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.
Dual Sound Modes: Raw, high-revving S54 tone (open) or stock-like refinement (closed).
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.
Material: Brushed T304 stainless steel or Grade 5 titanium.
Weight Savings: ~8 lb lighter (Stainless) / ~18 lb lighter (Titanium) than OEM.

Finish: Brushed stainless or raw/brushed titanium.

Instructions are included for most parts that require any sort of knowledge to install.
Here's what to do if your parts come WITHOUT instructions:
1. Some parts are genuinely common sense on how they get installed
2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video
3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer
4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed
ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.
Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way
If the part was NOT installed, we accept returns within 14 days of delivery.
If the part WAS installed (or attempted installation), we cannot accept a return.
All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.
YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.
