Question Exhaust cutouts - instant open exhaust

I know the V8 boys use these all of the time right after their headers, but would they work on our car?

I'm thinking about trying one, but I don't know if they would hold up to the heat of the rotary. Anyone have any first hand experience with using one of these on a rotary flowing BIG CFM?



An instant open exhaust.

Steel, black hi-temp finish, 3 in. diameter tubing, exhaust cut-out

Just weld in a Summit exhaust cutout behind each header and you'll be able to convert to an open exhaust at the track. Precision MIG welded.
