I have decided to make the leap and have a custom exhaust fabbed up for the R. Gonna be 3" from the DP back, and using a Magnaflow Muffler.....I have 2 questions.<p>1. Sould I put in a resonator?? I DO NOT want it to be ORIGINAL Evolve or Svenske loud....I want it to have a nice cruising tone, and sound like a monster at WOT....and a small amount of interior resonance is ok.<p>2. From what I see, the Magnaflow P/N: 14219 is what most are using in their Svenkse system to take it down a notch....is this the correct P/N?? I just want to get these things right before I place the order.
