Thought it was about time that I get a thread started. A little different to the usual product launches, this time more of a thread to keep updated on the progress of the development.
Now we have some good content to share I thought it was time to make a start!
Anyone who’s been following our social media will have seen that we have been working on the latest OPF (particulate filter) exhaust systems installed on the latest batch 2 GT3 RS and Speedster.
First up we removed the factory OPF exhaust system and began taking measurements and gathering further understanding of the factory installed system
OEM OPF exhaust system Factory header complete with cats and OPF Highly restrictive path the gassed are forced to take upon exit of the OPF The first mock up of how things might look
We first wanted to produce a direct replacement titanium tip option for those owners who wish to simply upgrade their factory installed tips with a high quality titanium part.
Porsche dropped the titanium tips on the latest GT3 RS so we thought it was right to correct that!

And the finished result came out great!

We then went on to make a start on the design of the huge Vband / bend which allows direct fitment to the factory OPF, forming a third of the exhaust system.

The factory exhaust integrates the secondary OPF bung to allow the car to take readings to determine the correct and proper function of the OPF at all times.
We integrate this into the bend, in the factory location with a 3D printed titanium bung. Again, allowing easy direct fitment, perfect as per OEM.

Now the money shots!
The images below show the JCR Titanium Silenced OPF Race Pipe. We will also be releasing a non silenced version at the same time to allow owners to choose the appropriate level of aggression they desire!
The new system uses the exact same centre merge / tip flange as per our pre OPF race pipes which not only means that signature JCR sound but also opens up a whole host of tip options, including our silenced tips for those keen track drivers with dB limits!
I’ll be sure to keep this post up to date with the latest. Dyno testing next week and a ton of data will be shared!
any impressions on how it sounds relative to the pre-OPF cars?
We will be releasing videos of both the silenced and non silenced versions when we have the car on the dyno next week. Coming soon!

For those who wish to delete the OPF we will have an adapted version of our current Inconel race manifolds which will allow deletion of the OPF and cats.
This system is intended for those who wish to retain their factory OPF headers

No check engine lights or ECU work required?
Ive read North America may have a filter removed, will that have any effect you’re aware of?
Will you produce a valved version to control exhaust volume?
Lastly what will it cost?
I look forward to the testing results and sound clips.
1. Direct replacement, no requirement to tune and no CEL.
2. I believe the filter will be replaced with some kind of restrictor / filter however the design of the headers / OPF will be dimensionally the same meaning that this system will still be direct fit. It’s likely that we will just provide a secondary OPF pressure sensor bung as the US cars will not have this fixing.
3. Yes, a Valved version will be coming before year end. Personally I don’t believe it’s necessary to have valves with this particular set up.
4. Costing will be released as soon as we have gathered all of the data and release both the non silenced and silenced OPF race pipes in the coming few weeks

Why do you think no Valves will be required?
do you think it’s louder than the non OPF Center Bypass
JCR got banned on here (I don’t know why and they don’t know either) if you have questions you want to ask DM them on Instagram (@jcr_porsche) or via Mail they respond very quick.
