Hello all! I currently have an x pipe on my car but am looking for more! I am very interested in Roush catback but I’m not sure if I should just buy the axle back since I already have an x pipe. X pipe was made for me by a local shop and sounds pretty good! Let me know what you guys think! thanks!

Unless you want to get rid of your x pipe don't buy the full catback
I’m fine with getting rid of it I’m just wondering Is it going to be the same as the catback system? X pipe +axle back ?

Basically the same. But it would be nice having all one piece of the same shit instead of a custom piece in the middle

What diameter pipe did the shop use for the x pipe? I believe the stock diameter is 2.5" for the exhaust. So they might have cut the 2.5" and used 3" pipe for the x-pipe with a 2.5" to 3" back down to a 2.5" pipe. The cat backs usually use 3" from the header flange all the way to the mufflers. I believe most of the axle backs do the same. I had a pypes muffler delete system installed when I bought the car and hated it. Loud but not a nice refined loud. Noticed that it went from the stock 2.5" to 3" and was all booger welded together. So I went with a full cat back 3" system.

I'm not sure if it makes a difference between getting necked down then back up or anything, but it's definitely a lot easier with bands if I need to remove anything now.
