I was totally going to do this with my exhaust. I've been looking at various setups and really liked the vacuum actuated ones that are similar to what the ZR1 Vettes use and still might but first I have to get these other exhaust parts (PCD's and long tube j-pipe) installed so this Big Boy can breath! Lol
Love it dude, great work and you have officially made me j-e-l-l-y.

You stole my idea and made it unoriginal!

Not completely complete, still some minor details (paint part of the rear diffuser a different color) and grille to finish and some final buffing but here are some of it in the wild

But just out of curiosity, what purpose did you have in installing a butterfly into the inside of the exhaust tip? It almost looks like a single exit muffler with dual tips welded on and a butterfly on one tip. I had originally though about doing a butterfly, but I had considered doing a chambered style piping build. I.E. before the muffler, all piping would be, say 2.5" and then right before the muffler, there would be a section what was 3.5" or something for only a foot with a 2.5 inside of it that would have a butterfly at the front to muffle the sound if closed. Never really got into the mechanics of it once I went single exit, but still an idea.
tl;dr: why butterfly??

To help those who dont understand what the flap valve does, here's Kris' car when running at WOT during a launch:

Might I add for starters that it's looking really, really good.

Well i blew up the motor..
Warning, Carnage below. (though it could have been worse)
Amazingly, there was really no damage to the cyl wall. There was some really fine scratches in it, but after a few passes with the hone they were completely removed.
Then i rebuilt it
Oh, and here is a front shot.

Drives beautifully. I havent gotten on it yet, still giving the bearings/rings a little bit of break in. If i get a chance to get enough miles on it and there is a trackday left yea, i plan on trying yet.
