E9 CS Coupe – Stainless Exhaust System (M30B35 Swap HOTROD)




This is our most aggressive exhaust system for the 3.0CS Coupes. We use this system on our M30 stroker engines with great success. Included is our high-flow tubular header.

TIG-welded right here in Southern California using US-sourced stainless steel. Headers and downpipe are ceramic coated to keep under-hood temperatures in check.
