You would see with the supercup set up around 125 db.
We can build this in inconel or SS. We try to stay in factory tolerances.

I assume the 125 db is measured at the tailpipe? Have you measured it farther away, as most sanctioning bodies on the West Coast do? For ex., Laguna Seca measures it at 50 ft away.

Let me put it this way. This exhaust does not work for places with a noise restriction

They look great but there is nothing about these that look remotely quiet. I have a similar set up and they are max power and max loud.
