Hello members. Newby here and have enjoyed the site since the purchase of 2008 Speedy. I recently purchased Arrow slip-ons (Titanium ovals with mid-pipe). The fit and finish are awesome, but the decel popping is dreadful even after the dealer did the arrow download for high mounts/no cat! What now? I have read about Tuneboy on this site but the technician at the dealer says to stay away from it. (?) Any help would be appreciated.
