Supercharge my motor

You really need to state what year vehicle you have, so we know what version V10 you are talking about. The early version V10s had a lot of breathing problems, which means there is a ton of gain available, just by improving breathing. If you are not running headers, I would strongly suggest that headers and straight through mufflers is the first place to start. 2 reasons, the first being that you may get the improvement you desire from a superchartger alone. Second reason, and here is the biggy, if you increase the air flow into the engine, but do not manage getting the air out of the engine, all you will do is generate more heat, rather than putting power to the ground. Yes, it would make a small difference, but you would be highly limited in your boost as a result of heat. So the answer is no, there is no practical way to install a supercharger without opening up the exhaust. Since you have to do that anyway, then why not start there.
I would recommend Thorley (218Y1C) for a couple of reasons. First, they use thicker gauge steel pipes than Banks (14ga), which means the engine compartment is quieter. Secondly performance wise, every test I have read when one compares Tr-Y designs, to conventional designs, the Tri-Y always have a much broader power band, as well as slightly greater power over all. Secondly, use Magnaflow mufflers. There are straight through design, perform better than baffled mufflers, and are typically quieter inside the vehicle. I went through a muffler battle with my coach, trying several different muffler types on the same exhaust. I did zero to 60 test runs against a stop watch, so I was not biased by sound or perceptions.
