Has the Imperial Blitz Exhaust for tomos a55 engines got discontinued. I've read reviews about them and saw videos so I know they exist but i cannot find it on any site I go to. The only place i found it was on a link from google, but if i go directly to their site i look for it i can't find. So is it still around if so where can i find? And if its not what are some good alternatives that will mount up to a tomos streetmate a55 without modding it in any way.
