Hey! I'm thinking about adding the Magnaflow Riot (2 into 1, in black) exhaust to my '09 Street Bob. I installed a K&N air filter not long after I bought the bike. I installed the Doebeck Gen 4 about 3 years ago. My review of the Gen 4 is in post 51006. I'm looking forward to tweaking the Gen 4 for the new exhaust. I would appreciate comments on the Magnaflow Riot but my main question is: Does Magnaflow offer a discount code for HDTALKING members? I searched, but everyone can be stupid at times. Maybe this is one of my times. I will gladly provide feedback for my combination of add-ons. Oh, I forgot. Be Cool.
