Our trademark perfect x pipe geometry, harmonically tuned silencers, Inconel 625, and our propriety acoustic silencer packing materials result in a system that has become famous for that perfect sound. Zero drone, and a raised pitch raucious incendiary howl in higher rpms and hard throttle.

The Sound

Capitalising on the design innovations and success of our 996 and 997 range, the starting point for designing the 991 GT2RS exhaust had been set high. Our trademark perfect x pipe geometry, harmonically tuned silencers, Inconel 625, and our propriety acoustic silencer packing materials result in a system that has become famous for that perfect sound. Zero drone, and a raised pitch raucious incendiary howl in higher rpms and hard throttle. Utilising the stock valvetronic vacuum system, we were able to incorporate our propriety valvetronic silencers, allowing an even stealthier ride on valve closed, and a more aggressive sound on valve open.

Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!

Great Value heat gear material with high neck collar and loose fitting
Color: Black, Size: X-Large
My husband has been looking for mock neck shirts that are comparable to UA heat gear material but that are short sleeve and fit loose to wear under his work uniform. These seemed to have been a good soft quality option and the price is is great.
