Spector, yea, I agree with you. I'm sure where there's a will there's a way. My nephew is not prepared mechanically to do the work himself so he would need to buy all the necessary parts and then have a muffler shop weld things up for him. And like you said, pulling things apart later would not be easy. Given that he'd have to take everything to a shop to get done I think that it won't be much more expensive for him just to get the MAC setup since that can be bolted together he'll be able to do it himself.
