JCR back box , who’s done it, would you do it again ? The car guys seemed to think it wasn’t really worth the £5k price tag. I know when coupled with the manifolds it sounds insane , but that’s 8/9k of a job.
It’s a nice sounding exhaust. Is overpriced but sounds nice. People have also opted for BCF.MannyLon said:

It’s a nice sounding exhaust. Is overpriced but sounds nice. People have also opted for BCF.As I understand it because the valves close at circa 2k rpm and then open fully circa 5k rpm even with the JCR Lichfield or BCF options the sound track issue is more related to the valves than the actual stock exhaust
Can anyone confirm if this is the main issue before spending the serious money on a replacement box
There's lots of info in a couple of exhaust threads on here.
Valve controller with stock exhaust is louder but has drone in my experience. Standard exhaust is also quite restrictive, and does not mix cylinder banks unlike some replacements which are x-pipe designs.
JCR with standard valve controls seems to be the best minimal drone replacement but it's very expensive.
I have standard valve controls and a Ninemeister silencer. The volume and tone is perfect for me, there's a touch of drone between 2k-3k revs but it's tolerable, even more so if you don't press the PSE button so the exhaust valves stay shut and the valved intake resonator system that's piped into the cabin stays closed.

I have the free mod. on mine. 2 grub screws in the vac lines to the solenoids. I am assuming that this is the same as installing a vac line controller a la Cartographics, just without the adjustability. In my experience It is much better as it keeps the engine note nice and linear with throttle progression which makes it a much nicer drive. The actual exhaust note is nowhere near as nice as a non particulate filtered car as you loose all the harmonics as you go up and down the rev range. However without spending a bean it’s way better than standard and very easily reversed.
I have heard various JCR equipped cars and they sound awesome but insanely loud which rather defeats the point for me. I want nice noises without unnecessary attention.

Have you tried just doing one vacuum line, its a good bit less harsh and the PSE button still works for what good it is.Cannot see the point in speccing PSE as when you press it stationary it will open the valves but close them as soon as you pull off, will open valves regardless if you have it switched on or off at around 3k revs.Always liked the quad pipes against the 2 as well.I have heard various JCR equipped cars and they sound awesome but insanely loud which rather defeats the point for me.

Do you have one? Has anyone tried the Lichfield exhaust? £3.5 including Vat

Anyone found a pic of a real life GT4 or Spyder in Shark Blue yet? I have seen plenty of GT3s but no 718s. Thanks in advance.
This is Voodoo which is very similar… although these photos are too light I think compared to other voodoo pics I’ve seen.AdamGT4 said:

This is my Voodoo Spyder with the Shark Blue colour plate borrowed from a Porsche Dealers samples Basically as you can see Shark is just the new name for Voodoo - Only Porsche could pull a stunt like this and get away with it
