B58 RSS

The BMW B58 3.0-liter turbocharged inline-6 is widely regarded as one of the best engines BMW has ever produced. Found in the 240i, 440i, 540i, 640i GT, and X4 M40i, the B58 combines smooth power delivery with remarkable tuning potential. The single most effective bolt-on modification for this platform is replacing the restrictive factory downpipe with a catless unit.This guide covers catless downpipe options across the entire B58 lineup, real-world power gains, exhaust sound changes, fitment, and why an ECU calibration is essential.The B58 3.0T — Platform OverviewThe B58 is BMW's 3.0-liter turbocharged inline-6, the spiritual successor to the legendary...

The Toyota GR Supra A90 has become one of the most popular drag racing platforms in the world. With the BMW-sourced B58 3.0-litre inline-six responding aggressively to bolt-ons and ECU calibration, Supras are routinely running deep into the 9-second zone on the quarter mile. At those power levels, factory wheels are a liability. Beadlock drag wheels are the solution — and choosing the right set means understanding fitment, construction, and what actually matters on the strip. This guide covers everything you need to know about beadlock drag wheels for the GR Supra A90 and A91, from bolt pattern and offset...

Catless downpipes are one of the highest-impact bolt-on modifications for turbocharged BMW engines. By removing the restrictive factory catalytic converters, exhaust gas exits the turbocharger housing with significantly less backpressure — meaning the turbo spools faster, exhaust gas temperatures drop, and the ECU has more headroom to add power when paired with a Stage 2 tune. YPG Motorsport stocks catless, 200-cell and 400-cell high-flow catted downpipes for every major BMW performance engine — from the S55 inline-6 in the M3/M4 to the S63TU twin-turbo V8 in the M5 and M6, plus the B58 single-turbo six powering the 240i through 640i...
