Also in the workshop
DPF and OPF cleaning and diagnosis.
Pi Motorsport is an exhaust specialist, not an exhaust-only business. For diesel or petrol vehicles with particulate-filter warnings, restricted performance or regeneration issues, we also offer assessment-led DPF and OPF cleaning.
View DPF and OPF cleaningLocal workshop. National specialist reach.
Birmingham remains the genuine workshop location and the core local search market. For complex fabrication, conversions, classics and premium builds, customers can prepare a project brief and travel from elsewhere in the UK.
Owners can use the detailed technical guides, regional travel information and clear assessment process to decide whether a specialist visit is worthwhile before arranging travel to the workshop.
