I need a new exhaust...dealer estimate is around 400 bucks, looking for any suggestions for alternatives which might be around the same price but better or the same but a cheaper alternative - its for a 99 2.7L 4Runner. Thanks in advance for the help.....also forgot to ask, easy job to do myself? If its just undoing a couple hooks and bolts and reattaching I think I can handle it in my garage but I've never done it before so I have no idea. Thanks again.
