2007-2009 Porsche 997 Turbo Marski X-Design sport exhaust 4 Muffler Version

This was installed on my 2009 911 Turbo for a while until I was rear ended, the exhaust was bent in a few places but still remained fully functional.  There are no cracks or breaks on the mounting points or anywhere else on the exhaust.  I ended up going with a more aggressive exhaust and now selling this one.  Comes exactly as pictured and discounted due to condition.  

Again, this exhaust is still very much functional and will mount to your vehicle without a problem.  As pictured.  

Retail for this was about $2800 delivered to me originally.


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.
