BMW 1 Series M135i F20 F21 Cat Back Sports Exhaust by Cobra Sport

Give your M135i the sound and look it deserves. This Cobra Sport cat back system replaces the centre and rear sections with free-flowing 76.2 mm 3 inch stainless pipework and finishes with stunning twin 88.9 mm 3.5 inch tailpipes. It is a direct bolt-on upgrade that fits neatly to factory mounting points, sharpens response and delivers a deeper, richer tone on the BMW 1 Series hatchback. Suitable for both rear-wheel-drive and xDrive models from 2011 to 2015.

• Cat back layout from the catalyst back for improved flow and soundtrack
• 3 inch 76.2 mm T304 stainless steel pipework with smooth mandrel bends

• Twin 3.5 inch 88.9 mm tailpipes in multiple finishes for that OEM plus look
• Direct fit with clamps and gaskets included
• Covered by Cobra Sport Lifetime Warranty non-transferable

Choose your volume level
