I am running LT1 Extreme Street, which specifys a muffled exhaust. I want to run my usual 12" Dynomax bullet RIGHT off of my MAC y-pipe that I have run at bandimere and had no problem with at 'muffled' races. But, will this fly at the shootout? The reason I'm wondering is because with the Dynomax, I'm am just as loud as an open exhaust. Is there a decibal limit for the shootout? And specifically, Lt1 Extreme?

 

I’m not sure sound can even travel at your elevation; you’re up there on the edge of the atmosphere in the Denver area.

From what Tony posted previously, bullet mufflers are OK.

As long as I see a muffler you will pass. Bullets are fine.

 

Great! Thanks, that is good news. Clark

 

Hmmm how about a turbo with no muffler? Its a lot quieter than most bullets or even catback cars.
