SLP pipes and cans are pretty much made to run with each other, so you could possibly lose some performance from the pipe if you open up your exhaust outlet with a different can. Seems silly to spend that much money on the system that only gains you a little horsepower and not run it in the manner that it was intended. If you wanna mix & match power & sound, it seems like the Aaen pipe, fuel controller and can of your choice would be the way to go. Unless you already have the SLP kit, that is. There's also a thread that just started on the Aaen pipe, if you wanna keep an eye on that. They guy is gonna test it out in a week or so I think
