Matt,

When I decided to replace my exhaust, I wanted to go stainless so it would
be the last time. From Jim K., I bought the muffler replacement
pipes because they had the correct offsets to fit. I got the wye that goes
next because it would fit properly. I also got his muffler since it
was round and did not have the fitment problems of the Flowmaster. I went
to my previous employer and ordered a joint of 2&1/2" SS
schedule 5 tube. Went over to Columbus to see Steve Harman(GMC owner) who
runs Tubular Techniques for some SS 90 degree bends.
He had recently purchased a 3" mandrill bender. I purchased two elbows and
he gave me some elbows out of the "Uh-Oh" bin where
they had learned to use the bender. When I went to pickup the length of
tubing, the trucking co. had crunched the end of the package.
I was offered a 50% discount if I took the damaged tube. Since I didn't
need all of it, I went for it. I stopped by Jegs and got a mess of
SS band clamps. I didn't like the way the muffler fit, so I made a 153
degree bend and put the muffler between the dump tube and the
angle brace of the rear frame section in clear space. Of course, I had to
make a 27 degree bend and a longer tailpipe. Later, when I
realized how the big Caddy would bellow through that muffler, Larry Weidner
had found a 3" SS resonator and the tailpipe made a great
place to put it. I'm really happy with it.
