VAC by Fabspeed - E46 M3 Stainless Steel Rasp Suppression Pipe (Section 1)

Purchase VAC by Fabspeed - E46 M3 Stainless Steel Rasp Suppression Pipe (Section 1)

Don't let your M3 sound like a chain saw! Get a deep powerful sound with the high flow you need...

Problem: After you have fitted an aftermarket set of headers, or muffler-  exhaust flow is greatly improved, but annoying harmonics, a "raspy" buzz, exist in the exhaust note. Since nearly every rear exhaust systems is tuned for the sound of the factory headers, your M3 can be too loud, too buzzy sounding... or both!

Solution: Our direct-replacement unit made exclusively for VAC by Fabspeed utilizes premium USA sourced and manufactured mandrel-bent & polished T304 stainless steel, completely TIG welded with CNC jet cut flanges for ultra-premium quality while still offering a competitive price.
Each one of our systems allows your engine to flow better than any other section 1 we have tested while properly controlling engine volume and delivering a pleasing and sporty sounding exhaust note that allow any M3 muffler to sound better.
Our design utilizes dual straight-thru resonators to 'suppresses' most of the annoying rasp-sound harmonics while continuing to provide a truly free flowing exhaust with no hot spots or restrictions.

Each pipe is the ideal 2.25" inner diameter as well as its matching resonator. Unlike using AR20 mufflers, or small Vibrant resonators- this is the perfect size for your application, smaller or larger transitions will cause reversion in the exhaust and reduction in performance as found in some other Rasp Pipes. These are completely unbaffled and do not sap power for sound reduction as found in other styles.

Our Rasp Pipe also offers some truly high end options:
-Capability to swap on high-flow HJS 200 Cell Catalytic Converters at any time.
-Fabspeed Oxygen Sensor Angle-Simulators to aid with ECU tuning/ CEL if needed after installation of a header
-Smooth piping-to-resonator transitions
-Largest, highest flowing resonators possible that will fit the E46 chassis
