If your TORs are anything like mine, the stock pipes will be easier to de-baffle. I have the short Speedmaster off-roads, which aren't much louder than stock. And after taking them off and looking at them, I don't know how to go about making them louder...which is why I ended up with Epcos. Looking through my pipes, there's a straight hole about 1/2-3/4" inches in diameter running through it's entire. length, so there aren't any baffles to drill out.
