I added an extention tip to the end of DG 6:1. Purchased from local auto store, chrome, took to muffler shop with bags and had them weld on. It looks a little funny with the main cone sweeping up and the tip horizontal, has a slight down turn bevel. It saved the bag though!
As far as the stage three, based on what I discovered with it an dyno runs, it is going to take a lot more than K&N's to lean it out.
I started with their 122's and ended up at 108 and that's with all the above!
Later,
