Can anyone tell me if this is the stock cat or an aftermarket? The cat back and downpipe are both perrin but I wasn't sure about this. Thanks for any help.

 

Looks like its aftermarket.

 

I'd say it's aftermarket.

 

its for sure aftermarket, the stock cat looks nothing like that... thats a high flow cat

 

me too

 

Well, a big giveaway is that you can see the welds where they custom fit it. Cat's aren't good, taking it off is better for your flow haha not legal, but if you track your car you'll get more performance out of it if you take off the cat.

 

Yeah I was just wondering as I was under there poking around while changing my oil. I live in Tennessee and I'm fairly sure you could have no exhaust at all and no one would say a word. God bless the south! Haha

 

Tennessee doesn't care haha.
