991 GT3s are delivered with paper filters from the factory. As far as paper filters go, they are actually quite nice. However, they are not serviceable and BMC RS filters are.

Here you can see the difference between the two. Not only are the BMC RS filters serviceable, they will flow more air directly into the throttle body. If you would like a set for your 991 GT3 they’re available for $225. Call or email to order – (612) 547-9311 or info@311RS.com

As for the Akrapovic Race exhaust system, it’s trick – 49lbs of weight is removed from the rear of the car and in combination with a tune (EvoMS in this case), the car makes an additional ~40whp. We’d like to have the car on the dyno prior to BIR next weekend, so we’ll wait to confirm the power output until then.

And here is a look behind the veil of a 311RS GT3. Each upgrade is key to the final setup of the car. Plus, just look at those meats. The car is running 325/30/19 Michelin Sport Cup 2s on a set of 19×12.5 BBS E88s.
