Hey is anyone running a hot seat tunable pipe? I have one on my 400 scrambler and i'm running it without any of the shims in it. Will i see much of an increase in low end power if i install the shims? I don't want to do it if it's not going to be worth it. Thanks for any info

 

The shims will add a little low-end but they cut the top-end bad. I found no way to have any good low-end with that pipe. It was great for mid-range and top-end but don't expect to ever have a decent low-end with it.

 

You'd do well to contact rick at ritter Cycle Racing. He has a VERY down to earth perspective on things! His # is 618-644-3211
