The CRT Performance Equal Length Midpipe is a high-precision exhaust upgrade engineered for perfect flow balance, cleaner tone, and optimized turbo performance.
Unlike the traditional Single Midpipe, which produces a deep, raw growl, the Equal Length version delivers a smoother, more refined tone reminiscent of a motorsport-inspired inline-six.

By ensuring both turbochargers receive equal exhaust pulse timing, this design improves turbo spool consistency, throttle precision, and exhaust harmony — turning your X3M/X4M into a truly balanced performance machine.

Why Choose CRT Equal Length Midpipe

• Equalized exhaust flow – identical pipe length for balanced turbo pressure.

• Exotic straight-six tone – smooth, high-frequency sound without drone.

• Improved turbo response – faster spool and cleaner boost transition.

• Premium SS304 stainless steel – built to handle extreme heat and pressure.

• Perfect OEM fitment – direct Plug & Play replacement, no cutting or welding.

• Stage 2+ ready – designed for advanced tuning setups.
