Quietening Sidepipes

[Don]

Paul, another alternative is to determine if any of the various motorcycle baffles might work. As an example, Harley Davidson has a low end " Power Baffle " part # V21299 , along with other baffles that are more/less restrictive. Baffles might require modification. Or, a combination of baffles that have been mentioned.

There are reverse flow mufflers, which would need to be modified, used for Corvette side pipes.

Take it that you are going to place the baffle internally and/or modify the turn out. Challenge will be not knowing how effective the solution is and the impact to performance/HP, such as reverse flow mufflers, until the side pipes are reconstructed

Thanks for the suggestions.

The elliptical shape of the exhaust exit due to the turnout makes adding anything onto the end problematic and I don't want to change the original appearance too much.

One suggestion has been to modify the tailpipe section so that the outlet can be rotated to face the ground when being used on the track. This could easily be achieved, but I don't know how much effect it will have on the noise levels. But maybe used in conjunction with some of the other suggestions, it could be enough.

Thanks again.
