Mine on the 27 are capped and run through mufflers so it's pretty quiet.

Don's (blue bucket) headers are capped, but run through the down pipe that was made to hook up an exhaust system. His is loud, but more quiet than when he ran them uncapped. He drove it that way for a couple of years, not sure how he got away with that.

Dans (black rpu) originally had open headers but he bought the inserts from Sanderson to go into them. Even with them in it was loud, so we are experimenting. We first made a plate to go over the baffles, but with holes drilled for exhaust to exit. That was ok, but still loud. Then we bought a bunch of industrial stainless scub pads and wired them to the baffles to see what that would do. It did quiet them down a lot, but the first time he got on it the scrub pads disintegrated and blew out the holes. So now he is just running the Sanderson baffles until we find a better solution. It may take some welding of some diffuser plates inside or whatever, but inside the car with the top up it is pretty loud yet.

Dan's car doesn't seem to like being muffled. After putting the baffles in the first time we found one laying on the floor where it had blown out. That is why he made the round plates and welded the baffles right to them.

When I had my 23 I built my own baffles out of some 2 inch exhaust tubing that I punched full of holes. It really quieted the 350 Chevy in that car down to a very acceptable level.............well, at least I never got stopped for noise violations.

Here are the ones I built for that car.
