Can anyone who is running this setup tell me how much louder this is compared to Comp/cats. I want to order but just dont know which way to lean.

 

It is night and day difference with the cats off. I had just the axlebacks at first and then went to the o/r pipe later and don't regret it one bit. With just the axlebacks it is not much louder than stock but with the o/r pipe it is very loud. What im trying to say is that I would definately go with the o/r xpipe. You wont regret it
