sounds like?
So would that be that they sound like pooh with a de-catted stock header or an aftermarket header...and if aftermarket, which one? and...btw, I have the cannons and will be installing a Cobra powerflow header this weekend and will update as to my thoughts of the new sound....

I've only tested with a decatted stock header. I suspect an aftermarket one will be much the same but do post your findings.

p51 is correct, my Street Cannons sounded awful with an aftermarket S&S Power Tune Duals header pipe. This aftermarket header did not have a cat. I now run 4" Rineharts and the sound is awesome!

I guess I'm in the minority, but I'd have to disagree... I changed to a de-catted stock header on my '14 Street Glide with Street Cannons. The sound was louder and definitely BETTER. To each his own, I guess.
Temps were also lower...

Attachment 416029Just got a OE head pipe that was removed before delivery,
Would it be easier to remove the cat from the hardly ran pipe or my pipe which has been heated up?
Plus I had a idea to extend one of the pipes in the collector to direct the exhaust a little more thru the left side, or should I just leave the collector open?
Thanks

Thanks all for the feedback on the CAT heat thing. I kinda know, come some warm day I am going to get out a drill and just drill the darn CAT out...
Do I really have to take the header off? I thought I read someone who didnt... ahh... guess its best to do so.
