Yes, jeff came out with a new graph and an updated import review site again. There was a dyno on the DC JDM 4-1 header with a 2.5 collector VS the SMSP adjustable header. There was a huge difference in WHP!!!!
This was on a mild 2 liter motor built by IB--
DC JMD 4-1 -->198whp
146 wtq
SMSP---------->208whp
152.8wtq
There was as much as a 20WHP difference between the two in the midrange,,,,,that is huge!!!!!!! All I have to say is that I would spend the extra cash for the SMSP an yday.
here is the link, enjoy
