I got the foam piece out of the firewall but the one in the disc I can't get to I can't get the hose off is there an easy way to do this or is there another foam peace I can remove. Ps yes I like it loud thanks guys

 

Just grab the hose and pull it off the back side of the diaphragm.

 

Ok I've tried that unless I wasn't pulling hard enough I thought I as going to break it

 

I had the same issue. After struggling for a minute or two I decided to try it with only one foam removed... Was happy with just the firewall foam removed. I think taking both out may produce too much of a harsh sound... Now I just need the GT500 axlebacks!...

 

i agree, sounds about perfect with one peice out. both it might sound a little crazy. try it with one out first and see what you think

 

Got its guys I love both of them out I had one out for over a month lol too quiet.
