This custom exhaust was created using aluminized
2.5" piping (not mandrel bent). Originally, the mufflers used were Dynomax Ultraflow
mufflers (#17267) 3.00" in / 3.00" out 12" long and 6" round (That is
what is pictured). Now I use Dynomax Race Magnum Bullets part # 24215.
I found I needed 3 of them to make it bearable. They are 2.5" inlet/outlet and
4" round by 12" long. I changed to these mufflers because I was experiencing one
of the mufflers bouncing on the body on hard launches. There was only a 1/4"
tolerance with these (#17267). I also wanted to put on the Mecham exhaust tips on which
would not fit on the old system. The Race Magnum Bullets are louder but are a few pounds
lighter each and they don't bounce on the body at all.
There is an "x-pipe" where the two pipes meet right where the g-load brace is
located. The "x-pipe" consists of a 4" slit cut in each pipe then the two
pipes are welded together at that point.
This type of custom work is very difficult and can take 10 + hours of labor. There are
some places that have 1/4" clearances. A place called Road Tech in the DFW, TX area
has done this type many times. He used to charge $600 including mufflers. This was back in
1999 so I don't know what he would charge now. A friend of mine did the job who had a lot
of experience and is not associated with any muffler shop.
