After 4 hours the LPP's are on. The look great, and fit ok. I installed them from the bottom. Slid right up. Installed the passenger side first.Put all the bolts in hand tight. While tightening them with a 3/8" rachet one broke off. I think maybe lpp should supply these with some grade 5 or better bolts. Its the one in the center thats side by side so i think i should be ok.
The drivers side went in effortless. Just the last bolt towards the rear is hard to get to.

The y pipe isn't the greatest fit. Had trouble getting it fitted into the headers. After I wrestled with that for 30 mins it finally seated. Well the y pipe and passenger side header almost hit the floor board. After i put the clamp on it rubs the floor board.

Next to the connector that connects to the stock donut. It didn't come with any bolts. Lucky i was able to use the bolts from the egr mount, and a nut from the stock manifolds. Got it connected, now it won't line up with the y pipe. So I might take it to an exhaust shop and have them just weld it all up.

Oh and i broke the dipstick while trying to remove it. So that will be ordered tomorrow.

Other then those few issues im pleased with the headers just the fit's a little off.

:hmm:

The y pipes are a bitch to get together with the pacesetters too. Kinda weird that it rubs the floor though.

lets see pics and hear a video. I want to order the headers only then take it to an exhaust shop for a custom Y to work with my diff drop :evil:

y-pipe alignment (pacesetter) with my exhaust was a pain in the ass to say the least. Had to get the 10lb mini sledge a couple of times to get everything to line up.

Odd that it hits the floor, but if you remember the test truck is a lifted 4x4, so things are going to be off (seems odd they didnt try a stock truck for a test vehicle).

Sucks about the bolt, did it snap clean off? if theres some stickin out you might be able to get it loose with some vicegrips or weld a nut on the end. If its in the head, you might try that EZ-out thing they advertise on tv since its a fresh bolt. I doubt it'll seal right with a bolt missing.

Make sure you dont over-tighten them when they start to seat in the heads with heat cycles when you re-tighten them, little bolts don't like to be torqued very much :crazy:

Thats interesting... I have no problems with the fitment on mine at all. Not close to anything.

About the Y on my lifted 4x4. The 4x4 isnt going to matter with headers and such. I took the driveshaft out and put it where it would be stock when we did the mock up so that wasnt an issue. Everything fit cherry on my rig. I guess thats just due to GMs tolerances on things.

Its aftermarket shit, its not gm, so u are always gonna have fitment issues. Everyones truck is a lil diff and all the headers dont come out the same either, so there is ur variable. Just be happy they work for 500 bucks, thats dirt cheap.

Ok got some pictures. Ran to Napa and picked up a 3" band clamp to try and fix where its leaking at the Y connection. Helped a little but still leaking.

You can see here how close it is to the floorboard.



Here's where it bolts up to the stock mount, doesn't fit well here either..

They don't hang below the frame which is good.


I think it's going to be close here on the Y when I'm fully laid out.


Passenger side.


The broke bolt.


Steering shaft looks like it has enough room.


From the front.

Here's a picture of that side on my sons truck. It's kinda hard to see the clearance but there is plenty.

Not says you did anything wrong but the flange holes are oversized so you can adjust the headers up and down a little for fittment. But everyone else is right also there is a lot of difference from truck to truck and even tho the headers are made in a jig they can vary some too.
I am glad everything went pretty well for you.

Don't get upset but I have a few suggestions. Instead of including free shipping on them for $500 shipped. Get rid of the shipping, add in the appropriate hard ware for the kit. IE. Stainless bandclamps as opposed to the u bolt clamps, grade 8 bolts, then charge the customer the shipping, I'm sure it all could be done for around $500 still. It would make the installation process much easier. That way people aren't out running around for the parts.

This is just my thought, maybe some of the other guys who got them will chime up with some feedback also. All in all i would do it again, the headers are great!

Id rather have the free shipping. I can get bolts and band clamps cheaper than the price of shipping.
