hey guys was just wondering what u guys thought about modifying stock endcap im planning to just take everything out of the stock endcap cutting the hole front out just leaving the flanges that go around the pipe and a bit for the screws for the disks... get some 5 inch disks and an endcap for the disks and making it that way if you no what i mean the disks will go on the end of the pipe with 6 screws holding them to the stock endcap

 

Check out my pics.

 

Dont forget any changes to exhaust flow will result in you needing to re-jet
