    Default Custom Exhaust for the 351W

    Well, its been a long road (literally and figuratively) putting my Bird back together after I scattered the 5.0 motor in 2005. I was so pissed off at the whole deal I stuffed it into storage for about three years and then my dad's shop got finished and we brought it to his house. I live about five hours away so I have to plan my trips there to work on it. Some may wonder why the hell I would do this but its where I grew up and have all my car connections (paint, motor, machine work, and exhaust) so it makes better sense to leave it there. The 351W has been built for awhile now and the TKO was in it with the 5.0. The exhaust on the car with the 5.0 was MAC long tube 1-3/4" primaries with 3" collectors, a hand built 3" off road X-pipe, and a MAC 3" cat back system for a Fox LX Mustang with the rear portion of the tail pipes extended 8" with 3" pipe (lots of grinding, welding, and filing to get them to look right).

    With the 351W I figured it was time to up the anti and go big. I have a friend back home that builds race cars from the bottom up and he builds headers. We talked about what I wanted from the car and the possibility of a stroker kit later on down the road so we went with 1-7/8" primaries and a 3-1/2" collector. It took him several months to build them with all the work he has and he got pretty sick at one point but modern medicine fixed him up. The headers are done and I am headed back home this weekend to build the 3-1/2" off road X-Pipe and modify the old 3" X-pipe to accept cats so I can pass inspection here (visual only). Just thought I would share some pics of the headers in the car and I will update this thread as the exhaust comes along. This could take a couple of months as its time consuming and not cheap.

    Here are a couple of pictures of the driver side:

    I will put some of the passenger side in the next post.

    Hey Darren, those look great! Very nicely done. They're quite a step up from the Mac's.

    I was also checking out the Tubular K-member & A-Arms, studded AFR heads, fuel pressure regulators, adjustable brake proportioning valve...

    Thanks for the complement. Its a sickness I tell you. My dad bought the car new and I have driving it since I was sixteen so this has been a transformation over the years. The booster and MC are from a 95 GT so take a guess as to the brake package...I have no common sense anymore.

    Once I get the off road X-pipe done it and the headers will go to Performance Coating in Oklahoma City (http://performancecoatingsokc.com/) to get coated. The X-pipe with the cats will get rattle can high temp black.

    I had to look those up to see what you were talking about and when I saw the picture on their website (http://catalog.remflex.com/FORD_Head...t_p/rf3043.htm) I understood why you thought that. The AFR heads have a 9 and 3 o'clock bolting pattern and the exhaust ports shroud a 1-7/8" primary. What appears to be a thick gasket between the 3/8" header flange is actually an adapter plate so the 2 and 8 o'clock pattern can be utilized to take advantage of the larger primaries. The adapters use high temp silicone to seal them to the heads (which is already on them) and I will use a standard gasket for the header to adapter plate once they come back from being coated.

    Small update on the exhaust. Finally got up to Oklahoma this weekend and my buddy was back from North Dakota on a two week break from work. We got busy building the 3" center section with the X-Pipe and cats for the old visual for inspection stickers we have here in this part of Texas. Mike took more pics of the 3" than the other but it was a bit more complicted with the cats.

    More pics:

    This X-pipe was painted with high temp black with the exception of the cats as it will not be on the car that much. The other X-pipe and headers will be coated like the cat back with a ceramic coating that is polished.
