Hey fellas got a question I'm going to run my OT headers. If I run water injection on them will that quiet them down some? And or can I run water injection and baffles? Our local Johnny law revenue generators have a hard on for writing excess sound tickets.

It will quiet them down a little bit (three or four decibels) at anything but idle, which is mostly when LEO'S notice you don't have mufflers.
You can run baffles with water.
When we had to quiet down the race boats, we used the Rewarder baffles with Drew Shotguns mounted on the back. Was good for nearly 8db, but more importantly, lowered the frequency a little. Which tricked the decibel meters.
We also ran an extra water nozzle at the baffle. Quieter than mufflers from Borla.

Cool thank you GT , yeah I'm needing to quiet them down and cut down on the heat too, I'll have to look for some baffles.
