Alan,
Go for it. That's what I put on mine. Budget Banks
I went ahead and replaced everything because my old exhaust was a PO mess. I went 3" into 2 1/4" sticks, added an H pipe just aft of the transmission. You may consider adding this H-pipe as well then connect up to your old mufflers. They don't cost much and should help with the overall "balance" of the system. No better time then now to install this.
I bought some "flexible" collector transitions which gave me enough play to line everything up using all of the old mounting points.
I would also recommend getting your hands on a cheap electric die grinder/cutoff. It'll make the job go more smoothly.
I had some real scares during the manfold removal process. This is the risky part. Once the old stuff is out the new stuff is pretty much bolt up.
