I’m pretty happy with the S-Type but it’s pretty tame. Seat of the pants feels a little peppier. Post up a video if you get the ATAK installed.Thanks for uploading this - just as I suspected it is really not that loud. I think I am going to get the ATAK. I want a bit of oomph rumph to the rumble LOL. I just was worried that the ATAK might sound like a bro-dozer but I don't believe it will.
