3.5" Muffler

[J-B Racing]

Just about to start on my Single 3.5" Exhaust and would like to know which is the quieter and most free flow to run in the 9's as I am sure some are doing it.
I was looking at the Dynomax Ultra-Flow

Thanks
Joe

3.5" is more than you need for 9 sec. passes. I know a local racer that runs 9.7's on dual 2 1/4".

With that said, the Ultra-flow is a great design. There are other manufacturers that make the same style. Take your pick.

Ya, I read up on the Ultra-flows. That will be fine.

Thanks

I am going to be doing this in about 2 weeks, can you take a vid of which one you choose and post it here?

Thanks
