Is there a reason for buying a cat back system over just getting some new mufflers installed? I am just curious as to if there is some performance difference or just personal preference.

Cat-back systems are mandrel bent as well.

Yellow94GT never touched anyone's sig or banned anyone, so I'm going to quit spreading that rumor. It's not like I have any proof anyways. All yellow94gt and other mods have done is volunteer their time to help other people buy/sell parts, learn how to make their cars go faster and meet fellow enthusiasts. I'm a hater, but it's hard to hate on these facts. I have saved hunrdeds, maybe thousands of dollars here buying and selling parts over the years alone, but I don't care, this website owes me damnit, and I'll piss on it as much as I want. Us haters gonna hate. Why contribute to something when you can take for free?

Oh yeah, this isn't my website, so no one has to ask for my permission to change my sig. Hell, not like I pay the CAFORDS bill, so why should they need my permission to put what they want on their site? We're all guests here. Maybe some of us should start acting like guests or leave?

It depends on your combo. If you have a basically stock setup you won't see much if any performance difference between a good set of mufflers and a cat back. If you have a build motor or are running a blower setup (especially with H/C/I) then you will see a difference. This is assuming you have headers and a matching H/X pipe.
