2007 stock exhaust

i'm trying to save some money by having my stock exhausts modified. Has anybody ever done this and what were the results? Instead of spending $500 on a Jardine RT 1 slip on, i thought about doing this. Any help would be greatly appreciated.....thanks again...

You can drill holles in the back of the can. Sounds louder but not as deep and nice as aftermarket pipe. Good for the time you need to save money for a pipe. Unhook the servo cables for better sound too.
