Handmade TIG-welded stainless steel system with two 70 mm pipes and absorption silencers. For S55 B30 A with 317/331 kW, including Competition.
Without OPF it fits from the catalytic converter; the OPF version fits from the existing particulate filter. ECE approval requires the matching Bull-X Tronic ECE controller and the applicable vehicle approval.
A tailpipe selection supplies two sets for four tailpipes in total. Prices include the required quantities. Tailpipes remain optional on the OPF version, matching the manufacturer.
