034 Motorsport - Audi B9 RS5 2.9TT Stainless Steel Downpipes - 034-105-4046

The 034 Motorsport Stainless Steel Racing Catalyst Set for B9 Audi RS5 is designed as a drop-in replacement for the restrictive factory catalytic converters. The Stainless Steel Racing Catalyst Set offers increased horsepower and torque throughout the powerband, reduced turbocharger lag, improved throttle response, and enhanced exhaust note.

This complete drop-in solution includes an integrated v-band flange at the turbine outlets, integrated oxygen sensor bung after the catalysts, integrated 3-bolt downpipe flanges, and a complete gasket/hardware kit to allow for precise fitment and ease of installation. The Stainless Steel Racing Catalyst for B9 Audi RS5 vehicles is constructed from 304 stainless steel for maximum durability and corrosion resistance, is TIG-welded and back purged, and includes an integrated OE style heat isolation barrier to minimize exhaust heat transferred into the engine bay.

        Impressive Sound Deadening Solution with Enhanced Audio Quality
        Model: NewSLS50_52
        I recently purchased the Siless 50 mil (1.3mm) 52 sqft Car Sound Deadening mat, and I am delighted with the results it has delivered. Right from the start, I was impressed with the packaging, which ensured the product arrived in perfect condition. One of the standout features of this sound deadening mat is its ease of use. It was a breeze to cut and modify according to my specific needs. Whether I needed to cover specific areas or customize the size, the mat accommodated my requirements effortlessly. This flexibility made the installation process a breeze. The Siless Sound Deadening mat has proven to be highly effective in reducing outside noise within my vehicle. With just a half cabin install, I noticed a significant reduction of approximately 10 decibels, making my driving experience much quieter and more comfortable. The mat acted as a reliable barrier against external noise, allowing me to enjoy a more peaceful ride. Furthermore, the sound quality from my vehicle's audio system experienced a noticeable improvement. The Siless mat effectively dampened vibrations and minimized resonance, resulting in cleaner and more refined audio output. The mat's thickness of 50 mil (1.3mm) ensures optimal sound absorption, contributing to its effectiveness in creating a quieter and more enjoyable driving environment. I can now appreciate the full range of tones and enjoy a more immersive music experience during my drives. Overall, I highly recommend the Siless 50 mil Car Sound Deadening mat for anyone seeking a reliable and effective solution to reduce noise and enhance audio quality in their vehicle. The easy cutting and modifying process, along with the excellent packaging, contribute to a seamless installation experience. With a significant reduction in outside noise and an improvement in sound system performance, this sound deadening mat has exceeded my expectations.

        Good quality sound deadener at a good price.
        Model: NewSLS50_52
        Quality sound deadening that adheres to body panels well. You can easily hear the vibration reduction after just the first piece by tapping on the body panel before and after.
