This Borla bottle/bullet-style resonator drops the sound level of a CrateMuffler by roughly 2-3 dB(A) and also works as a universal resonator in any matching system. The straight-through design lowers tone without degrading performance. 3in center inlet / 3in center outlet on a 4in round body (10in body, 15in overall). Un-notched necks for weld-in installation; T-304 stainless with CFF packing, a reversible design and no logo embossment.
