QD Stainless Steel Decat Headers BMW R1300GS 2023-25

Upgrade your BMW R1300GS with the QD Decat Collector Pipe

Engineered to deliver exceptional performance gains, reduced temperatures, and a refined exhaust tone. Constructed from premium stainless steel, this collector system incorporates a central pre-silencer that optimises gas flow while effectively managing noise levels.

Thanks to precise internal flow analysis, the QD Decat Collector achieves an impressive power increase of +7.1 Hp alongside a significant reduction in exhaust temperatures. The system includes a connection for the third lambda probe and an integrated valve fully compatible with the standard servo motor, ensuring flawless operation with your bike’s electronics.

Its modular design allows fitment with the original exhaust or any aftermarket silencer designed to work with standard manifolds, providing maximum flexibility. The system also offers a substantial weight saving of 6 kg over the original configuration.
