Everest NEW HONDA GX340 11HP & GX390 13HP MUFFLER ASSEMBLY WITH HEAD SHIELD MANIFOLD & TWO GASKETS

First rate quality product at a very good price. Installation requires a longer set of 8 mm studs as the new muffler assembly has a larger exhaust header to head boss (good update for extra strength) that requires replacing the shorter stock studs. Use liberal amounts of WD40 three times a day for a few days to help with the removal of the old studs or they will break off flush at the head.

Nice muffler, it doesn't come with installation hardware. In my experience exhaust nuts and bolts are not reusable 90% of the time.

Awesome price compared to local store's and the product is the same, works great and was very convenient to order.

All parts bolted right up. Nice to have gaskets included. I give it only 3 stars, as It started to rust after the first use (1 hour and 15 minutes). I sprayed it with high heat rust oleum and seems to be ok- for now

As described and bonus that it came with the gaskets. Mounted and bolted like a breeze. I would recommend for any honda repair.

For my gx390 without any issues. Find your own bolts/nuts.

Everything I needed came with except the nuts for attatch manifold but the original nuts were all still there and were reusable

Is in good condition and it help out my father a lot
