i seen in some magazines a new turn down chrome cap you replace the standard white bros cap with at the end.....it makes it look like the big gun, yoshimura type racing pipes...does anyone know anything about these, like does it produce any more power, make it sound better or anything? just wondering before i ordered one....thanks!

 

It's like the standard one. If you run the disks, then the cap is just for looks. It won't change performance in any way whatsoever.
