Big mouth stainless performance exhaust for the 125 and 150cc GY6 4-stroke engines.
When changing a cylinder kit or an exhaust, it’s a good idea to pick up a few extra
8mm Studs
since these can easily need replacing and bring your project to a grinding halt while you wait.
These nuts
are essential. The smaller, 10mm diameter head allows for extra clearance between your wrench and the head for easy access. Standard 8mm thread diameter.
