HKSTUDIE Exhaust for BMW M3/M4 G80/G81/G82 Comp

• Tail tips with a thick-walled, slash-cut design, a blasted matte-gloss finish, and sound-deadening inner slits, styled after the BMW 3.0 CSL.
• The middle muffler is removed from the layout, and the sound is tuned using frequency analysis for a refined but strong tone.
• Stated to meet UN ECE-R51.03 Phase 2 noise limits and Japanese vehicle inspection requirements for daily use.
• Claims up to 35% lower exhaust back-pressure than the OEM muffler, with up to 5 kW and 15 Nm gains from the optimized layout and unrestricted main muffler.

Fitment: BMW M3 G80 (2021-2026); BMW M4 G82/G83 (2021-2026)
