LAB Design Catback Exhaust System – Lamborghini Temerario
Pure V8 Sound - USA MADE - No Downpipes Required.
The LAB Design Catback Exhaust System for the Lamborghini Temerario was developed to unlock a more aggressive, raw, and exotic exhaust note while keeping the factory catalytic converters in place.
At the center of the system is our extended 5-inch X-section, where the left and right exhaust banks merge together before exiting through the tips. Compared to a traditional short crossover, LAB uses a much longer merge section to allow the exhaust pulses from both banks to interact for a greater distance — helping create a smoother, more blended, higher-pitched exhaust character.
The system is completely muffler-free, eliminating the restrictive factory rear muffling section and allowing the Temerario's V8 to be heard the way it should be.
Best of all, the LAB Catback is designed to bolt directly to the factory catalytic converters, meaning aftermarket downpipes are not required to install or enjoy the system.

THE LAB X-SECTION
The defining feature of this system is the oversized, extended crossover before the exhaust tips.
Rather than keeping the two banks separated until the very end, the LAB system brings both sides together through a long 5-inch merge section. This allows the pulses from each bank to blend before exiting, creating a more unified exhaust note and helping move the sound away from the traditional separated-bank V8 tone.

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.
