Available for auction is a top-of-the-line, full titanium exhaust bypass system and tip, designed to perfection for the Porsche 997/991 GT3/GT3RS models. Crafted with precision, the titanium piping has been expertly hand-cut and TIG welded to recreate the smooth exhaust flow typically achieved with mandrel bends. 
According to the seller, it was previously used for only about 3000 miles on a 997.2 GT3RS, this exhaust system is in impeccable condition, ready to take your Porsche's performance to new heights. Not only does it deliver a definitive sound that true enthusiasts crave, but it also retains the factory "sport mode" functionality, allowing you to toggle between aggressive performance and a more refined driving experience at your command. The exhaust has an original MSRP of over $2,000. 
This full titanium exhaust bypass system comes complete with all the necessary mounting hardware, making installation a breeze. Furthermore, its lightweight construction, weighing just 4.5 lbs, contributes to a reduced overall vehicle weight, resulting in improved handling and responsiveness. The buyer is responsible for shipping, handling, and fees.

I have confirmed with TopSpeed that the TopSpeed Titanium Bypass system retains the Porsche stock catalytic converter and mufflers. I hope that helps.
Hi responding to the question about the 'cats' and muffler......it is my understanding that both remain. Also, the car retains its 'sport mode' functionality. This system is still a 'current' TopSpeed exhaust system, so, if you wish, you may want to go to the TopSpeed website and ask TopSpeed directly so you can be 100% sure.
Do the cats stay in place ? Does this piece replace the muffler on the car or do you retain the muffler as well ?
Hello: I am the seller of Topspeed Titanium exhaust system. I acquired the Topspeed exhaust bypass system when I purchased a 997.2 GT3 RS, it was on the car when I purchased it. It had been installed on the car by the person that sold me the car. In his 2.5 years of ownership he put just under 3K miles on the car, I honestly don't know how many of the miles were logged with the Topspeed system, so, to be safe, I have assumed all 3K miles for the purposes of this listing, but, given, it looks to 'like new', so the mileage is likely less. My GT3 RS also came with the stock Porsche exhaust , which I had installed upon purchasing the car (just because I like my cars to be 100% stock). I sold my GT3 RS with the stock exhaust and retained the Topspeed exhaust system. I do not plan to buy another GT3, thus, I am selling the exhaust system.
I will gladly answer any questions to the best of my ability, but I am not a mechanic. The Topspeed titanium exhaust system is presently in Ponte Vedra Beach Fl, while I am not there, if there is interest to physically view it, I can arrange for it to be shown.
