Had a pair of white shark'd 991 GT3's spotted in Norcal this Friday. First up this nicely-optioned new white 2014 991 GT3 drops by for a tasty sharkification via our Shark Werks GT3 Sport exhaust. Just like all GT3 models that came before it the 991 is no different, too many mufflers that need to be uncorked...
In she comes:

Black wheels, ceramics and those new tires:

Nothing to see move along!

This is what we're here for (and notice the engine cover). Three mufflers deep and we're going to remove the center for some improved tunes:

With the 991 GT3 no bumper removal is required and the installation can be done within an hour:

Off come the tips first:

Loosen the center exhaust factory clamps/hardware and it pulls right out:

Just a quick step onto the scales for the factory one:

And the Shark Werks exhaust (12.2 pound saving off the bum):

Our exhaust is designed to re-use the rather attractive factory tips (or our racier ones if you like). You'd never know the car has been sharkafied until you hit that exhaust valve switch:

This one is also nicely optioned with some red stitching, carbon and other treats:

Like the other 991s, the GT3 comes with three mufflers - one tucked behind each rear tire (see pic below) and a center muffler in the back. The sport button effects the side mufflers. The Sharkwerks exhaust replaces the center muffler only.

oh didn't know that. I had a 997 gt3 and I pulled the valve solenoid so it would always stay open. sounded nice but got the dreaded drone at 65 mph.

Hahah....
Oh oh!

Cheers and we did this primarily for sound. Similar set ups on the .7gt3 did yield 5hp or so but...

interesting about the new engine undertray ... must clean up the undercar airflow at the back, but also increase engine temps?
