Unleash the full potential of your 2023+ BMW 735i or 740i with the GCA Performance B58 Downpipe, engineered specifically for the G70 7-Series equipped with BMW's legendary 3.0L turbocharged B58 inline-six engine.
Replacing the restrictive factory downpipe dramatically improves exhaust flow, allowing the turbocharger to spool faster while reducing back pressure. The result is improved throttle response, stronger acceleration, increased horsepower and torque potential, and a deeper, more aggressive exhaust note that perfectly complements the smooth characteristics of the B58 engine.
Constructed from premium T304 stainless steel, this performance downpipe is built to withstand extreme exhaust temperatures while providing outstanding corrosion resistance and long-lasting durability. Precision TIG welds ensure exceptional strength and OEM-quality fitment for a straightforward bolt-on installation.
For enthusiasts seeking maximum performance, pairing this downpipe with a proper ECU tune unlocks even greater horsepower and torque gains while maintaining compatibility with your factory exhaust layout.
Designed under our GCA Performance line, this upgrade delivers the ideal balance of performance, sound, reliability, and premium fitment.
We stand behind our products with a 1-Year Warranty.
