SBM Powered F8x M3/M4 ESS Tuning Power Package
Created to be the ultimate performance upgrade for the F8x M3/M4 for use with the standard or M Performance exhaust system.
The OEM downpipes cause a major restriction in exhaust flow because of their integrated restrictive catalytic converters. This results in excessive back pressure and excessive heat, which ultimately affects overall performance at all RPM loads. ESS Tuning’s catless or high flow catted downpipes allow quicker turbo spooling and low back pressure proving significant hp/tq gains that can be felt immediately after installation.
When match to the ESS Tuning Stage 1+ ECU software and BMC air filters, power delivery is provided by optimising turbo boost pressure within the factory turbo efficiency range. This calibration allows for reliable, consistent performance and a very responsive and OEM like driving experience on pump fuel with a power output exceeding 390kw.
