I am considering purchasing a set of shorty headers for my '06 4.0L automatic 4x4. Summit Racing offers a set of PaceSetter shorty headers for $183.95 (summit part #PSM-70-1387). Amazon has the same set for $166.50. Summit includes the studs/bolts, Amazon does not. I've contacted PaceSetter to see if I can get the bolts separately and am waiting on an answer.
Could I reuse my original manifold bolts? Summit Racing has a set of bolts for $5.06. Amazon's shipping is free, Summit's shipping is $11.95 for the headers w/bolts or $4.95 for just the bolts. So I'm looking at $195.90 total if I order from Summit, or $176.51 total if I order the headers from Amazon and the bolts from Summit.
Does anyone have any advise on installing the headers? I'm out of state, so I can't look at my Ranger right now. I would like to order the parts and have them waiting for me when I get home. Relocating the cats is not a problem since I have already purchased a pair of Flowmaster high flow cats. They were too large to weld in place of the original cats so I was already planning on building a new exhaust from the manifolds back. I have already installed a 2.5" Flowmaster single in/single out muffler, with a turn down. I found a 2.5" in / 2.5" out y-pipe by Lawson Industries part #66906 that I want to install in place of the lowest cat. I've already gutted out the lowest cat and reinstalled it since it was clogged up.

 

Ok so I contacted PaceSetter Performance tech support and inquired about purchasing the header bolts separately. They informed me that the bolts are included no matter who you purchase the headers from, even Amazon. So I guess the information Amazon has is not correct. So it's $166.50 from Amazon, gaskets & bolts included. Pretty good deal!

 

Be careful because those headers look awfully cheap and you have to make sure you get the headers with the EGR tube hookup otherwise it won't work, also, I am guessing you live in a state where emissions are not required otherwise you would not pass. Sorry for late reply
