I run autox events and some track cross events. Nobody runs a sound meter yet but I don't want to be the guy that gets a club banned from a venue because of noise. I also despise all the folks driving UTVs and dirt bikes through my neighborhood so I need to know if I'm just giving up and joining them or if I can still complain about them while running this exhaust.

I got a quote with mufflers and the added cost isn't an issue, but I'd like to know if anyone has objective measurements with or without mufflers before I pull the trigger.

I'd be ordering it with cats as well.

ha good stuff. i live on a street aka a racetrack in SoCal with 100's - 1000's of sport bikes on any given sunday with jay leno quietly chugging uphill daily. i have a straight piped flattrack bike and i run the tt as loud as i can. i was "them", before "them" was cool. still, i complain lol good luck.

I'm no expert and I don't have any empirical data, but I can't imagine you'd have an issue. The turbos muffle the exhaust sound a lot. GT3's sound much different/louder, for example.

My stock 991s w/PSE is louder than my turbo with 100cel Milltek. I'm sure the x-pipes are loder than mine, but if your track is ok with 9k rpm GT3 music you're fine.

I've run or been around enough different 6tt/gt2 exhausts... if you think you're maybe on the fence get mufflers/resonators
