did you ever punch out the cat?

 

Hello,
Can anybody give me some feedback on the Thunderheader slip-on available for the switchback?
I would think it isn't as loud as a full system TH due to the cat in he existing head pipe.
I would love to hear how it sounds but unfortunately there is nothing on YouTube.

update on thunder header---put a few hundred miles on the slipon. not nearly as loud as expected. has a good deep sound. I have not decatted headpipe yet but that's next.my son put thunderheader slipons on his 2014 street glide and it is louder than mine . he has decat head pipes. its not too loud as you can still hear his radio good. to sum it up ; I really like the sound cant beat it for the price from direct cycle

 

Thanks for responding back 1968aj........I appreciate it...

 

I used a soft ail thunderheader and fabled a custom rear mount.

 

You have any photos on how you did that , I want do the same.

 

On a Switchback with floorboards? I thought the only difference between the Thunderheader for the softail and dyna was the rear mounting bracket for the pipe....cause they really look the same bend wise, and it’s that front pipe bend that gets in the way of the floorboards...ask me how I know....
