does anyone have any info on this exhaust? or any links to more about this exhaust? Its a 5zigen as u can see in the pic, but how good are the 5zigen exhausts? How much power you gain 10-15? its a cat back exhaust, and im guessing its a straight pipe, i havent seen this kind of exhaust before, i seen the apexi type ones that were made by 5zigen, but never thought they make these types.
if anyone has any info on this , let me know. thanks.
