I'm replacing the baffles in my V&H Big Shot longs with the quiet baffles from Big City Thunder. I had to remove the heat shields to access the mounting hole which is a couple of inches from the end of the pipes. The new baffles are currently installed 3" from the end of the pipes and sound great. The autotune of the installed Thundermax ECM will correct any change required for the EFI map.
The instructions that come with the baffles indicate that they should be installed at least 3" in from the end though 6" is the 'sweet spot'. The instructions also indicate that they can be installed in front of the original baffles that have been cut off which would put them about 11" in from the end of the pipes that would make them quieter still.
I'd like to optimize the performance with these new baffles. Do I
1. Leave them alone, 3" from the end of the pipes
2. Drill new holes 6" from the end of the pipes and re-install new baffles
3. Install in front of original baffles (cut off) about 11" in end.
Thanks
