Where to get pipes for muffler delete
 

So I've been thinking about dropping the muffler and trying out something like the AAM deletes. Does anyone know of anywhere to simply buy pipes like this that bolt to where the muffler bolts on? I've got tips I want to use and I just want to weld them to these pipes to try it out without having to buy a name brand for that much $$. Something like this that was recently sold on here...

go to an exhaust shop and have them do it. another member on here got them done for about $150.
