BOS Muffler Oval from ´07

The brand new XJR has serially a 4-1 exhaust system first with slip-on muffler. The oval BOS mufflers are available with polished aluminium, polished stainless stell or carbon sleeve. All mufflers have an E-approval mark and are available with or without catalyser. Allowed for street legal use are only mufflers with catalyser (extra charge 60.-€). The DB-killer which is inserted in the back of the muffler can be take out easily at racetracks. Even legally the BOS muffler has a lot to offer, the street legal version perfroms a plus of more than 10bhp and 13Nm more torque direct noticing during driving.

If the BOS mufflers seam to be too quiet, you can also get a non street legal DB-maker which is inserted from the front into the muffler and is not to bee seen from outside.
