E46 M3 CSL-style Carbon Exhaust Tips for Cobra Sport 3" Systems, Part No. CST-4SLASH

For E46 M3 owners running a Cobra Sport 3" cat-back: these aren’t generic ‘Mustang tips’ - they’re CSL-inspired, slash-cut, 4" carbon fibre tips engineered to match the diameter, exit angle and visual weight of the original M3 CSL rear diffuser treatment.

• Fitment is precise: designed for Cobra Sport 3" systems only - not for stock, 2.5", or non-Cobra 3" setups
• Heat-rated construction: stainless steel inner sleeve + aerospace-grade carbon weave - survives sustained track-day duty, not just fast-road show-and-go
• Stage 1 to track day ready: pairs cleanly with decat downpipes, N54/N55 tuning, or full OEM+ builds where visual cohesion matters
