Milltek Non-Resonated GPF-Back Exhaust - Ineos Grenadier - Brushed Titanium Tips - SSXINE103

Direct fitment GPF-back exhaust system for Ineos Grenadier with B58 engine. OE particulate filter removal required.

The Grenadier is engineered for off-road capability, but its stock exhaust mutes the B58's natural character. This non-resonated GPF-back system reclaims the engine's full sonic signature while improving throttle response and driving dynamics. By bypassing the restrictive gasoline particulate filter (GPF), you restore the B58's intended exhaust flow and tone.

Construction & Fitment:

• Mandrel-bent T304L stainless steel piping throughout
• Hand-finished brushed titanium tips
• Non-resonated design for track/closed-course use
• Uses OEM hangers and mounting points
• GPF removal required; no cutting of OEM hardware

Every Grenadier system is tested for fitment precision and acoustic character before dispatch, ensuring OEM+ install quality and proven B58 sound engineering.

Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
