GMCer's,
Just got back from Ed Hanson's Muffler Service. True to form, Ed built
a masterpiece under the GMC.
2 1/2 aluminized pipe from the manifolds connected with Ford 3/16
performance flanges v'd into a single 3" flanged (same Ford flange) pipe
that goes straight through the frame to the rear. The whole center
section can be dropped out for engine/trans work. He used a high flow
walker Camaro 3" inlet and outlet muffler in the rear with a 3' pipe
exiting in the same spot as the original. He did add a small
performance resonator about mid point. The system is nearly
unnoticeable inside the coach and sounds mellow but authoritative and
crisp outside. Big difference in performance. My old mufflers
(original) were fairly plugged up and swollen from backfires. The
exhaust piping was transparent in most places and in my opinion, too
small. Even though the muffler and piping are under the rear of the
coach, they are not visible. They tucked up nicely and Ed added a heat
shield around the muffler for an extra measure of safety. All that's
visible is that great looking 3" chrome ehaust tip out the side. It
feels like a new coach to drive and my first reactions are that the
throttle is more responsive, more bottom end grunt. I snapped some
photos but left the darn camera in the coach last night..
