[zoom400ex]

I am looking to buy a new slip-on for my 400ex. i am tryingto decide between a t-4 and a hmf. i know that hmf is new but i hear that they are a good slip on to get. i was wondering if anyone could tell me which one was better. and i wan't to know if they are really really loud!!. i have to ride through neighborhoods so i can't get the cops called every 5 mins.!!! i would appreciate anyones advice. thanks

From personal experiance, the t-4 is very VERY loud. I have heard the hmf is too. I would look to a big gun quiet series, or a white brothers e series with a quiet core. FMF has a new quiet series powercore IV that is supposed to be pretty good too.
