The proper downpipe (track use only)

This Downpipe is designed to be ran on the G series (25-550, 25-660, 30-660, 30-770, Etc.). The purpose is to get rid of the stock downpipe adapter which is a massive restriction in the exhaust system causing turbulence and excessive back pressure. 

Without a re-tune, the test car picked up .98 seconds on the 70-120mph times, and a whopping 15whp and 31wtq, again WITHOUT a re-tune! 

If you are going for power and overall motor efficiency, this is an absolute must.
