I have a 06 flhx/i streetglide and have installed bub dresser dog slip ons,s/e air cleaner and a techlusion TFI and it runs great.
My question is by removing the stock mufflers im I hurting anything? I had it dyno tuned at the dealer and they never said a word about it and I did'nt even know it had catalyst mufflers. thanx for your input.

 

Nawp not hurting a thing. It's just EPA BULLSH*T[:@]

 

Thanx! Thats what I thought but the motor company wants to freak you out.
