The dimensions are 2.25 in and out and there is a cat on there but it's straight piped it sounds like a v8 I love it I bought the muffler at my local advanced auto parts

 

What do you mean by strait pipe if there's a cat and muffler?

Is the cat stock? only aftermarket part on your exhaust is the muffler? Sounds beautiful btw!

 

Ya exactly that it's the stock cat just a smaller pipe stuffed in it so it acts like there is jut a straight pipe to the muffler from the muffler I put a factory section I got at napa for 50 or 60 bucks I think then welded everything and thank you I get a lot people asking me I I swaped the motor to a v8 lol

 

Here's a few pics of what I did neve took a pic of the cat but here is the rest
