Had damage done to my '07 street bob on the freeway a couple weeks back. The other party's insurance is covering it and I took it to my local harley dealer for repairs. I had Supertrapp 2:1 supermegs that have to be replaced and the dealer inadvertantly ordered Kerker 2:1 supermegs and wants me to buy-off on them. I liked the performance of the Supertrapp pipes. Will I be disappointed (or stupid) if I accept the Kerker pipes?
