design hands down is the Grott design that PPC, QTP, & Kooks have. After talking to each of those companies I went with PPC. QTP's & Kooks are not coated & there are some that think that is fine but for underhood temps I want my headers to be coated. I'm not even taking the chance of burning up wires etc. Plus the coated looks better too. Also Kooks doesn't have a y-pipe that clears double diamond SFC's & when I called it was impossible to get any answers, to say the least I was not impressed by the service I received. Barry at QTP was very cool, but I'm just not comfortable having un-coated headers. When I called Gordon at PPC he answered all my questions & was glad to talk, which was a big plus to me. If you check out PPC, they are very high quality headers in the Grott design. Mine should be here in the next 2 weeks or so. But go with PPC, QTP, or Kooks if you want the best quality & performance. My vote goes for PPC though.....

 

SunsetWS6,what is the problem that made you not want FLPs again or keep them whatever?

Do you know if the FLPs clear DD SFCs?

PPCs are about $300 more than FLPs.I was lookin into those or FLPs and I'm gettin DD SFCs?

I really like the OR & Cat "Y" interchangablity of FLPs being a Cali res.

You think the PPCs w/catted "Y" is going to top the FLP w/ the OR pipes installed?

well, i looked into kooks and that whole website is just too confusing to me. and i agree with sunset its not coated. i looked into ppc but it is grip. and i had my choices down to slp and jet hot. the reason i wanted to run with slp is because its a complete set and its not too shabby of a price, and also ive seen numbers posted on them. decent numbers as well. and also jet hots are always being voted as a good header..thanks

 

#7 I've been happy with my FLP's, but the opportunity came up to get new headers so I wanted to get the best period. I'm installing a TR 224/224-112 cam & my friend is buying my FLP's so I decided to get new LT's. The Grott design will make more hp especially the more modifications you do. FLP's will not clear DD SFC's without modification. Luckily for me I had a guy who installed mine who developed the prototype drivers side y-pipe piece that fits DD SFC's. FLP never got it right but on my car I have the only production piece that worked so I've had no problems. You will have to cut your SFC's or get a custom piece made if you want it to work. The PPC will clear DD SFC's. Gordon test fitted them on slp SFC's which are the same as KBDD. I paid $1240 shipped for my PPC's. I'm getting the race style headers with an 3.5 collector to 3" offroad y-pipe. You get what you pay for though & they are a quality header. I do believe that PPC will make more hp than FLP's especially the more mods you do to the car. Don't get me wrong though, FLP's are a very solid choice, I've been pleased with mine & they do make very nice power.

 

SLP's are not the greatest header on the market.I saw 2 dyno sheets from the same car,one with SLP and one with QTP's.Same car,same mods the car with QTP's dynoed 10 hp higher than the SLP.Both had ORY's also.

 

Any of the Grot design headers are good, but there is still no need to coat 304 SS except for look. You can over come that by a little polishing with a buffer wheel. All my thoughts about Jet hot are hearsay from this board and LS1.com. I've read to many posts about them hitting everything for me to want them.

 

Mine don't hit anything.

 

The guy who made the prototype told me that the piece can be purchased from FLP. Any truth to that ?

 

Yes & no. I initially ordered the piece from FLP & it didn't fit. So yes they do have his piece but they didn't copy it right so it doesn't fit. I'm happy I bought the piece from Ralph before he retired.

 

Forgive my ignorance. What does PPC stamd for and where are they out of. As far as SFC problems with DD's, would I have a similiar problem with stock SFC"S in my 02 vert.?

 

PPC stands for Proven Performance Concepts. It's based out of Mass I think. You have to be careful when buying headers for a convert, not all of them work.

 

Thanks, I am slowly hearing that alot of suspension and extra goodies e.g. need to be bouhgt in relation to the vert status.

 

My car has dynoed close to 10hp different depending on the day it was tested . Most all mid and longtube headers on the market pic up the same track gains and that is what counts.

 

heh, I got my SLP headers, ypipe, cats, O2 extensions, gaskets and new header bolts for less than the cost of Kooks & QTP headers alone.

Look in the right places and you can save big $$$.

Stainless steel & ceramic coated. I bought them for the quality, not their advertised BS hp/tq gains. Longtubes will all give around the same power gains, give or take 2-5rwhp--- not exactly buslengths distance in a race, all cars react to mods differently.

Ground clearance isn't as bad as people think, but I wouldn't recommend them for daily drivers. Install wasn't much of a problem if you know the shortcuts.

I WILL be switching mine out when I install my new engine because I plan to lower the car, but I've never had a problem with the SLP headers.

As far as dyno results on the same day with different headers... your point? I've seen 25 rwhp difference on my car between back to back runs.
