Free Flow exhaust
Noticeable performance gains can be had by simply bolting on a free flow exhaust system. Your Morris will sound sporty, yet not obnoxious, and throaty, yet mellow. In other words, it will sound great, and the neighbors won't mind! A Maniflow LCB (Long center branch, part# EXH150) header is specially designed to fit the Morris engine compartment, and a matched, twin box, big bore muffler system (part# EXH116), also made by Maniflow, follows the same route as the original. Headers (EXH150) are optimally sized for small bore (948 & 1098 or stock 1275) or big bore (1275) engines (Order part# EXH150/B).
