This just happened yesterday, and I have contacted the dealer (will remain unnamed as long as I am taken care of, as he promised) where I bought the mufflers. I agree, at the price, this should have never happened, and as for my dyno, the AFR line is as flat as it could possibly be at with a straight downward line from 14 at 1750 RPM to 12 at 6300.
I have never had any quality i.e. V&H, and Rinehart, ever change color, even after two dyno tunes on both. Needless to say, I am pretty sick about this, and hope that the problem will be fixed as promised. Sometime you just have to have a little faith.

 

I have cfr's for about 2k miles and no problems... I have power duals and pc5 with map from eastern performance!!! Hope not to have to go thru this ****!!!! Like others have said its a lot of $$$$ for something like this to happen if it's not ur fault should b taken care of!!!

 

Running CFR's on both my CVO Ultra and SG. Have had it on the SG for almost 2 years with no issues and on the CVO for 5 months with no issues.

 

Buddy of mine just put them on his SG with no tune about a month ago. He loves em....no issues.

 

I didn't have an issue until the tune yesterday.

 

well unless cfr make good on yours we won't be using them!!! and we will also spread the word very fast for others to stay away also. DO THE RIGHT THING CFR!!!!!!!

 

Have had my CFRs on for about 1k miles. No problems at all. They are black though.
I love them!!!!!

 

hmmmm

You realize that your replying to a post from CFR that is from 2010? Website may have worked then.

This guys pipes didn't change color until he got it tuned, so I'd half to lean (pun intended) towards the tune causing his issues. I do hope he gets some new pipes for his troubles.
