The modular cat-back is finalized and officially in production. Sound clips will be coming soon.

Designed to deliver improved performance and a more refined sound over conventional exhaust setups, the system also helps reduce exhaust turbulence and backpressure, allowing the turbo to operate more efficiently and build boost more effectively.

🔥 PRE-ORDER NOW: IRL Modular Midpipe for X3M / X4M 🔥

Unlock the next level of performance for your BMW X3M and X4M with the IRL Modular Midpipe engineered for drivers who demand real gains, refined tone, and track-ready flow.

This isn’t just an exhaust upgrade it’s a full transformation of how your S58 breathes.

⚡ Built for Maximum Performance
Designed to dramatically improve exhaust flow, the IRL modular midpipe helps reduce restriction in the factory system, supporting better turbo efficiency and improved response under load. The result is a freer revving engine with enhanced top-end pull and sharper throttle feel.

📉 Optimized Flow & Turbo Efficiency
By reducing backpressure and improving exhaust evacuation, this system can contribute to improved operating efficiency under boost, helping the turbos work more freely in high-load conditions.

🔧 Fully Modular V-Band Design
Precision V-band connections allow for easy install, perfect alignment, and future flexibility. Swap configurations without replacing the entire system — built for enthusiasts who evolve their setup over time.

🎶 Refined Aggressive Tone
Expect a deeper, more aggressive exhaust note with reduced harshness and improved character throughout the rev range. Cold starts hit harder, while WOT delivers a clean, exotic-style turbo howl unique to the S58 platform.

🏁 Track-Ready, Daily-Friendly
Lightweight construction, clean fitment, and modular adaptability make this the ideal upgrade whether you’re daily driving or pushing hard at the track.

We took the shop G90 to one of the most famous roads in the world, the Tail of the Dragon 318 curves in just 11 miles.

We were genuinely impressed by how well this car performed. For a full size luxury sedan, the way it shifts its weight through the corners is incredibly balanced and composed. The sound is equally impressive, making the driving experience even more engaging.

This G90 is equipped with:

Exhaust
titanium intakes
height-adjustable suspension
three-piece wheels
Pilot Sport 5S tires
full carbon

The result is a car that looks refined, sounds aggressive, and handles far better than you would ever expect from a vehicle of this size.

Took the land yacht to Tail of the Dragon, and for a car of this size, it performed exceptionally well. The way it transfers weight through the corners is pure perfection.

Development opportunities are here for the F80 M3 & F82 M4.

We’re currently seeking local Chicagoland-area vehicles for development and testing.

If you’re interested in being part of the next stage of performance refinement, reach out for details.

Unleash the beast. IRL.

The first of the F97 F98 Modular is heading on over to for some real world testing.

Simplified and sounding good with the v2 Midpipe.

What’s cooking good looking???
