Need a  Custom made 997 turbo® exhaust?

When it comes to 997 turbo® exhaust ,we at Markski tuning are proud to offer our 997 turbo® exhaust – X-Design sport exhaust which is all hand crafted 2(4 optional) muffler exhaust system for the 997TT® and manufactured in house per order. Since 2007, we spent countless of hours developing a unique muffler sound by testing various muffler cores along with muffler packing materials. Unlike majority of the 997 turbo exhausts on the market, we make the muffler from scratch in house along with our X design cross over which is a true X perfectly designed and welded. We do not use any over the counter pre made components. Stainless steel V bands and .5″ thick custom cnc machined flanges are welded to catalytic converters. We offer this system as catless, or with 100, or 200 cell catalytic converters. The system is TIG welded and ported inside for maximum flow. We have a series of exhaust tips to choose from be it oem fit, dual 3″, polished, coated, titanium look, and even mini resonators inside the tips. During the final stage of production we hand polish to mirror finish. A 3″ and  2.5″ OD tubing is available pr a combination of both.  Do not get fooled by cheap imitations with poor quality and cheap muffler components. Not to mention, the catalytic converters used are very important in the performance of the exhaust. We use only US made high quality 100 and 200 cell components.  The complete 3″ exhaust weighs only 28 lbs. with 100 cell cats. Our X design exhausts have made astonishing 1100hp.

Dyno Graphs

Due to the free flowing 3′ exhaust the dyno clearly shows how the exhaust reduced back pressure at higher rpms as the Hp increases.
