We started exhaust development on the GT4 RS platform a few weeks ago, seems there will be some pretty serious gains to be had in all areas from just a rear silencer replacement. Weight saving, tone / quality of sound, power and torque.
Stock rear silencer is pretty heavily compromised. Super heavy and essentially an adapted 718 GT4 / Spyder unit and certainly not titanium like I’ve seen a few mention.
Factory manifolds and OPF / Link Pipes are a huge improvement in design over that of the non RS model but there’s still gains to be had in those areas too.
We’re planning to offer a number of rear silencer replacements as the first step then once our car arrives move onto manifolds / headers & Link Pipes.
I’ll be sure to post once we have something a little more exciting to share

Thanks for the update Jonny....I was expecting this. Same design as on the 4.0 9A2 engined models. One thing that would be nice is for those with Weissach the ability to reuse the Ti exhaust tips.....also, with all the sound going on on this car IMO a silenced and valved rear section is a must....keep us posted.

Otherwise, there would actually be a performance and weight benefit to the WP.

We will certainly test the option of being able to retain factory tips but most likely the performance gains that we can find will be all but removed by retaining them. With this in mind we have already designed a OEM like Titanium tip option to work with our design of rear silencer
Absolutely, that’s likely to be part of the reason for such compromises being made

And the very reason I couldn't see any benefit to getting a WP on that car. Save the $30k from the WP to get wheels and an exhaust aftermarket. And still have money left over for tires, brakes and track days.

My question is how will the interior sound differ from the WP with Carbon Fiber intake ducts and air box when compared to the plastic pieces in the non-WP car.
#5876
WP also requires you to upgrade the interior
#5877
There is at least one press review that says the sound and power are the same.
