This pipe was designed in house using CAD Engineering, Flow Bench testing and Dyno Proven. Over one year went into designing this pipe, with multiple designs and performance changes, to come up with the ultimate shortie header. This .028 wall header will out flow and out perform any other short header on the market, period.
Header does not come with silencer.
The header does have its own bracing, however we do recommend additional bracing to support the silencer.
