Parts Needed

Exhaust header studs -- (Qty: 0 to 4) Note: Only required if yours are damaged, corroded, or you just want to replace them. Yamaha part#: 95617-08625-00, BOLT, STUD. Or you can get stainless steel ones (like I did) from places like MMS Stainless. I got ones with hex (allen) recesses in the ends for easy replacement. Important Note: If you replace your studs with standard ends (not ones with hex recesses in the ends), you will also need two metric nuts (8mm X 1.25) for installation -- available at hardware and home-improvement stores.

Exhaust header flanges -- (only necessary if you destroy your current flanges). You must determine the make/model of your exhaust system, and contact the manufacturer. It is beyond the scope of this article to list all past, current, and possible future manufacturer possibilities. Post questions in the forum section of this website if you need help identifying your exhaust make/model. Note: Flanges are fairly standardized, so a flange from one manufacturer may well fit an exhaust pipe from another manufacturer.

Exhaust gaskets -- (Qty: 2, unless your flanges are thin compared to stock, in which case you might need 4). You can use any of the following:

• Yamaha O.E.M. part#: 3EG-14613-00-00, GASKET, EXHAUST PIPE. (about $6 ea.)
• From your local auto parts store: Fel-Pro 23588, These fit fine on all models, without triming. (about $1 ea.)
• From your local auto parts store: Fel-Pro 23561. These must be trimmed a little, but are easier to find. (about $1 ea.)
