If You put on a high flow cat, muffler, and a cold air intake You might get 5-10 horsepower. You'll probably need some exhaust pipe, and some exhaust tips to install the muffler along with some clamps, and hangers.
You'll just have to buy maybe some u, or j bends, and cut them where You need them, and connect them to the pipe going to the muffler, and then on the exits of the muffler. It would be better to weld them, but clamps would work too. then put You hangers where You need them.
If You've never one this before You might wanna go to an exhaust shop, because They'll have the supplies You need, and will do a leak free seal on all the connections. They'll prolly have some exhaust tips to choose from too.
