I am trying to decide between the LPP and OBX. Can't afford Dynatech, Stainless Works, etc...
I just put a set of the cheaper ones on. I think there all the same just sold from different vendors. You will have to re-use your old manifold gaskets or get a set of aftermarket ones, the set they send with the headers are junk!!!! The quality is pretty impressive for the money. The collectors are only 2 1/2", but they seem to get the job done. I don't like the "doughnut" gaskets for the collector connection, but other than that there fine. I'm waiting to see how well they hold up in the winter.
in the footnotes for the more expensive ones it says it won't fit 4x4
They fit my 04' 4x4, but its tight!!!!!!!
I ended up getting the LPP headers for $450 shipped.
Where did you get the LPPs for 450?
from LPP GM GMC Truck Silverado Sierra Stainless Headers
then I got $50 back
Oh nice. Im going to be purchasing headers soon and Ive really liked the look and quality of the LPPs, the only thing Im worried about is them rusting because I live in Connecticut and we get snow, now I dont really drive in the snow since my truck is 2wd but I do drive it occasionally in the winter. I know alot of people say stainless wont rust but I have a stainless exhaust on another truck of mine thats been on for a little over a year and its starting to rust not like flakey rust but just brown ugly surface rust. Now Im not totally sure if it matters on the grade of stainless or anything, maybe someone could chime in on that?
OK i have a question i put on a set of pacesetter 3inch long tubes and ran true dual 3in exhaust to a spintech dual in dual out 3in do i need to put an x pipe in there to get more back pressure cause i didnt really notice any difference when i put them on ??
I thought x-pipes scavange exhaust better, reducing back pressure. Maybe a good old fashioned h-pipe will do it.
From what i could grasp from just looking at the kits, the more expensive one is a full kit with cats, gaskets, clamps etc. The less expensive one is just the headers and gaskets. 1 kit is emissions legal the other off-road use basically.
I like that the LPPs have 1-3/4" primaries and 3" collectors. Most of the cheaper ones don't have that.
All the cheaper headers on ebay are made from 304SS. The LPP's are made from 321SS. A little more rust resistant and does better when you weld on it. The welds are not supposed to oxidize as easy as 304. :DQuote:

those LT's are definitly interesting at that price. It says no EGR. what does that consist of as far as removing the EGR?
Your GMT900 truck doesn't have EGR.Quote:

Which year truck? The Pacesetters for the NNBS suck. Either way, 1 3/4 would be right for you.
Its a 09, why do they suck? What headers should i be looking at?
I have an 08 4x4 and got their 4x4 headers as soon as they came out. Had hell getting them to fit together.Quote:

Definitly dont have a 4x4, had a nightmare about it one time tho lol
How is the fit on the two wheel drive version?
I've heard they're okay. My issue wasn't with the headers fitting, it was the Y pipe. It can't be put together and THEN put on because it wont slip into the headers that way. It has to be done piece by piece. I ended up taking a sawzall to mine and cutting about 1" off each connecting piece and then grinding the edges down smooth. They ended up fitting a lot better, but I still had to take a BFH to one side to pound it into the other side (the crossover in the middle). Now I have a dented up Y that leaks if I don't tighten it every month or so.
Headers are very much a case of getting what you pay for. A lot of guys run pacesetters because they serve the purpose and are cheap, but they're also JUNK.
So who makes a quality header thats not gonna break the bank to bad?
i had the same issue with my y once i got the headers bolted down even with the crossmember holdin the transmission gone i still couldnt get the y to go on i had to completely unbolt the headers and have a friend hold them with i got it pieced together then rebolt everything back up...now looking back i should have just waited one more paycheck and bought a better pair they get the job done but were a hassel to get on and probably gonna be a hassel later down the road after they get a few years on them

What about LPP? They said they would have the NNBS longtubes in stock soon.
