Decided to change my exhaust now for the 4th and final time!!

My exhaust started off as a top speed CBE with no resonators true dual system.



It was pretty loud, very deep, and put a smily on my face every time I drove! It was however ever so slightly raspy when it was cold so I decided to add 18" resonators to it in the two straight mid pipes. With the resonators it got very quite, a little deeper, and ZERO RASP!!

I knew at some point though I was going with test pipes or LTH's! Once I got LTH the car was louder than ever before! But OMG the rasp!!!! It sounded horrible. So I decided to install some Helmholtz resonators that motordyne uses. Helmholtz's can actually add HP because of their design over inline resonators with scavenging. I installed them right were the x pipe bolts to the header. Once again I lost all my volume but I only lost about 90% of the rasp.

The last modification I was planning on removing the muffler and the 18" resonators and straight piping it with 2 more Helmholtz welded at the back where motordyne has his installed because they seemed to work so well before. First though I wanted to see how it sounded with taking baby steps. So I cut off the muffler and straight piped it from the 18" resonators back using the top speed exhaust tips. We'll this was all I needed and I don't want to mess it up by going further! The volume is louder than ever before!!!! Omg its loud! But there is zero rasp now, zero drone, just deep heavy kinda V8 sounding/drag bike motorcycle sound. I wish it was a little more exotic but again I don't want to loose this volume and zero rasp/drone. Videos won't do it justice, wish everyone could take a ride haha.
