Valves open for the acceleration videos, the valves open regardless at WOT

Cruising RPM the valves are closed and the sound is very sensible, non intrusive, the best of both worlds.

The silenced titanium tips we are just finalising today in fact, ill have them live on the site tomorrow all being well!

No changes to the emissions devices, rear silencer replacement only so no issues with legality.

The exhaust above is just the JCR Titanium Valved Race Pipe, all factory emissions devices remain. 100% OEM headers, Cats and OPF's in place.

Nice video! Since you've reached 5th gear on the video and considering the short gearing (!) on these cars I'm sure everything was done respecting the speed limit!!

Cant wait to see the whole system together with some comparo vids with stock setup!

Keep up the good work. You make the long wait for the car a bit easier!

Thankfully no speed limits on an airfield

Glad you like the video, more coming

I see that you are still making improvements on the design of this. Comparing the pictures at the beginning of this thread with the actual pictures on the website it shows that you added some kind of shield on the upper piping. Were there some heat issues with original design?

Considering that’s mufflerless but (hard to tell for sure of course) still sounds streetable, I can only guess that the particulate filters are the source of considerable sound attenuation.

Absolutely right, the OPF matrix is a very efficient silencer in its own right.

So I was just on your website and do I see that the price for your 718 GT4 & Spyder - TITANIUM VALVED RACE PIPE has gone from £3495.00 GBP to £4145 GBP?

Or does this have something to do with 'silenced' versus 'non-silenced'? Can you explain the differences?

Thanks!

Hey,

The pricing posted on the site and the forum was introductory pricing for the Non Silenced Valved Race Pipe with Titanium Tips. The first 20 orders placed were entitled to this price

Normal price for this combination is now £3645.00 GBP - Link below

https://www.jcr-developments.com/por...egaphone-tips)

Since then we have also released our Inconel Rolled Tip option (£150.00 GBP more than Titanium Tips)



Plus we now have the Silenced version of the Valved Race Pipe available too.

So now 4 products in total with different pricing for each. Plus ceramic coating options for tips.

Titanium OPF Delete Pipes (three versions) and Inconel Race Manifolds coming soon too!

I’ll update the main post tomorrow to make this more obvious when visiting the thread

Sounds like an interesting option. Costly proposition in this commonwealth nation, that would be about $6700 + taxes and shipping and duty if any. Probably around $8000 CAD delivered not incl duty if any.

Maybe I just missed it, but is it "soon" yet?

Plenty in this video, I think you'll agree sounds better than anything else out there.

The pops and crackles are audibly there plus I challenge anyone to tell me this doesn't now sound GT3 esque!
