I don't personally have any Dyno numbers but I am sure they are consistent with the low end losses and high end gains as is common with such a setup.

My butt dyno can't tell the difference but my ear dyno is having a blast!

As Mooty said; its a SAFETY MOD

Just like on my Ducs! Instead of warning deer; I'm alerting the random pedestrian of the fury Hell hath unleashed upon the 'burbs!

I installed them on Sunday. Took two hours total and two beers!

Having a lift in the garage makes all the difference for a job like this.

Saved much time by not pulling the bumper and instead realeased the headers and rotated them out of the way and the big side anchors were easily removed as was the center anchor.

70 friggin' pounds of dead weight removed! Seriously.

Took the car for a rip and my ears were treated to an aural symphony not like anything I've heard this side of a pure Cup. There is a snappy crackling snarl at throttle lift and as the RPMS rise so do the hairs on the back of my neck!

Can honestly say that these may be the finest sounding pipes I've ever installed. The headers of the 991 GT3 do not need to be messed with. The collector merge is huge and smooth with zero abrupt changes in course

Under 4K RPMS in town and they are almost sedate (well not quite) over that and all hell breaks loose. The acceleration surge over 5K is much more than I would have expected. Hard to differentiate down low as I'm not driving there...the sounds are too addictive to go below 5K.

At 9K I'm pretty sure I'll need to keep some tissues handy to clean up the messes.

Will try to make a video or two this weekend and post it up.

I was analyzing the footage sent by Leif997 and some footage I took of a GT3 Cup Middle East race with a Supercup exhaust (it's a straight pipe out on those cup cars with the Supercup configured exhaust, but sometimes they just have the center section installed to quiet them down) and they sound practically in distinguishable.
