DescriptionThe whole story▼
Shedding 5.5 kg from the stock exhaust system, the Spark Exhaust MotoGP Slip-On with CAT replacement pipe transforms the Kawasaki ZX-10 R/RR into a sharper, more responsive machine — whether you're chasing lap times on track or demanding instant throttle response on the road. Handcrafted in Italy from full titanium, part number GKA8816T is a complete 3/4 system that replaces both the catalytic converter and the silencer in a single, precision-engineered package.
Key Features
- 3/4 system comprising a Spark MotoGP slip-on silencer and a dedicated CAT replacement pipe, delivering measurably improved exhaust flow and throttle response
- Titanium header pipe and titanium silencer body — exceptionally light, high-temperature resistant, and built to last a lifetime of hard use
- Carbon end cap adds structural rigidity while giving the silencer a purposeful, race-derived aesthetic
- Removable DB-Killer lets you tailor the sound level: compliant for road use with it fitted, or producing an aggressive 105 dB at 5,500 rpm without it
- Weight saving of 5.5 kg versus the OEM system (from 7.0 kg down to just 1.5 kg), with direct benefits to handling dynamics, acceleration, and overall chassis balance
- Made in Italy — all exhaust springs and the complete mounting kit are included in the box
Performance & Construction
The CAT replacement pipe eliminates the restrictive standard catalytic converter, freeing the exhaust gases to flow at maximum velocity from the headers rearward. Paired with the MotoGP-inspired titanium silencer, the result is an exhaust note and a mid-to-top-end responsiveness that no slip-on alone can match. Titanium was chosen not as a styling exercise but for its outstanding strength-to-weight ratio and its ability to withstand the sustained heat generated by a high-revving inline-four like the ZX-10 R powerplant.
The carbon fibre end cap is more than a visual detail — it resists heat and vibration at the outlet where temperatures and mechanical stress are highest. Every component is assembled in Spark's Italian facility to tolerances that ensure a rattle-free, leak-free fit from the first ride.
Road & Track Versatility
The removable DB-Killer is the system's practical masterstroke. Slide it in for everyday riding or noise-regulated track days; pull it out when the session demands maximum acoustic presence and every last fraction of performance. Spark recommends pairing this system with a dedicated race map or a professional dyno tune to extract the full performance gain that the unrestricted exhaust flow makes possible.

- Kawasaki ZX-10 R — 2016, 2017, 2018, 2019, 2020
