Default new SLP long tube headers!!

I was here: http://www.ls1motorsports.com/ls1cexhaust.asp and saw they had new SLP longtubes for sale, that are supposed to be real good. Anyone have these?

Also, does anyone know which ypipe would fit these?

What do you guys think of these? Here's a little writeup, which makes them sound damn good!!

The engineers at SLP Performance Parts have done their homework. SLP is proud to announce the release of the industry's first full length headers made with tuned tube lengths for LS1 powered Camaros and Firebirds. The length of each header tube was calculated to maximize scavenging from the exhaust. The tube lengths allow each exhaust pulse to create a vacuum in the collector at precisely the same time as the next firing cylinder's valve opens. This acts to pull the exhaust gas pulse out of the cylinder. The result is more efficient exhaust scavenging which translates to faster revs and increased torque and horsepower. While equal length headers are good, tuned length headers are the ultimate! SLP's new headers utilize stainless steel 1 3/4" primary tubes into a 3" stainless steel collector, then the headers are COATED with a CERAMIC THERMAL BARRIER high lustre coating. The headers utilize OE style and quality flanges, and are completely compatible with EGR, oxygen sensor and air pump systems. SLP has also designed a new stainless steel 3" y-pipe to work specifically with the headers. The y-pipe requires our optional high flow catalytic converters.

You wont see that type of gain on a stock car. Maybe if you have some heads and a cam on the stock exhaust manifolds and switch to them you could.

Im making 350 RWHP and 360 RWTQ with just headers, exhaust, maf ends, ported TB and a lid w/filter. Thats the only gains to see on the dyno. Oh, also a MAFT.

Keep in mind that the product descriptions are obtained off of the manufacturers website (in this case, SLP), and I have read a TON of bad things about these headers, from fitment issues, to poor performance gains (if any, I can remember seeing some people actually lose power), to poor customer service (I have experienced this first hand <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> ). Do a search, then ask around, and you'll see...

By the time you buy a y-pipe, you are in the same price range as Whisper, TTS, and FLPs, all of which should produce better results, IMO. Heck, before I spent $900 on SLPs, I'd go with Macs, ORP, Catback, and still have money to spare. Again, just my .02, FWIW. Good Luck, Shawn

I only have 1 complaint. The finish sucks!! Heres some pics:

<img src="http://www.imagestation.com/picture/sraid23/p1e9c21e0e2dd25cd1eb5aa5cffae8f90/fd9c6872.jpg" alt=" - " />

Also I broke the y-pipe:

The headers are only like 8 months old. Thats not oil either on them. The whole header is turning brown <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

Country Boy, for only being 8 months old those sure don't look good. Coated stainless steel headers should hold up a lot better then that, you should contact SLP and e-mail them those pictures. If they can't do wright by you I let everyone know they don't stand by there products, hopefully they will.

Country Boy:

What was the cause of the Y pipe breaking?

Have you had ground clearance issues?

Default Re: new SLP long tube headers!!

Last Friday I picked up my car after having SLP LT headers installed, as well as the SLP loudmouth cat-back system. Let me tell you, the car runs great, it sounds great, and it looks awesome. Next week I'll be taking it to the shop to get it on the Dyno .. hopefully I'm not disappointed. One thing though that you should know ahead of time is that the setup (LT headers,cats, Y-pipe) hang really close to the ground. I have my car lowered about an inch, and the setup is less than 2 inches from the ground. I just need to be careful .. other than that, can't complain yet.

Dave or Jeffy if you're reading this post I'm disappointed in SLP, I've always been a supporter of SLP but in this case I have to give you two thumbs down.... I'd give you more but I only have two thumbs.

Other people with coated headers have experienced similair discoloration or rust marks forming. I've seen it on MACs (happened to me. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> ) and on FLP as well.

The SLP's I've seen have been well made and the set up is good for someone who needs to bolt-on a set of cats every 2 years to pass emissions. On a 346" motor shifting at 6200 or lower they provide good gains, especially in mid range torque. I would not use them in high revving applications; other headers perform better on the top end.

Of coarse youre going to gain with headers, I didnt say that. I just said that on a basically stock car, you wont gain the proclaimed: SLP STATES GAINS OF UP TO 41 HORSEPOWER AND 58 FT. LBS. TORQUE INCREASE AT THE REAR WHEELS

Let us forget for a moment the discoloration.

What had SLP said about the crack at the weld? How much larger is the crack now?

The crack is a little more than 1/2 way around the weld, so it was probably starting to peel open. I dont have that Y on there anymore. I have true duals now.

Default Re: new SLP long tube headers!!

Here's my take on what caused the crack, when installing SLP LT headers you need to leave the headers loose when installing the y-pipe. Once the y-pipe is connected to the headers you can tighten the header bolts down, the tighting of the header bolts draws the header outwards at the y-pipe (causing pressure). If there was a weak weld at the y-pipe it would cause it to crack, JMO.

Strange HORSEPOWER said it was defective coating, sent out a new pair right away and paid to have the old ones picked up. Mine was peeling right off at the collectors too.
