Product Description

The Borla 140505 is a Touring cat-back exhaust system designed specifically for the BMW 3.0L inline-six found in the 2006 325i, 325xi and 2007-2011 328i, 328xi, spanning the E90 sedan and E91 chassis in both RWD and AWD configurations. The system features Borla's mellow Touring sound level with no drone inside the vehicle, starting with dual 2.25-inch diameter pipes that merge into a single 2.5-inch pipe before exiting through dual 2.25-inch tail pipes.

Single 3.19-inch round polished T-304 stainless steel tips finish each tail pipe with a rolled, angle-cut design for a clean, upscale look. Built from premium T-304 stainless steel, this system uses Borla's patented straight-through and multi-core technology to unleash hidden horsepower while increasing exhaust velocity for gains in power, driving excitement, and fuel economy.

This exhaust is intended for 325i and 328i owners across automatic and manual transmissions who want a refined, understated sound upgrade rather than an aggressive, attention-grabbing tone. Ultra-smooth mandrel bends and precision CNC manufacturing ensure an accurate, direct fit; backed by Borla's Million Mile Warranty.
