I started out with 2-1/2" and "reproduction" HEMI mufflers, way too quiet! People used to ask, "does it really have a HEMI?"
Well of course it did, 540" 10.78 compression with solid roller!

Then I went with 2-1/2" LONG Dynomax UltraFlows. Better, but still to quiet.

When I installed the Gear Vendor I had to replace the exhaust that was in the way. I went to TTI 3" with SHORT Dynomax UltraFlows. Now it sounds just right! There is no question that it makes power from the idle sound!

Cruising is pleasant and mellow, add throttle and it flat out "talks to you"!
