I just recieved my 3.5" mufflex cat back with spintech muffler. Im wanting to install it real bad. Is it something that I can do myself. I might be able to get ahold of a lift for a short while. Will i need any welding equipment? I was looking at the brackets and they didnt look like they hoocked up to standard exhaust hangers... I could be wrong? Pretty cakewalk install or what? Appreciate any comments..
