in your experience guys, is it fairly simple for me to install the catback exhaust system (does it require any welding or is it all bolt on?).

Once i cut off the stock exhaust, can i ever weld it back on if i wanted to go back to stock or should i just throw it away or even sell it?

thanks

P.S. does the MBRP come with a muffler or resonator? and if i decide to have a shop install it for me, how much would it cost (per hour or per job?).
