Show original supplier description
The HKS Legamax Hi-Power Dual cat-back exhaust system (part number 31013-BG002) is engineered for enhanced street performance, specifically for the 2007-2008 BMW 335i Sedan models. Constructed from durable SUS304 stainless steel, this exhaust system features polished dual tips with a titanium finish, each measuring 97mm in diameter. The main piping diameter is 65mm, designed to optimize exhaust flow and produce a more aggressive sound. It is important to note that this specific exhaust system is designed exclusively for the 2007-2008 BMW 335i Sedan (E90 chassis with N54 engine). It will not fit other chassis variations, including E92 coupes or xi (all-wheel drive) models. Attempts to install this system on models with a transfer case bracket, such as the 335xi, may result in clearance issues with the mid-pipes, rendering it incompatible.
