I would think it would need some modification. The oa length on the stock muffler that the mufflex is designed to replace is something like 36-38 inches iirc. Alignment of the pipes after the muffler might be different too. Might be easier and cheaper to buy a 14 inch and have your local shop do it. My shop quoted $135 in parts and labour if I brought the muffler.
