I am running stock head pipe, CFRs, Cobra PowrFlo Intake, and the Power Vision. No problems whatsoever. No bluing.

 

I emailed and called www.cfrmotorcycle.com have not heard back from them. Is that normal for the company or should I buy through someone else or even another brand ?

 

Customer service was great every time I called. I found there were times of the day that were best to call because someone always answered...their wise I would get a message. Usually 4:30ish EST if I recall correctly.

If I'm not mistaken, they can be found cheaper on the web with shipping included.

 

I switched from Bassani 3.5 mufflers to CFRs and ran an auto tune that made very little changes. I don't known what power loss people talk about - my butt dyno says otherwise.

 

I've been running them for 3 years coupled with V&H power dual headers, heavy breather and SERT tuner. No issues.
