Installing a $4,000 Exhaust on a $7,000 BMW 335i

The Problem with the Muffler Delete

• 💡 The original decision to cut off the muffler for a louder sound resulted in terrible interior drone and vibrations, making the car unpleasant to drive.
• ⚠️ The exhaust leak was evident from black soot around the cut-off muffler, indicating a poor seal.
• 🚗 The car was already equipped with a VRSF catless downpipe, which exacerbated the noise issues.

The GT Haus Meister shaft Exhaust System

• 🚀 A high-quality GT Haus Meister shaft exhaust system, costing approximately $4,000, was chosen to replace the faulty setup.
• 💰 This exhaust system represents a significant portion of the car's current value, estimated at about a third.
• ✨ The new system includes a rear muffler section and a Section 1 plus 2 mid-pipe, featuring stainless steel construction and impressive craftsmanship.

Challenges During Installation

• 🛠️ Removing the stock exhaust proved difficult due to its one-piece design and rusted Torx bolts, requiring extensive effort and multiple trips to the hardware store.
• 💥 Several tools, including an Alibaba-sourced Torx bit and a heavy-duty socket, were broken during the removal process.
• ⏳ The stock exhaust removal took approximately 4 hours, highlighting the challenges of working on older European cars.

Driving and Sound Experience

• 🔊 The initial drive with the open downpipe was extremely loud and unpleasant, with significant drone and vibrations.
• 🎶 Upon installation, the Meister shaft exhaust delivered a vastly improved sound, described as deep, satisfying, and comparable to a 2JZ or German inline-6.
• ✅ The new exhaust eliminated all interior rattles and vibrations, allowing for a quiet and comfortable cabin experience with windows up.

Unexpected Police Encounter

• 🚨 The car was pulled over by police due to a call about a stolen wallet containing an Air Tag, which had briefly connected to the vehicle.
• 🚓 Despite a thorough search, no stolen items were found, and the police determined the car was not involved.
• ⚠️ This incident highlights potential issues for modified vehicles, as they can sometimes be targeted by law enforcement.
