Starting a new thread since my other one can't be edited for some reason.  Ran on my RS for about 6 weeks.before i decided to go louder.  Really nice piece and super light, good for folks wanting more noise but not enough to wake the neighbors.


JCR Ti Center delete, used for about 1200 miles.  Very clean and sounds great. Comes with some Ti tips as well. One of the clamps broke when removing but i'm going to order another one shortly.  I think the stock ones can just be reused.  From the 991.1 GT3 to the latest 991.2 GT3 RS, the factory exhaust system is somewhat a compromised piece. Porsche have engineered an exhaust system which will meet the requirements of each and every customer, from the every day driver to the most avid track day fan.

The JCR Exhaust line is modular in its construction, meaning that when combined with factory components our products allow for an impressive number of permutations. We offer a number of material choices, from high grade T321 Stainless Steel through to the lightest weight motorsport grade Titanium. This means that no matter what you're looking to achieve our line of Exhaust components will surely be able to fit your needs.

Light Weight

Due to the 100% Titanium construction the JCR Centre Bypass knocks off an impressive amount of weight from the rear end - Any weight reduction is good news however reducing weight rearward of the 911's rear axle can yield huge improvements in handling balance too. This truly is a win win modification.

Race Car Sound

The JCR Titanium exhaust line has been carefully developed to enhance the tone of the 3.8 and 4.0 flat 6 with the focus on creating the most aggressive results at full throttle while maintaining a reasonable level at partial throttle and curising RPM's. The benefit of the 100% Titanium construction is the natural resonance which occurs whilst using this material, a hard edged tone reminiscent of the latest mid-engined 991 RSR race cars.

Power Increase

Every component of the JCR Titanium Exhaust line is guaranteed to improve HP & TQ with varying results dependent on the combination of parts. Our most extreme free flowing system will see gains in the mid 30HP along with great improvements in engine response and mid range torque.
