do you think ill get better gains from the slp than i will against the kooks or jet hotts.

 

Kooks seem to be having the best gains, followed by SLP and Jethot. As for quality, you pay for what you get. The Kooks are the top of the line T-304 Stainless custom built headers. They are not coated, but 304 dosen't need to be coated. They ran me $989 to my door for a stepped stainless set. Headers only. SLP was my second choice cause they fit good, but if your car is lowered, they aren't the way to go cause they hang kinda low. SLP is also T-409 Stainless with ceamic coating. The off road headers are around $775. Headers only. Jet hots are more for the do it yourselfer. You'll likley have to grind and cut in places to get them to fit right, and they are mild steel w/ ceramic coating. I've heard a few good stories about them, but almost everyone has had to do something to get them to fit right. I think they run for around $475 for a set. Headers only. I wanted something that I knew was going to fit, and also netted the biggest gains in HP, so I went with Kooks. My choices were followed by SLP, then Hooker, and I prolly would have never even thought about the Jet-hots due to the stories.

 

My Jet-Hots have been just fine.

 

Out of those three...Kooks.

The Grot design headers (Kooks, QTP, Thunder...) produce the best gains from everything I've seen/read.

 

Guys...don't rule out the new equal lenth stainless steel and the best clearence "QTP's"...they are the best IMO...but I do like my FLP's...I'm gonna sell mine soon and pick up a set...as for SLP...nice but very bad clearence issue's.

 

well i was really set on slp longtubes cuz ive seen more numbers with them than i have any other. if i do get kooks would i be good using a y-pipe or am i good to go and just get some hi flow cats along with my loudmouth...

 

we have tested every header out there for the ls1 on the chasis dyno except for the QTPs and by far KOOKs and Dynatechs make the most power gains Ls1s really seem to like stepped headers

SLP seem to be the worst

 

really...well what does the dyno #'s say with kooks vs. slp. and if i do get kooks do all i need is maybe hi flow cat with my loudmouth. or do i stil need a y-pipe or x-pipe? im not getting qtp anymore. just seen how long people have waited for their product. but anyways chef, what were the stats?

 

AF, the stock Y isn't going to bolt up to LTs...so you're gonna have to buy one or have one made...or an X, if you want to go the true-dual route.

Do you really want cats? Because an off-road Y would be a LOT cheaper.

 

i am curious... how much horsepower is the difference? i am not seeing the point of spending 400 bucks more on headers for 10 lousy horsepower. I was under the impression the most u could get out of headers was about 35-40 and in most cases it is about 30. Maybe i am wrong. Anyway i have heard NOTHING bad about jethot headers. I dunno where Beast96Z got that info, but that is news to me. Infact i would like also to hear more about that since my next purchase was gonna be jet hots!

 

well i pretty much narrowed my choices down to slp, or jet-hots. between those i would like the slp cuz their set with a y pipe with cats and ive seen numbers with those headers compared to jet-hots. but jet hots seem to be decent. but if i run with jet hots will i still get good gains with just a cat and no need for a y pipe?

 

Th word on the street is that Jet-Hot is due to release a catted y-pipe for their headers in the very near future.

 

yeah ive seen that on their post. but ill tell you what though bout slp. ive emailed people whove had them and they say when it comes to clearance issues that its not as bad as people think. and its not bad *** flp bangin the floorboard. but im looking into jet or slp. i would like jet hot if im on a budget. but when i get back from this deployment ill have enough to get the full exhaust set up...what do you guys think. but if i do go jet hot it will save a little bit more and i can get my lid, ftra, maf. but i just like the idea of combing both slp products thats the loudmouth and headers.

 

Why are you not considering the Kooks anymore? They're better than both the Jet-Hot and SLP, IMO. They're a little more expensive but you get what you pay for.

SLP would be last on my list (by far). Ground clearance may not be that bad...but it ain't good. I've heard they're a PITA to install (at least compared to other headers) and the design...more bends does not equal more flow (tuned headers: ).

I'm not sure what you're talking about when you say, no need for a y-pipe? You do need a Y-pipe with LTs, the SLPs (FLP and TTS) just happen to come with one. If it doesn't come with a Y (like all other LTs), then you need to get one.


The Grot design headers have had the least complaints (I haven't seen any) so that's what I went with (QTP)...but it's your money so buy whatever one's you think are the best.

 

I have seen two sets of SLP's, and it looked like you could carry 2x4's between the collectors and the floor.
