Show original supplier description
The Black Market Raceworks BMR 3.5" Cat Back Exhaust is engineered to deliver exceptional sound and performance for the 2008-2013 BMW 135i models equipped with the N54 or N55 3.0L inline-six engines. Constructed from premium T304 stainless steel, this system features a robust 3.5" diameter for optimal exhaust flow. It boasts distinctive 3.5" dual slash-cut tips and a strategically mid-mounted muffler to enhance the exhaust note. The clamps are also 3.5" to ensure a secure and leak-free installation. This cat-back exhaust system is noted for being one of the largest and best-sounding options available for the 135i. Compatibility extends to both twin-turbo and single-turbo configurations of the 135i. For enhanced customization, an X-Brace spacer is available for purchase separately. Additionally, each section of the exhaust can be upgraded to titanium for further weight reduction and aesthetic appeal. It is important to note that this system is a special order item with a build time of 4 to 8 weeks. This cat-back exhaust does not fit models equipped with the M series rear valance.
