    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.

    Bigger is better and 2 into 1 flows best JMO
    Keep in mind that TOO hot is not good
    Exhaust gases flow because of low pressure and heat too muck backs up the exhaust and you do not get complete cylinder fill Sooooo the more overlap in your valves the best exhaust is a must
    Length, diameter and internal baffling is crucial JMO Read all about it in The Big Twin High Performance Guide
    [​IMG] I have had this forever a VERY good read, but not cheap any more, It centers on Evos and Shovels, tho it applies to ALL HD engines in theory
    Wish I had written it, I have a few new ideas I will run past dolt,
