Makes zero sense to me when the 17513 is a direct replacement. Wonder what their reasoning is? I've done this a few times by the way, 17513 absolutely fits!I just ordered them, they use the below part #

Haha, who the hell knows...unfortunately that may be the case. I think it's definitely worth a phone call though, maybe save you a few dollarsI agree, I don't know why they don't use the 17513. Maybe they want to charge for the extra work?
Here is my take on them. First Flowmasters slowed my sons car down almost 2 tenths when all capped up. I prefer Dyno-Max and if you just want a good sounding not to crazy loud car use the Dyno-Max Turbo's. But as for me I wanted the most performance you can get out of a muffler as I race my car just as I drive it through the full exh so I went with the Dyno-Max Ultra-Flows as they are basically a straight through muffler and I would guess dont slow you down much. I always race my car through the full exh system and I have 2" TTI headers and a 3" system with the Ultra-Flows and I love it. I have never uncapped my car to see if its any difference but I dont think it would be much if any. Bottom line to me is if you want the best performance muffler then use the Ultra-Flows but if you dont care if the muffler slows you a little and robs a little HP then use the Dyno-Max Turbo mufflers.
