Hi,
As long as you have a set of ramps or jack stands, you should be able to. The convertor is bolted on. The drawback to doing it yourself is that you will have to buy a factory convertor. Aftermarket convertors are universal and have to be welded on. Check around, you might be able to get an aftermarket one put parts and labor cheaper than the cost of just a convertor from the dealer. To give you an idea, I charge $250 parts and labor for that job
