There's about zero difference in power on a NA car, and cars with cats sound and smell better.
I actually gained a substantial amount of hp from my x pipe. I dunno how.
Oh, and I have the off-road, and I love the smell a lot better (it is all based on preference) and I love the hallow sound of the exhaust (again, preference).
Most people will tell you to just get exhaust depending on your sound preference:
If you like a hallow ripping sound, get an O/R X. /* some people say it's a bit raspy with 2 chamber mufflers, but I don't know what they're talking about...I thought that's how Mustangs are supposed to sound */
If you like a solid ripping sound, get an X.
If you like a hallow rumbling sound, get an O/R H.
If you like a solid rumbling sound, get an H.
If you like a hallow mix between the two, get a O/R ProChamber.
If you like a solid mix between the two, get a ProChamber.
If I am wrong on any of these, someone please correct me.
