SLP Long Tubes and Clearance: Ground Flat! I have slp longtube headers on my 99 Z28 for about 2500 miles. The clearance is Like 2" from the header to the ground. Occasional contact (routine and can't be avoided) causes the headers to GRIND AWAY and to grind flat. This could cause a blow out as the wall thickness declines. I have about a 4" x 2" section on both haders which is now flat. I think the wall is down to 1/16" thickness.
Need some kind of metal skid plates for protection. Any ideas?
I am sure many people have this problem with the SLP longtubes!

Re: SLP Long Tubes and Clearance: Ground Flat! I assume your car is lowered. When I had the SLP's on my car, the clearance was exactly 4" at the lowest spot. No problems, even over speed bumps.

Re: SLP Long Tubes and Clearance: Ground Flat! You are right it is 3.25" but I am still scrapping flat and need some kind of skid plate. I will get some pictures of the damage next time it is on the lift.
have to do something before I tear through the sidewall

Re: SLP Long Tubes and Clearance: Ground Flat! you can get about 4" by turning the
brackets horizontal.. this is vertical

I have not scraped much of anything after
if moved the brackets.. 12K miles.. on headers.

Re: SLP Long Tubes and Clearance: Ground Flat! Man that sucks I'm glade I'm going with FLP. I would rather deal with them hitting the floor board then scrapping on ther ground. Well good luck with it.

Re: SLP Long Tubes and Clearance: Ground Flat! Not to add to your dilema, but with headers RIGIDLY bolted to your heads I'd worry about bending those things as hard as you seem to be hitting em. Not to mention the effect on your heads from force at the header bolts. Sorry I don't have any ideas <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Re: SLP Long Tubes and Clearance: Ground Flat! That's strange, I have SLP long tubes on my 99 and I have no clearance problems at all. I'm not sure what the actual clearance measures though, as I have never measured it. Sorry to hear you are having problems, that sucks. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Re: SLP Long Tubes and Clearance: Ground Flat! No damage to the head bolts, heads..., just the headers are scraped flat. I am going to steel wool the rust off the metal and spray coat them to prevent more rust formation. Then I am going to look for someone to weld some metal at the contact points. Not what I expected when I bought the slp longtubes...
Re: SLP Long Tubes and Clearance: Ground Flat! i know i have a good 4-5 inches between mine. The only issues i have are with really tall speed bumps...
but as far as LT's go, none of them are perfect. FLP's have probs and SLP's have probs. Mine was one of the first batches to ever come out and they LOOK beter than brand FLP's still. There coating is awesome. And i dont see where Mac's are FLP's are performaning any better.
If you have 1200 bucks get FLP's, but im not complaining cause mine were only 800 total <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

If you dont care to read my opinion dont read my posts...
How about 7RWHP peak difference between the two in favor of the MACs? SLPs had more torque at around 2500-2700rpm but then the Macs passed them(~8RWTQ @2500-2700rpm advantage for the SLPs) I am sure different cars will get different results though
cheers,
Chris

chris,
You are stating that SLPs are crap based on that alone? You're a tough customer man! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Alot of times people post responses based on their opinion that has nothing to do with facts. It only has to do with the fact that they bought something different which is of course better because it is what they have. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
I am always ready to hear opinions based on facts, but I personally believe that all long tubes are close enough in power to say buy what appeals to you and your needs. Like installation, whether you are using cats or not, what other mods you have, how much money you want to spend, is quality important or just performance, etc.
Moral:
Opinions are like ********, everyone has one.
Facts are valuable and indisputable (although some people will still argue). <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
ps - I am in no way trying to offend you, just like to stick to facts.

Re: SLP Long Tubes and Clearance: Ground Flat! I've got SLP LTs on my 99 vert. Not lowered. I've had them on for a couple hundred miles and have only scraped them twice. Both times at the same place coming out of a parking lot with a slightly steep decline to the road. I do have the cat clamps turned to the side and try to drive across things like that at a slight angle, which helps quite a bit. No floorboard banging either. Have to say I'm very satisfied with them, the quality and finish is top notch. Was somewhat disappointed with my dyno numbers but was the first time I had been to a dyno and hadn't adjusted the A/F ratio at that time. The operator of the dyno isn't a fuel injection guy from his own admission and at the time I wasn't either. I hope to get back to the dyno soon, now that I think I have the car dialed in better.

However I do have to be extra careful where I drive and how fast I go over some road hazards.
