hi, gramps t, i came across that site during my search. are they the manufacturer? they couldn't answer my questions. what do you or anyone else think about dyno power pipes. p.s. thanks for the quick reply.
I ran them on my FXDXT for 6-7K miles. There loud and small. They do not have the best slip-on sound . Good chrome, in fact they still look good setting on my bench. There cheep thats why I bought them, paid 70 bucks (with discount coupond) including free shipping. As for preformance : as good as the worst big name slip-ons if not better and that 's not bad.
