Bring the maximum
power out of your exhaust with the aFe Power Muffler-Delete Pipe. This
pipe is constructed out of 409 stainless steel and is used to eliminate
the 4" In/Out muffler used in most factory or performance 4" exhaust
systems. You will love the aggressive exhaust note of a 4" system with
no muffler while maximizing exhaust flow, throttle response and
performance. This pipe fits most 4" exhaust systems.
