EVO RACING SERIES EXHAUST - MX vs ECO SYSTEM EXHAUST - MX

Just like the tittle says........Does anyone have any info on the pros and cons of the two Big Gun pipes for a 2010 YZ450F. i am on the fence between the two. so i am looking at the Big Gun EVO and the ECO..........are they the best bag for the buck and which of the two would you prefer?

um....ok, i am guessing that there aren't many big gun fans out there. i think i will go with the cheaper of the two:bonk:
