Im running a JCR on my WP car and covered 2,500 miles so far. You really cant go wrong


I'm interested in the JCR to fit on my RS WP after having one on my GT3..How are you finding it.?
Are you using the race version or the silenced race version? GPF car definitely sounds muted compared to the non-GPF car.
Hi,

I have both but running at the moment the Race Pipe

Is that too loud for day to day use? Don't want to ps off the neighbours! Is there any videos available of the race pipe on a GPF car?

Many thanks.

In terms of noise levels this selection gives you a good idea where everything sits in regards to dB

  • All readings recorded at Silverstone GP Circuit. Recorded on the national straight at the top of 4th gear with calibrated equipment and backed up with the circuits own recording equipment. Average of 5 readings result in the following.

JCR OPF RACE PIPE (Silenced) & JCR SILENCED TIPS - 94.8dB

JCR OPF RACE PIPE (Non Silenced) & JCR SILENCED TIPS - 96.8dB

100% OEM (OPF 2019 GT3 RS) - 96.9dB

JCR CENTRE BYPASS & JCR SILENCED TIPS (Non OPF 2018 GT3 RS) - 97.7dB

JCR OPF RACE PIPE (Silenced) - 97.8dB

100% OEM (Non OPF 2018 GT3 RS) - 98.2dB

JCR CENTRE BYPASS (Non OPF 2018 GT3 RS) - 100.8dB

JCR OPF RACE PIPE (Non Silenced) - 101.2dB

As all new cars are rev limited,static tests at 3/4 revs is out the window now days so totally pointless, I have not seen it done in a while.

Oulton still does static,
Goodwood still does static
Brands no doubt still does
Castle Combe still does static.

There are a fair few about that still do... but I personally only do unrestricted days or 105dB at the moment. Plenty about still.

well that would be good news as a static at 4k revs would be a low reading.

R i know its a public forum,but why do you feel compelled to jump to everybodys threads or questions.
I asked for a very good reason, i am not a numpty.Its no good if the car fails at 4k static,you cant even get the opportunity to drive by if that happens.Every hillclimb is also static,and as my car will end up on some climbs,i need to know.
And as there is not static readings its about as much use to me as a choc firegaurd.

Pretty sure those circuits that still carry out static noise tests follow them up throughout the day with drive-by.... Oulton used to do them as you were heading up 'Clay Hill' so it was always worth short shifting in a noisy car! Donnington often moved theirs around and I've been caught out a few times there over the years. Most cars will pass a static as they won't rev higher than 3-4000 rpm.
Other thing to consider on the drive-by tests is PSE valves open or closed. Some bypass pipes / exhausts retain the OE valves whilst others do away with the valve assemblies all together.
