Basically a resonator at the very end of the tailpipe. Worked for Cadillac and Buick, etc...

Farther to the rear, the cooler the exhaust and the less impact a muffler or resonator has on power output. A resonator should have much less impact than more restrictive mufflers. I was considering something like this for the Bonneville 505 build since I thought it would be cool to have a much quieter exhaust and still blow the doors off the competition on the street.

It would be very interesting to know the db drop with resonators and also how much they actually restrict horsepower.
