well i have a chance for some fairly cheap mufflers and dont want to buy a full catback right now but the mufflers are 2.5" and as you know stock is 2.25" so how hard is it to cut out the stockers and weld in the new ones? should i just take it to a shop and have them do it or try to have a friend that is a decent welder try and tackle it? what would i need to do to make up the size difference if we try to do it on our own?
