FLP or SLP whith do you suggest?
FLP or SLP whith do you suggest? I have an '01 T/A WS-6 (M6) with the following: k+n filter, slp lid, slp bellows, slp 85mm maf, slp 160 t-stat, loudmouth and slp man. fan switches. I was wondering which headers you would recommend FLP or SLP? Everything on my car so far has been SLP so I'm leaning towards those but not if the flp's will give me more power, also is there anything else I should do to maximize the gain from the headders? My father has an '02 ZO-6 and I hate that it makes my car feel slow!

Re: FLP or SLP whith do you suggest? Anouther question: I love the way my loudmouth's sound but I'm afraid it may be a little too loud once I add the headers. Any one have this set up?

Re: FLP or SLP whith do you suggest? Most would say to go with the FLP. But I would say to go with the SLP. That is what I am going to do even though my car is lowered and here's why. You will get a flatter torque curve with the SLP. At low to mid range the SLP make 10-12 more hp than than the FLP. At the upper range the FLP give about 10-12hp more than the SLP. The LS1 kicks in at the upper rev limit. It's weakness is at the lower rpm range. That is why a Mustang GT will keep up with us up to 60mph. After that, the LS1 kicks butt. So the SLP helps to compensate for the weakness of the LS1 while the FLP doesn't do as much for the low and mid-range area. I would say that the FLP and the Mac's are comperable because they are geared to the upper end of the torque curve. Maybe I am wrong. If so let the flames begin.

Re: FLP or SLP whith do you suggest? There is no way that the SLP will make more HP down low than any other header IMHO. They are both great headers, but neither one of them will help you with low end HP. If your car is lowered I would not even consider SLP. Just my $.02

Re: FLP or SLP whith do you suggest? All LT's give about the same gain on a stock engine. Sometimes I laugh when I read what some people post. If you are dead set against any other brand, then get FLP's for a lowered car.
Re: FLP or SLP whith do you suggest? My car isn't lowered now but it may be in the future, would that give me a problem if I went with the SLP's and what kind of gains should I expect with the modifications on my car?

Re: FLP or SLP whith do you suggest? I was just atth Chicao Vettefest at McCormick placein Chicago and got a chance to see and compar these tw headers. All I have to say is: FLP's are a lesser product. Not only are they not stainless steel, smaller Y-pipe compatable, and known for more problems, but they cost more too!
DCV performance is having a sale on SL headers with cats and the install kit for $1200! Versus FLP's $1299. Slp's are a superior product that will potentially make more power. Meaning- if any heade puts out more, the SLP's will. Also, the Y pipe is redesigned and tucks u vey nicely, I saw it firsthand. Good luck.

Re: FLP or SLP whith do you suggest? C'mon guys, all things being equal - all equal length, "tuned" headers are about the same as any other. All of the outragaeous claims by the companies as well as some of the forum posters are a little hard to swallow sometimes. If you have a heads and cam or stroked/bored car then you will see the headers really come alive, they sound nice and add a little power on stock or slightly bolted on cars. As far as I know, the FLP's give you a bit more clearance if you are lowered, the SLP's give you some damn nice quality headers (my SLP's bang the hell outa the floor - the y pipe that is)but I love the workmanship and overall quality. If you buy the SLP's be forewarned they are a pain in the *** to put in but it's do-able. Only my .02 cents of course.

Re: FLP or SLP whith do you suggest? If you haven't done so, you may want to explore your options. All of a sudden a bunch of shops are coming out with LT headers. Thunder, Jet Hot, More Performance and another I can't remember. Cartek has some bas *** LT's for big cube engines. Jet Hot looks like the best going. And of course, I love my Hookers. I personally wouldn't get either SLP's or FLP's. They used to be the best around, but then again they were about the only ones around <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

FLP's would be my choice over SLP based on install, clearance, etc.

Re: FLP or SLP whith do you suggest? You'd have to be crazy to put SLPs on any daily driven lowered car. I have FLPs and a minor drop and I've still scraped them before. SLPs are super low in comparison!
About the only thing SLPs have going for them is their stainless construction, which doesn't even matter if you get your headers coated (like FLPs, hookers, etc). Make more power, and get more clearance, get the FLPs.

Re: FLP or SLP whith do you suggest? [/qb][/QUOTE]Do you get an off road pipe and cats with SLP`s?... ..NO
Can you swap to an ORP or and back to cats in under 20 min as with FLP?...NO
Are the SLP`s a pain to install... YES
Do the SLP`s hang lower...YES
Have I seen surface rusted so called "stailess" SLP..YES.[/QB][/QUOTE]
Did i get an off road pipe with my jet hot caoted hookers? Yes....and the 2 together were only $700 shipped
Can i swap to cats with my hookers? Not with the hooker y, but i believe the mufflex y has cats
Are the Hookers a pain to install? HELL NO....just as easy as FLP's or BETTER
Do the Hookers hang lower? NO. In fact, some people have stated they GAINED clearance over stock
Surface rust? Not for a while,jet hot is very reliable and have a lifetimne warranty on rust and will fix it for free(not including labor or s+h)
Seriously, i can't see why anybody would buy headers that cost over 1K <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

Re: FLP or SLP whith do you suggest? The hookers are awesome!! good sound, easy install, and a GREAT price!! The only problem with them is the driver side o2 bung makes it hard to get the o2 sensor in. Jet Hot themselves just started selling their own LT's, might wanna try them out. They're just about the same price as the hookers too. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
