Db-killer made of galvanized steel with fins to lower the noise of the exhuast system: perfect as a spare part of the stock db-killer or in addition inside the muffler. The db-killer is ideal to reduce the exhaust noise and is very important to be with with aftermarket exhaust mufflers: a completely open exhaust means an excessive loss of torque. If even installin the db-killer the exhaust noise is too loud you can wrap around the inner part some layes of packing.
