Stainless steel exhaust systems for the 1275cc are manufactured by Double S Exhausts from 309 and 401 grade stainless steel, carrying a lifetime guarantee against corrosion. The systems are available in both standard and sports specifications, with options including single-box, twin-box, and twin-box with twin tail pipes.
1275cc Identification
The correct 1275cc stainless system depends on two factors: the manifold type (bell or flanged) and the system layout (single-box for pre-1970, crossbox for 1970 to 1974). A car with the bell-type manifold and a single-box layout requires the Type 1 equivalent system, while a car with the flanged manifold and crossbox layout requires the Type 3 equivalent. The system specification must be confirmed before ordering.
Standard vs Performance Exhaust Note
Standard systems replicate the OE exhaust note, the subdued, purposeful character that is part of the Midget’s identity. Sports systems use larger-bore pipework and less restrictive silencer internals for improved gas flow, producing a sportier and more prominent exhaust note with a measurable improvement in power at higher rpm. Both specifications are manufactured to the same accurate tolerances for straightforward fitment, with mirror-polished silencers that maintain their appearance indefinitely.
