This is a subject that I'm interested in as I'm going to attempt to start fabricating an exhaust system next week.
I purchased a tube expander on EBay for $10. Napa has 2" exhaust tubing at $33 for 10'. And Canadian Tire sells a variety of bends.
I was hoping to have fewer bends than in the photos. By the way, the tranny mount gave me a chukle.
As I recall my Tiger was fairly simple. So I was going to start at the back and have the muffler behind the differential. The muffler I selects on Jegs(17711) has an input/output offset of 4", so it would bring the pipe in without a bend. On my Tiger the exhaust went under the differential, and I was hoping to do the same. Then through the pass-thru, probably a slight bend will be required to get closer to the center, then a slight bend to get to the exhaust manifold. In my case it will have to turn up about 45 degrees.
Is it necessary to go over the differential with the Alpine? If so, I saw a picture somewhere, I think on an MGB site were the fellow used a 45 , then a 90 to go ver the top and down, the another 45 to level out. I looked good.
I found the photo. This fellow put in a few unions to make final assembly easier. Not a bad idea.
More photos anyone?
Thanks,
Mike
