Pacesetter Longtubes

Use a ton of PB blast on the manifold bolts several times over several hours before removing them. Lots of people break them, but if you soak them first then it will make your life and this job a lot easier.

Is pb blast just like dw 40 or no

WD40 I believe is just a lubricant. PB actually penetrates the rust and helps dissolve the rust.

Yea I am looking at a cam and a prochager within the next year so warranty will be out the door. I was thinking of selling the factory Y on craigslist or scrapping cats (whichever more Profitable) and buying some transmission upgrades servos, piston acummulator and transgo HD2. Trying to find a write up on the acummulator piston install.

If your looking at a procharger and your serious about getting it! You'd be wasting money on a 60e. Buy an 80e put a hd2,vette servo and you'll be good. Also I hope you put a blower cam in it. I'd wait on cam for now n do it right from the beginning.

I skimmed through the 80e conversion but saw some people were having problems with the 4x4 swap. My transfer case selector is a manual version on the floor and I think most of the people that had problems with the electronic selector. Would a 80e with transfer case work with this set up? I know I would most likely have to change driveshaft length.

So just an update, I got the headers almost complete on the 2010. The rear driverside bolt is a b*tch to get to. I pulled the inner fenders which does make things much easier. Passenger side was everything you could ever ask for when working on a something, came right apart, header slid in from the bottom. Driver side I had to go through the top and did not need to disconnect steering shaft. I would have had a bit more room if I would have disconnected the front driveshaft but was able to work around it. I needed to cut the original exhaust before the YPipe clamp since the bolt was rusted so I could not complete until I got another piece of pipe. Another tip is to completely remove the transmission crossmember this helps a lot.

Good to hear you got them in with out to much issue.. Only problem I see is if you get alot of rain or snow, they are going to be ready for replacing within a 2 year period..

An issue I had and it may have just been my set, I had them on for about a year and then swapped motors and when i put them back on they seemed to collapse in and the drivers side started to rub against my 4wd drive shaft but I just pulled the shaft and did a little massaging to the header and it doesnt rub anymore

Just hit them with some plastidip

Another update everything is on and I just need to go through and retighten since I have been through the first heat cycle. My god you feel every exhaust puff there is, I had a series 10 flowmaster on the truck prior to this since and it sounded really good. Now it’s crazy loud so I think I will be shopping for a muffler soon. Not sure about anyone else but I’m still really surprised I cannot turn the tires over from a dead stop. I have a tune (with supposed torque management reduction), intake, header exhaust, factory 265 tires and 3.42 with stock torque converter. I cannot get these damn things to move on a dry road or even trying a brake torque. Any one out there with a newer 4.8 having similar problem?

Here is a link to the Youtube video on stock exhaust/ flowmaster with factory manifolds. http://youtu.be/iTSZqJQ6CqA

its the 3.42's and stock converter swap to 4.10's and at least a 2800 converter and you'll burn them up
