Dinan Rear Section Exhaust Upgrade for BMW 1 Series 135i and 135is E82 E88 2008 to 2013
Give your 1 Series the sound and response it deserves with Dinan’s premium stainless rear silencer system. This bolt-on back box enhances gas flow for sharper throttle feel and a richer, deeper tone that stays calm on a steady cruise yet comes alive when you press on. If you are after a quality stainless rear muffler for a 135i or 135is that looks factory plus and fits perfectly, this is the smart choice.
What makes this Dinan rear section stand out
- Improved flow characteristics for genuine responsiveness compared to the factory back box.
- Refined soundtrack at motorway speeds with an assertive growl under load for an engaging drive.
- Constructed entirely from corrosion-resistant stainless steel for durability in UK conditions.
- Direct replacement using OEM mounting points for a straightforward installation.
- Reduced mass versus stock for a more agile feel.
- Twin 3.5 in polished tailpipes deliver a tasteful, motorsport-inspired finish that fills the 1 Series valance properly.
