Maybe it's your MAP. I just put on V&H CS1 on mine with no fuel adjustments and nothing close to loss of all low end torque. I wouldn't think the Two Bro's would affect your bottom end that much.
'Two Bro's would affect your bottom end'.....hmmmm.....we'll have none of that on my watch, thank you very much!
Wow, always going for the gutter
So I put on a Two Brothers slip on with a new map in the power commander to match and I love the sound but the loss of low end torque is sad. I wonder if I pony up for the full Area's P Exhaust if I will have the same problem?
I had the same problem and it is a normal symptom but your mid-range and upper HP should increase. If you haven't pulled the flies yet, that will make a big difference in the low end torque.If you're still not happy, go with the Area-p full system. It rocks from the bottom up!
