The Valvetronic Designs Valved Section 3 brings modern exhaust control technology to the legendary BMW E46 M3. Designed to replace the heavy factory suitcase muffler, this upgrade delivers an unmatched S54 soundtrack with the ability to switch between aggressive and stock-like tones at will.

Direct Replacement: Connects to any section 2.

Material Options: Choose brushed T304 stainless steel for durability or Ti 6Al-4V Grade 5 titanium for ultimate weight savings.
Valves Open: Unleashes the iconic S54 scream with increased volume and sharper tone.
Valves Closed: Quiet, refined, and suitable for daily driving.
Rapid Valve Actuation: Instant open/close functionality for on-demand sound changes.

"Awesome setup! Easy install too !"
"I previously had a full Status Gruppe exhaust system on my M3 but it just didn't have the punch/sound I was looking for - enter in valvetronic designs - its exactly was I was looking for! I can keep the valves closed when I head off to work at 6am without worrying about bugging the neighbors and creating chaos so early in the morning. if you are looking to increase volume and unleash the true sound of your beast look no further than valvetronic designs! I can not say it enough!"
"Build quality is there the valve controller not the best mine stoped working after a couple of months and sound tone is alright"
"Valve closed sounds slightly louder than stock with similar rasp, valve open is F1 loud and glorious, beautiful welds and build quality, love it!!"
"I have been thinking of several brands of exhaust. But due to the budget, I chose Valvetronic Design and I did not regret buying it. Installation is straight forward, although the tips are a bit misalign compare to the OEM, almost touch the diffuser but the sound pitch is way better and louder than in their videos."
