There is a new Jcr race exhaust, I am guessing no valve, no center. i have heard the red gt3rs on your website, what exhaust is on that car? Does it maintain the stock header? does it have valves? thanks
More information will be coming soon for the JCR Titanium Race Pipe but essentially no valves no silencers mating up to the OEM headers (or) aftermarket headers which feature OEM style flange.

There's lots of talk on center bypass pipes here but very little on side muffler bypass pipes. Remember, side muffler bypass pipes have other big benefits to consider versus center bypass pipes in addition to the sound. Ditching the side mufflers net about 40lbs of weight loss off the back of the car, and rid you of significant heat soak just a few inches off the rear tires. Especially for guys tracking their cars, this is a huge plus. Combine it with a lithium ion battery (the Rennlist-loved Anti-Gravity version for example) and you just saved yourself near 80lbs of weight for about $2k. That is one heck of a ROI considering the Weissach Package nets you 38lbs for $31k.
Sound between the center and side muffler bypass pipes are different and can vary a bit depending on design. I know them quite well and would be happy to spend some time chatting with you about them to help you make an educated decision. My cell is 484 883 6197, text or call me any time.
For your consideration, here are some photos of our center muffler bypass pipe and side muffler bypass pipes. Our valved version of the side muffler bypass pipes will be released shortly, as well as a detailed write up I am working on comparing the center and side muffler bypass pipes for future reference to fellow RL members.

Anyone install one yet and happy with the results? I've had sharkwerks bypass on my last two 2 gt3's and was happy with the results. Would like something easy to install. Thanks
To answer the OP, we have had dozens of installs in our shop and plenty of others of our walls that have thoroughly enjoyed the exhaust. Installation is fairly simple with some experience also.

For the 991 GT3/RS platform race headers or full catback valved systems are the best option.
Full catback system means side bypass with rear muffled exhaust/bypass, with a valve.
I find it hilarious that so many members/sponsors go back and forth about which rear bypass is best. None are best. They all essentially do the same thing.

How much less sound (loud) would the center bypass, non silenced, and the side deletes (with valves) be, compared to this. as this is 2 pipes straight out there back.

When valves are open, essentially very similar (however our race pipe features different diameter pipe work which does add some volume) but obviously with the valved side deletes you have the option to close valves and although you have mentioned a comparison with the non silenced centre even with no silencers the smaller diameter pipe work does take a big portion of volume away.
The race pipe is really for those who are comfortable with big volume all the time in order to gain maximum performance and run the lightest package possible.
