Stainless Steel Exhaust Deflector Smooth. How about this highly polished stainless steel exhaust deflector for your favorite ride? Put it on your Cruiser, Hot Rod, or more. It is about 8 1/2" long and 5 3/4" wide at the outer end. You can use a couple of 1/4" bolts or just wrap it around the tail pipe and use a hose clamp. This is the perfect way to keep the exhaust system from spitting all over the garage door.
