Default Exhaust options for GT3/Speedster with ITBS and particulate filters
Hi guys, I’m looking to explore options to install a after market exhaust on my Speedster but currently I’m not too sure due to the new ITBs and particulate filters. Previously I never had to tune the ECU When installing headers and exhaust on any GT3/GT3RS, has anyone had any experience with this ?

Dundon and JCR both have options for your car (and maybe others)

We have two options, released a little time ago now with many happy customers.

No tune required for the exhaust, simple direct replacement install.

Red car 2019 GT3 RS with OPF / Grey car 2019 GT3 RS with JCR Exhaust

Thats correct, we have a silenced and non silenced version, direct replacement for the factory rear silencer. Quick easy install, weight reduction power and torque increase plus a fantastic sound along with no chance of CEL or change in emissions.

We’re set to release our OPF delete race cat manifolds in the coming weeks for this platform too.

Also no, we will have a solution that requires no tune. Deleting the OPF will affect emissions however but our manifolds include 200cel race cats

Will that be enough to pass emissions? What is the weight saving from deleting the OPF? I understand those are rather heavy? Thanks.

They're really not too heavy. Our OPF delete pipes are made from Titanium - Total weight saving will be around 10kg vs OEM OPF pipes

nice! Good to know. They say the opf replaced the aide mufflers on the speedster. So opf appear much lighter than side muffler on 991

Exactly that, the OPF present on the Speedster are part of the cats / headers. The exhaust system is now made up of 3 main components rather than the previous 5 components.
