looking for a little help here thinking of buying thundercones slip onsfor my 07 roadking how
will it run performance wise with stock headers on it,,dose anyone haveany better ideas?

 

What is your goal with the exhaust change?

 

better performance and sound

 

It should have good bottom end with the stock headers and appropriate tuning,the true duals do sound better but you lose bottom end on a stock motor.

 

Should run the klockwerks double back head pipes and bub mufflers. Drove a bagger in strugis with a 95" kit on it and that set up. Runs perfect, had tons of low end torque. Bike is on cover of December issue easyriders
