With center and side delete, you are going to experience a lot of drone in your car. Be prepared to wear earplugs after a few miles.

Hope to see you at the track sometime.

Peter, great to hear from you. What are you driving these days?

Current set up has a bit of drone which i do not like. I assumed a valved side delete would help with this.

valved side delete and stock muffler, or a street header setup will get your some power and great sound with no drone....

Someone needs to make a side delete setup that also includes aero underbody plates to fill
the void left by the side muffler removal! Hint hint

We have the most comprehensive selection of exhaust components available for this platform, that means a ton of choice.

Manifolds, two side silencer bypass options, three centre bypass options, three race pipe options and three tip options for each model (we have 9 part numbers for our tips alone). All of which are modular and cross compatible with OEM components. That means that we have 26 possible configurations of JCR and JCR / OEM exhaust components (not including tip options as that just multiplies the configurations with little effect on overall result)

We're relatively new to this market however I think we have demonstrated that we mean business, we have done some catching up initially on the established platforms with many customers switching to JCR from other manufacturers, now we're leading the way developing and releasing products for the latest models (OPF GT3 RS / Speedster) and in a couple of weeks 718 GT4 / Spyder. I guess our success has not gone unnoticed by other companies, underhand dealings and questionable actions taken in attempts to smear our reputation and question our credibility but overall I think our customers shout louder than any of our competitors and their minions could.

The reason for the above is to explain why you might be seeing more JCR parts for sale on this forum than any other brand. The sheer quantity of our parts out there (we have sold 152 titanium race pipes since introducing the product in mid December 2018) and the fact that we have so much choice. The vast majority of JCR customers moving parts along then go on to purchase again from us (if they're not selling their cars) and then select either a more or less extreme option. Thats the beauty of offering so many different products and lets be honest, we all like to swap and change every once in a while.

I would love to do headers from GMG but I won’t risk my warranty on a $220k car.

GMG center bypass or CMS center bypass sound great and a nice option. CMS also now has new design with two separate tips. Both are megaphone design that give RS a deep burly sound as opposed to high raspy sound. CMS also has an X flow scavenging design.


JCR race pipe is too over the top for street use imho.

Just a bump for an informative thread.

there are other topics, which raise same questions but they have far less valuable info

Can't get anymore Ferrari sounding than this.

Is it full exhaust or catback only?

IPE offers both a full exhaust or a catback option. If you need more information on their exhaust reach me directly as we are their largest dealer in the world.

Why does the GT3 not make them?... and do any of these aftermarket exhausts bring these gurgles and pops into the picture?.. because if so I’ll stay stock wth GT3. Thanks for any clarification.
I read a while back that Porsche excluded the gurgle and pops on the GT3 for performance reasons. Something to do with the back pressure on throttle lift creates a performance disadvantage if immediately getting back on the throttle.

I do believe you are correct sir, and I've experienced both myself. No matter the exhaust setup pops/bangs aren't really present on the GT3 until the software is programmed to do so.

^^^ what he said. it’s in the tune. I’ve added it to my car. It’s not obnoxious like a vehicle with a turbo. I can close my valves with the exhaust button so it can be turned off as well.
