Getting ready to order some mufflers for my 99 GT,as I understand it the stock pipe diameter is 2.25. My question is do I order 2.25 or 2.50 inlet outlet size?
Plan on having the mufflers welded on.
Thanks

2.25" if you're going to use the stock piping.

Stock diameter is 2.25. Most aftermarket (Flowmaster, Magnaflow etc.) are 2.5 with 3" tips.
