Any dyno graphs on your exhaust Charles for the 6? How much weight loss total from stock? The whole kit includes muffs/headers and what about the cats? It's great that the 6 still have interest vs the other variants. It's the perfect imperfection. Mike

I had dyno before exhaust. Will have to dig up. 367 to wheels peak with dynojet for time trials. Then 2 yrs later 380 peak whp dynojet. Both with Charles exhaust. 367 after refresh of engine. (Machine heads and valve guides) Then after 2-3 yrs I guess engine gets broken in got 380. Gonna repeat. Would like a lower number to compete. Leak down now like 2-3%. Not bad for old engine. Only 31k miles. Mk

That video doesn't demonstrate the limits of the 6-3 as much as it does you are a more experienced driver than the person wheeling that 991-3. Nice driving.

Here's the dyno's for the system...
Blue is Center Exit, Green is Dual Exit, Both catless
Charles is making a few of the dual exit right now, so good time to grab one if you're interested.

Hey Mike, it's Suneal -- hope all is well. Nice wheeling! I joined the 6GT3 club a few months back, bought the silver car from Gavin.
Let me know when you're at Sebring next. Had the car out there for the first time with Chin yesterday, video of one session before gopro issues below, best lap in this one is after ~4:45 in.
BF Goodrich Rival S 245 F / 315 R, Exe-Tc single adjustable dampers, full monoball suspension, 997 GT3 Cup headers w/o cats going straight into factory 997 GT3 center muffler, 997 RS 4.0 LWFW/clutch, Pagid RS29 and GiroDiscs (both very thin, needing replacement now).
Cup front splitter came off on the way to the track (rodents grrr). Car will be more confident with that and 4 or 8deg rear wing shims I think, esp in Bishops.

nice ice smooth driving Suneal. Sure. Will let you know! Haven't ran with another 6-3 in awhile. Have Gavin rivet that cup splitter in. Check mine out.
