Each exhaust system is designed and dyno tested at our facilities. All of our testing is done with that Harley SE Race Tuner.

Performance increases are about up to 15% with the proper tune on the bike.
The Louvered wrapped baffle is the quitest baffle for motors 96" to 103"
The Perforated wrapped baffle is the medium sound baffle for motors 96" to 113"
The Perforated baffle is the very very loud baffle for motors 96" to 113"

Note:
When using Woods Cams the best baffle to use is either of the Perforated Baffles.

At idle,the motorbike is deep,boomy and full of character. Not only does the pipe look good, it is a wonderfully sounding experience for the rider. David Rash, Pope of Pipe
