I took the plunge and modified the factory pipes on my bike by removing the baffles. It sounds great but had a little popping with shifting. So I was advised to have Lloyds install their fuel controller, high performance air filter and IAV and disconnect the 02 sensors. I went to Myrtle Beach when they were there and had this completed and ran across the dyno. All was good but on my trip back to NC the popping was still there. I sent Lloyds an email and have yet to hear from them. So much for their great work and customer service. Any suggestions for the problem? Maybe install baffled pipes? If so, what suggestions do any of you have. I don't want loud pipes but a good deep sound.
