Just wondering if anyone is running the Brock short streetsmart system 3rd gen on their 08 busa and how it did performance and sound wise ( if anyone has a soundclip that would be great) also how much difference there is performance and sound wise compared to the alien head and the Yosh r-77 full systems. I have narrowed it down to one of these 3 I like the performance of the alien head but the looks of the longer mufflers of the other 2. Thanks, gap4652
