Sport Exhaust Rear Silencer Stainless Steel 63mm EG Certified

The Bastuck Sport Exhaust is a rear silencer upgrade for the 07+ BMW 3 Series E90/E91 325i/330i, designed to enhance both the vehicle's sound and aesthetics. This system focuses on the rear silencer for an effective and often uncomplicated way to achieve a unique, sporty sound without necessarily replacing the entire exhaust system. It features a precisely adapted pipe diameter of 63 mm, which contributes to a deeper, more resonant exhaust note. The optimized flow is intended to improve response and enhance the overall driving experience. This rear silencer comes with EG certification, ensuring it complies with legal regulations for road use. Installation is described as straightforward with a suitable adapter. However, it's important to note specific fitment caveats: The complete system cannot be used on 325i/330i models built after February 2007; on these vehicles, only the final silencer can be installed using the connecting pipe BMWE90-AD6. Additionally, Quattro systems are only compatible with vehicles without an M rear apron, and require the rear apron extension BMWE90-HE1.
