    Sounds Great!

    Sounds and looks great! Got the 20" since a friend had the 14" and it was too loud in my ear while riding long distances but I liked the look of the alienhead. The 20" is somewhat quieter and set farther back so it doesn't get to me on long trips. Although it did take about 500 miles to break in. It was louder at first but now it's just right. I took about a 3 hour ride last weekend and I can't be happier. Brocks was great and they sent me 3 different maps to use with the system and shipping did not take long at all. Install was a breeze but I am a master mechanic. The black ceramic coating and black and gold nameplate match 2014 hayabusa very well. I have not yet put it on the dyno but my butt dyno says I've gained a good bit of power along with the sprint filter I also purchased. I am very pleased with my purchase and will be returning to buy more brocks products in the future.
