I'm looking at mufflers for my new King. For this year I just want the slip ons then next year do a complete stage-1.
I like the look and sound of the CFR the best. But I have been told by some good turners that the CFR are hard to get power from. But some others say they don't have any trouble with the CFR.
I can find dyno sheets on just about all other mufflers but I cant find any with CFR. Has any one out there have a dyno sheet you could put up with CFR mufflers? I'm most interested in seeing them on stock motors. Thanks.

 

Maybe with less back pressure it is harder to get low end power? If you have your cats in then I wouldn't think it would be a problem. Without cats then it's probably pretty free flowing.

 

bump for sunday

 

Bummer, no info.

 

You WILL notice a drop in low end with just the CFR's.

I ran my 13 RG with just the mufflers for only about 2 months before going full stage one. Big difference. I'm not a tuner, but I know they're harder to tune than most. I went with a PCV and tune from fuel moto and it ran great...

Going a different route on the '14 SGS, am over the CFR'S. Sorry I can help with the dyno sheet. Its pretty common to buy the CFR's based solely on sound.

 

OP here, I wound up ordering Rush Big Louies after lots of research and phone calls. They should be here Tomorrow and if the weather is good I can try them out Sunday.

 

Nice!

I have the same pipes on the way. They seem to be gaining a lot of popularity lately.

 

I think the fact that no Dyno numbers are out there for the CFR exhaust says it all

 

What baffle did you order with the big Louies? I ordered mine with the 3" because that's what was recommended to me by rush when I called them. They are going on my stock 2015SGS

 

The 3" baffle will be fine unless you loose the cat then you will be in trouble. To big of a baffle with no back pressure but as long as you keep the cat you should be fine.
