Muffler delete 8.3 RE?

Has anyone straight piped an RE with one of the big 6's?

How did it play?

I am tempted but afraid that I may make it too loud.

I mentioned it to the gent that runs the local bus barn and he though i was nuts........

As badass as I know it’ll sound I have to agree that it will be loud AF. You’d get tired of the noise after awhile.

Maybe make two exhaust systems. One that bypasses the muffler, and another that goes through it?

Do an exhaust cutout! Best of both worlds and changeable.

With a rear engine setup the engine exhaust will only be loud to those behind you or bystanders along the way will hear it.

I'm wondering if there is any benefit other than it sounds cool. With as big and long as that exhaust system is, I doubt deleting the muffler adds any noticeable power. If those who say it does were using a Butt dyno, they are notoriously inaccurate. As many of us that complain about how loud our bus is under normal operation , why would you want to make it louder. I'm all into a powerful sounding exhaust on my rides, my bus I'd like to keep as quiet as possible.

I have done a muffler delete on my 8.3 RE bluebird. The only way I can hear the thing is if I open the windows! Closed I don't hear it. It runs a little better now. The turbo spools up faster. I don't know what the other motorists think.

A free flowing exhaust increases power and economy. It also lowers the exhaust gas temps since the turbo is spooling up better without the restrictions. I straight piped my front engine bus and it is no louder in the front of the bus, just the exhaust tone is much better and louder out the back.......
