Reviews:

Strup's muffler system also comes to us with a 13 in polished T-304 stainless steel muffler and is capped with a polished 4 in stainless steel tip. The hangars were also well placed, giving maximum ground clearance for the muffler while still fitting the bumper cutout well.

On the dyno, the V2.0 system peaked out at 97.57 WHP; torque checked in at 100.42 lb/ft TQ at the highest level. Statistically speaking, the gains and losses seen in the crossover graphs are negligible.
