The MadDad(TM) Metal V2 downpipe is one of the most well received hi-flow metal substrate downpipes in the Subaru performance community. In this recent update, we've add an auxilury 02 sensor optimized for wideband/percision tuning. The MadDad Metal V2 downpipe is the only downpipe on the market that was explicitly designed to minimize or eliminate boost creep that many Subaru owners experience, in particular with STi models. The unique arrangement of a metal substrate cat closer to the turbo, but combined with a catless wastegate ensures fast boost control response.
The MadDad(TM) Metal V2 downpipe is the only downpipe with a 14 DAY MONEY BACK GAURANTEE....EVEN AFTER YOU INSTALL IT. See if any other performance brand will dare to match it
Excellent Pipe
