Brian,
I have a 3.6 VRAM in my 80SC. It has the "Happy crab" muffler with stock 993 heat exchangers. I think the tailpipes are 2.5".
The drone and db's are starting to wear thin. Do you sell the vacuum activated valve on it's own? I'm thinking having the valve on one pipe and maybe a baffle on the other pipe would help keep the dbs down when cruising. Or maybe you have a full muffler setup to address this. I track the car occasionally with our local PCA club so would like to have increased flow when pushing it.
What are your thoughts?
