Description

The exhaust note is the car's voice. Make it worth hearing. The Quad Note is a set of 304 stainless steel quad exhaust tips built for BMW E90, E92, and E93 models running a converted M3 or M4 bumper. It is the finishing sentence of a visual upgrade: the rear view that tells other drivers this car was built, not just bought.

Stainless 304 is not a decorative choice. It shrugs off UV, water, road salt, dirt, grease, and the mild acids that eat cheaper chrome finishes, which means the silver face keeps its optical line for years rather than seasons. The textured steel catches light differently from every angle, giving the rear a layered, engineered depth that a single round tip cannot produce. There is no paint on the surface, so there is nothing to chip, flake, or touch up after winter.

Fitment is precise: the set is designed for the E90 family with the M3/M4 bumper conversion, and the quad layout mirrors the factory performance stance without tipping into caricature. Professional installation is recommended, and the package includes everything you need for the rear section. If your car currently wears two tips on the left, this kit is the upgrade that completes the look.

This is not an exhaust tip. It is the period at the end of the build.

Application Scenarios

The Quad Note earns its place on the weekend build and the daily driver alike. Enthusiasts completing an M3 bumper conversion use it to close the gap between factory parts and aftermarket intent. Owners who want the performance look without committing to a full exhaust system use it as the visible signature of the build. It is equally at home on cars that see track days and cars that only see the office parking garage, because the stainless surface is chosen to survive both.

Frequently Asked Questions

Q: Will these fit my BMW without the M3 bumper?

A: The quad layout is designed for the M3/M4 bumper conversion. On a standard E90 rear bumper the spacing and cutouts will not align, so the conversion is required.

Q: Do I need to paint or coat them?

A: No. The 304 stainless finish is the final surface. It resists UV, water, salt, and mild acids without any coating, and it is easy to clean with regular car care products.

Q: Can I install these myself?

A: A capable DIYer with basic tools can install them, but professional installation is recommended so the tips sit level and the clamps are torqued correctly.

Q: Will they change the exhaust sound?

A: These are tips and trims, not muffler replacements, so the sound character of the exhaust remains essentially unchanged. The upgrade is visual.

Q: How do I clean stainless exhaust tips?

A: Wipe with a microfiber cloth and a stainless cleaner, or soap and water for light dirt. Avoid abrasive pads that could scratch the brushed texture.

Q: Does the kit include mounting clamps and hardware?

A: The package includes the stainless tips and the mounting hardware needed for the rear section. If your bumper has been modified beyond the standard M3/M4 conversion, contact our team to confirm fitment before ordering.

Q: How long do the tips stay looking new?

A: With regular washing, the stainless finish holds its silver tone for years. Road salt and brake dust are the main enemies, so a rinse during normal car washes keeps the face clean and bright.

Finished my build

Exactly what my build needed to finish the rear. The texture of the steel catches light beautifully and they have survived a salty winter so far.

Solid stainless steel

Solid stainless steel, great weight to them. Took a weekend to align the clamps just right but the result is worth it. No rust after a month.

Factory look on my E92

The quad tips look factory on my E92 with the M3 bumper. The stainless finish is excellent quality and the install took about an hour.
