    Jim, now that you have used the dynaflow 40's for a while (guessing) how do you like them?

    What diameter on the pipes? Good sound on the system though.

    Well they were a bit loud. Just got the 57 on the road a wanted to hear any problems that might come up and the popping on backing off was too much.
    I had a pair or 18 in. glasspacks installed before the 40's and now all is good.
    The pipes are 2.5 inch.
