Upgrade your BMW G90 M5 Catback Exhaust System with the LAB Valved Catback Exhaust, engineered specifically for the 2025+ BMW M5. Designed for the twin-turbo S68 engine, this performance exhaust system delivers a deeper, more aggressive tone while maintaining refined sound control through an advanced valve system.
This BMW G90 M5 catback exhaust system has been installed and test-fitted by our team to ensure perfect alignment, factory-level fitment, and true bolt-on installation. No cutting or welding required — just a seamless upgrade that transforms the sound and presence of your G90 M5.
Performance Exhaust Upgrade for the G90 M5
The LAB valved catback exhaust system for the BMW G90 M5 replaces the restrictive factory exhaust with a free-flowing 3.5-inch system designed for improved exhaust flow, sharper throttle response, and a more aggressive exhaust note.
This exhaust system gives the BMW G90 M5 S68 engine the deeper, commanding tone enthusiasts expect from a modern M car while maintaining comfort during normal driving.
Key Features

Designed specifically for BMW G90 M5 (2025+)

Premium Valve Control
The G90 M5 valved catback exhaust system allows drivers to control sound levels using factory M drive settings or the included valve controller.
Quiet when cruising and aggressive when desired, this system gives you full control over the exhaust sound of your BMW G90 M5 performance exhaust.
Note: The factory ECU does not always fully open the valves under low RPM or when the vehicle is in Park. The included valve controller allows full valve actuation for maximum sound on demand.
Built for the Next Generation BMW M5
The LAB BMW G90 M5 catback exhaust system with valves transforms the character of the vehicle. Cold starts become more dramatic, downshifts deliver sharper pops, and acceleration produces the deep performance tone the G90 M5 deserves.
For enthusiasts looking to upgrade the sound and performance of the 2025+ BMW G90 M5, this valved catback exhaust system delivers the perfect balance of aggression and refinement.

FAQs
Do you offer financing or payment plans?
Yes. At checkout, you can use Shop Pay Installments or Affirm to split your purchase into easy monthly payments. Financing options, including potential 0% interest plans, are shown during checkout and are subject to approval.
Will this part fit my BMW?
Yes. Every product we sell is verified for specific BMW models and chassis. If you want extra peace of mind, you can send us your model, year, or VIN and our team will personally confirm fitment before you order. BMW fitment accuracy is a priority at Legendary Auto Builders.
Are your parts OEM-quality or aftermarket replicas?
We only carry high-quality aftermarket parts that meet or exceed OEM standards. Each product page clearly outlines materials, construction, and finish so you know exactly what you’re getting. We do not sell low-grade replicas or poorly made components.
Where do you ship from and how long does shipping take?
Most in-stock orders ship from our California warehouse within 1–2 business days. Standard U.S. delivery typically takes 3–7 business days depending on location. Made-to-order or specialty items may require additional production time, which is always noted on the product page.
Can I install this myself, or do I need a professional?
Many of our products are designed for direct bolt-on installation and can be installed at home with basic tools. For more complex parts—such as aero components or performance upgrades—we recommend professional installation for best results. If you have questions about install difficulty, just reach out.
What happens if the part doesn’t fit my vehicle?
If there’s a fitment issue due to an error on our end, we’ll make it right. Our team will help resolve the issue quickly, whether that means an exchange or another solution. Fitment accuracy matters to us, and we stand behind the products we sell.
Are your products tested for quality and durability?
Yes. All products go through quality checks and are sourced from trusted manufacturers. We work closely with suppliers and installers to ensure every part meets our performance and durability standards before it ever reaches your car.
Do your products come with a warranty?
Most items include a warranty covering manufacturing defects. Warranty length and coverage details vary by product and are listed on the product page. If you ever have a concern, our support team is here to help.
