Now you need to install the mids, rear O2 sensors, tighten clamps, and negative battery terminal. Not a terrible job by any means. I rate the headers a 9.5, all headers require some mods to fit. I would highly recommend the Maximizer brand, quality was great, fit was great. Plan on porting the...

Starter wiring relocation and new parts needed on drivers side. ***Do this before bolting new header on.*** ***Make sure NEGATIVE battery terminal stays disconnected during re-wire*** NAPA Parts 60” red 4 gauge cable (#781163) 1”x36” Thermo sleeve (#7353967) Positive Battery Terminal...

-Drivers side Remove 1/2" bolt from steering shaft and separate halves. Remove (3) 1/2” nuts and remove the spark plug wire boot metal heat shield. Remove (10) 1/2” bolts, remove left side manifold from under truck. Remove all gasket pieces. You will need to unclip the starter wire from the...

These are the modifications needed on the passenger side. The heater hoses were too close to the header back by the firewall. I removed the two bolts holding the AC drier bracket to the pcm bracket. I installed two spacers between the two brackets and pulled it as far forward as possible...

Let’s start the install. NOTE*** Use anti-seize on O2 sensor threads, bolt threads, spark plug threads when reinstalling. NOTE*** I did NOT need to remove wires/shields/plugs because of my header design. You can do this on a lift or with a jack on the ground, most of the work is done in the...

Installation of OBX Maximizer Long Tube Headers – Part# MH12541 (910-3403-2) I bought them on wal mart dot com for $281 plus $119 shipping plus $24 tax = $424.00 I took a gamble with china knockoffs and saved over $2,200 from the big names. Upon arrival, very happy, very minimal effort to be...

A pic of the inside of the "cats"

100% I wrapped and re-routed the battery cable and starter solenoid wire up between the block and motor mount bracket, and then mounted a p-clamp at the front of the block in an open 3/8" threaded hole. Everything is kept nicely away from the header. I will do a little write up with part...

More pics.

Wiring is all done for the starter and the drivers side is completely back together.

They have just as much clearance as with the factory manifolds, maybe even more. I put new plugs in it last year, maybe I will toss 10mm wires and coils in it next winter when I get the valve covers done to match the calipers. Maybe I will get the intake done while it is off as well.

Hard to see in pics..

Drivers side went well. Had to clearence the the block/bellhousing. Also needed a longer battery cable. I will post up what I used when I complete the cable tonight.

No, no coating or wrap.

All stainless turns rainbow and dark colored after heat. Will look 100% better than rusty manifolds, and I never really noticed them lol.

Drivers side is all apart and cleaned, header is ready to bolt in tomorrow AM. Time to drink green beers.

Sexy and nice fit. Stage 8 locks on as well.

These are NOT cats, just very small resonators that I assume are supposed to look like cats lol. I did spend most of the day cleaning up the ports with a bit and then gave them a nice sand out. They were a little more rough than I wanted and it was now or never. They turned out good. Got the...

I am not worried about the tag, I was just posting the fact that the tag fell off. It is going in the recycle bin.

I checked them over. I am content that nothing will restrict flow, the last thing I want to do is start getting greedy and open up welds.
