Tegiwa Catless Downpipes for the S63 engine as fitted to the F10 M5 and F12/F13 M6.

These stainless steel, TIG-welded downpipes are the perfect way to de-restrict the exhaust system of the S63 engine, allowing huge power potential and increased turbo spool. Over 670bhp is possible in conjunction with a Stage 2 tune. They also improve sound for a deeper, more purposeful exhaust note.

Please note that removal of emissions equipment is not MOT compliant and so these parts are for off-road use only.

Priced per pair. Remap required to avoid check engine light. Contact us for Bootmod3 tuning options.
