R44 BMW M3/M4 Race Exhaust Cat-Back System In Titanium - Carbon tips (G80/G82/G83)
The R44 Performance G80 M3 and G82 M4 Exhaust System! Have you been wanting some noise for your M3 or M4? Well, we have the only solution!
Welcoming R44 Performance's latest addition to their G8X programme.
After months of development and testing on the S58 platform, we are pleased to release the full Cat-Back system to the market. The R44 System removes the Secondary Cats, OPF Filters on EU Cars (See notes below) and mid silencer. This reduces restrictions and allows a huge amount of extra flow through the exhaust system, resulting in an increase in BHP.
Creating the perfect soundtrack - We have fitted two bullet silencers mid-pipe to refine the note and added two valves. The valve system works off the OE BMW system. The pipe design at the rear of the car allows air to flow straight through when the valves open as well as through the backbox. Providing a rich tone releasing the hidden burbles and cracks. Check @R44Performance on Socials for Videos and below for a fitting / demo video.
Wanting to tone down the noise? Close the valves and the airflow will be reduced and pushed into the resonator box.
OPF EU CARS - We have been using an OPF Delete connector that simulates OPF filter readings. Our pipework has all OPF pipe connections to allow gas readings, paired with an OPF delete connection results in no Engine Management lights or incorrect readings. - Please opt for the OPF delete Cable when adding the product to your Basket
