All these things are subjective . I feel like every exhaust has some drone in low rpm constant throttle. My assessment is BBI has higher pitch sound at high rpm and at 3 k it does drone a bit and tolerable to me. But i am used to that. Pretty much every exhaust i had 997.2 Gt3 Shark , Scuderia Capristo , 430 unplugged valves had some drone.

You are welcome to checkout my exhaust in person since you are not far from me. Pm me.

ipse dixit

Exactly.

Which is why if you go aftermarket, no reason to get another Timex.

side muffler bypass is the way to go. it is not more expensive than the final muffler bypass. on top of that it will not ruin the aero diffusing design that works with the oem muffler. cargraphic has the best design with a valve control that works with pse. I have them on order and will report back when I have them installed. akrapovic doesn't have anything in similar and their slip on muffler only saves 4 lbs from oem. the slip on costs 5k, and that's not a price efficient mod.

Awesome! I'm interested to hear your thoughts on the Cargraphic option. Please take photos!

If you are taking suggestions, I'd love to have something like that - sport button pushed, it's under 90db (to pass Laguna sound limit), sport button not pushed (default) - it's cup car sound (essential safety measure to avoid hitting a deer, for example).

That's what I was hoping to accomplish as well. After talked with EVOMS, it may never happen. You can create a solution using either the iPE or Cargraphic, but no one knows what it will sound like or how much power could potentially be lost.

Gotboost?

That sounds like a plan. Thanks!

no problem!

What's the price of the Cargraphic?

Found a lot of info on the Cargraphic systems here http://www.cargraphicts.com/en/produ...odels/991-gt3/

"but no one knows what it will sound like or how much power could potentially be lost"

power lost?!

what do you think about the sound of Cargraphic kit 6?

20 Horse power more ?!!? i'm skeptical

Akra is making the same claim of 20 hp on their Evolution Race setup, but it occurs at 3,950 RPM and 11 hp increase in peak hp at 8,000. I'm assuming there is some inefficiency in the stock setup that they both correct + the valves being gone.

I don't know exactly when stock valves open, but I thought it was 4,000? It seems to make some sense that the biggest delta without the valves is right before they would normally open.

Guys, sorry for the short response but I am at the St. Pete GP but also love going on RL when I have a break.

We have a Center Section with built in tips as well as a muffler delete system, which I will have my guys post about shortly.

Thanks,
