This set of upper and lower clamps is the perfect addition to our Hanger Kit, especially if you're going back to a stock muffler from aftermarket and no longer have these required clamps. The stock mufflers (standard E36 or M3) use this clamp method around a lip on the muffler body. But most aftermarket muffler systems don't use the clamp and bolt straight to the rubber hanger. So these stock pieces are often thrown away which will make it impossible to re-install the stock muffler. These are the OEM muffler clamps.

Kit Includes:

18211723555 (18201402479), upper clamp bracket (L shaped)

18211723410, lower clamp bracket

M8 hex bolt

M8 hex nut x 2
Sold as pictured - order 2 for a complete muffler.

This item fits the following BMWs:
1992-1999 E36 BMW 323is 323ic 325i 325is 325ic 328i 328is 328ic M3

Looking to replace your valve stem seals due to leaks, cracks, splits, or even during an upgrade of your camshafts, valve springs, or valves? Supertech valve stem seals are the way to go! This cheap but effective seal replaces the stock BMW seals that are notoriously prone to issues due to heat cycles and chemicals which cause the seals to become weak and brittle. Supertech seals offer a significantly longer life span and are resistant to both heat and chemicals thanks to their use of Viton or Polyacrylic construction (dependant on valve type). That means less time in the garage and more time on the street or track! These seals are also great for anyone who is looking to upgrade to dual valve springs thanks to the seal's overall thinner outer diameter! Guide OD: 9.8mm/.385" Seal OD: 13.2mm/.520"
