With the catted downpipe and Mishimoto tune, Mishimoto'saw dyno proven gains of up to 57 whp and 52 wtq using 93 octane fuel (see additional images for dyno chart). Above all, this downpipe provides a significant torque improvement in the low end and across the entire power band. The Mishimoto Performance Downpipe provided an extremely aggressive turbo and exhaust tone under acceleration and boost, giving you that aggressive tone you have been looking for!
