I have to slightly disagree with Sgt Jim (No Disrespect Sarg). My answer is Maybe. The majority of stock bikes that receive only exhaust up-grades do not require tuning but I have seen exceptions to this rule. I do have 2 points to make regarding your up-grade to Big Shots.
1. Stock Harley's, from the factory are mapped "Lean" and can benefit from proper mapping even if no up-grades are made.
2. Stage 1 intakes are inexpensive and will wake up the bike after proper tuning.
You'll receive very little or no performance gain from the Big Shots alone. For a few dollars more you can add a stage 1 intake and a inexpensive tuner. I recommend the Arlen Ness Big Sucker intake, and a V&H Fuel Pak. You'll then have the pipes you want, a full Stage 1, proper air fuel mixture, and a performance gain.
