Default SLP Headers... Good or No Good????

Have seen mixed comments on the SLP Headers... mostly comments on installing the drivers side exhuast system. Are they as good as the FLP's, the Mac's or the Hooker LT's??
When using aftermarket cats, does the system line up with the stock "Y" pipe? Or does the Header System come with a new "Y" pipe? Or do you have to buy a new "Y" pipe? Or do you need a professional Exhaust Shop to hook the headers up to the exhaust system???
Also... when changing plugs, I have heard good things about the FLP's, Mac's, and Hooker LT's, such as being easier than changing a plug on a LS-1 with stock exhaust manifolds. Is it harder than with a stock manifold, about the same, or easier to change the plugs than on a stock manifold with the SLP Headers???
Do you need their fancy offset plug tool to change the plugs with their Headers?????
Thanks for any and all comments....

From what I have seen, the following applies to the SLP headers:

Pros- high durability (ceramic/stainless), high quality (as far as welds, etc...), good mid-range power, 3" Y-pipe

Cons- passenger side install a bitch, hang low, some feel that performance gains aren't up to par with other headers

SLP's seem to be tricky to install, but that's something you only deal with once. Performance and durability is something you deal with every day afterwards, and they measure up in those categories.

They are workin great for me. I have pushed about 700 RWTQ out of them. Im making 350 HP and 360 TQ with only a couple bolt ons, but I do have some problems....

the Y-pipe sucks, I split mine practically inhalf <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> where the 2 merge to 1.

<img src="http://www.imagestation.com/picture/sraid23/pbfb3e2229f86f5ad63bba6009caf50d3/fd9c6873.jpg" alt=" - " />

and the finish is starting to suck, but people are starting to say, "Its normal" <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Other than that, I like them and no, theyre not hard to install <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Thanks for your comments. Sorry to hear that the "Y" pipe split and that the coating is coming off.

I have seen this topic come and go.

Most of the 'slams' of the SLP either come from people that don't own any header or some other type.

I have had mine for going on 18 months. Next to the nitrous, the SLP are the best mods yet.

Normally, you get the entire package from SLP: headers & y-pipe. You can either get the ORP or cats. You can get the install package or not. If you are in a state that has emission laws, you'll need the cats. I would suggest that you get the install package also.

Install is not easy for any of the long tube headers. They are a pain. It is normally best to have a professional install them. If you are near one of our sponsors that would be your best bet.

About the only 'problem' is the passenger side header hangs a little low. Don't plan on slamming the car to the ground. With my set-up I have had no problems - I just avoid pot-holes (we all should), and steep drive-ways.

Good Luck look at the sponsor section I believe there was a GP on them.

David

Slp's on the bird and Flp's on the SS. I'll take the performance of the Slp's anyday. The FLP's just dont have the low-mid range they do and up top they both rock.

Thanks for the comments Dave. Unfortunately I have a steep driveway that I have to deal with. I will have to weigh the HP vs the paracticality of the LT's in my situation. Thanks for the comments. I have not found any problems with any of the SLP items I have installed to date.

I've had the SLP's on for over a year and have had absolutely no problems. They look great, and with the loudmouth, sound even better. The SLP's work great for my application, AutoX.

Default Re: SLP Headers... Good or No Good????

Last week I installed a set onto a friends car. I would not want to ever do another set of those again. It took way too long. I had the stock crap off in 2hrs, only because it was so hot out. The headers took a long time to get in.

FLP's get my vote for the easiest to install & best groud clearance, the con is that you have to buy the crap Y pipe and convertors.

Grotts were also easy to install, and get my second vote. These are almost as easy to install as the FLP's, but are reported to give the most power, but do not have the ground clearance of the FLP's, but have better clearence than the SLP's.

I have had personally the FLP's, and the Grotts. I like the power of the Grotts, but I would have bought the FLP's if I could buy just the headers.

The Hookers seem to be the best deal out there, but I'm still waiting to hear how they are to install, what the ground clearance is compared to the others that are out there, and the dyno results. Good luck with your choice.

I loved my SLP's but switched to Grotts looking for more power. NOT. Wish I had the SLP's back. The Grott headers are beautiful, but the ypipe ruins the package. SLP delivers everything you need with a high quality, trouble free product.

I have been driving myself crazy deciding if I want to give the Grotts a try. I have the SLPs now and they have been great to me, with the exception of the ground clearance issues. My passenger side scrapes on anything it possibly can. Power wise I cant give any definate gains, as they went on with my heads/cam. All in all I think the SLPs are a good header. They definately have one of the best Y pipes on the market.

I have the SLP's and have been in cars with Grotts and FLP's, I wouldn't change, the grotts y-pipe is total crap. The FLP's are the only choice you have if your car is lowered.

Yes, the install sucks, and on a stock ride height vehicle you will have 4 1/2 inches of ground clearance at their lowest point. Which that is only a half an inch lower than the stock y-pipe on the 01/02 F-bods.
