What a weekend, spent Saturday afternoon changing out the 09 SERG CC headers for a set from this site of 09 96 Cu.In, non Cat headers, the 2" Fullsac Baffles and the new mapping that Steve included. Everything is going smoothly until it comes to the grinding the welds. I had a pneumatic hand grinder and grinding away, broke the weld loose and could spin the baffles, even took the time to knock them down into the pipe as a tip on the instructions. well the weld was not smooth on the muffler and that d&*$ baffle would not come out. I was so concerned with not cutting a hole in the muffler I worked on that until I was so frustrated I had to leave it for the night and sleep on it. Woke up and had to play golf to clear my head from this project, and my golf game sucked cause I was still thinking about the pipes......Geeeez couldn't win for losing. well got home from golf and went back to work on the weld, ground it down in the muffler and the freakin baffle slid right out......wow imagine that. So if your going to do this project yourself, take the time to push the baffle into the pipe then knock the rest of the weld off the muffler and you'll have instant gratification.......So the bike sounds great the wife is ticked cause now my mod is louder then her Vance and Hines true dual with Bub mufflers with a Power Commander and Dyno........on her 07 SG....
