Ok, so I've recently been looking at x-pipes systems for my mustang. But, I was just wondering which kit you guys recommend. I want to replace the cats and everything at the same time. Right now I'm not sure as to if I want an off-road pipe or high-flow cats. I was looking at the SLP and Magnaflow kits because those are the only two I have seen before. Any suggestions?

 

Leave it stock. Ford did a good job on the S197 exhaust system in which the only reason to go w/ an x-pipe over the stock h-pipe is for sound. If I were you, I'd use my money on items more worth it, like suspension. However, if you want it for the sound, keep it legal and go w/ the Magnaflow kit. They make the best cats and their cats flow very well.

 

Yea I pretty much do want it for the sound. I know my dad had an off-road pipe on his mustang, but switched it out so it could pass inspections and it sounds almost the same with high-flow cats. I already have the tokico d-spec on her way, so I was just trying to find something else for Christmas. Thanks man.

 

You can lower the car if you do not want to swap mid pipes.

 

Yea I want to, but I'm afraid if I lower it too much that the 20-inch wheels I want to get won't fit or that the side-exhaust from the C-500 kit will drag. So I'm just scared that it'll be too low.
