How much fabrication for Boss axle backs?

I really like the look of the 2 big tips and would like to pick up a pair I think.
I'm thinking my stock rear valence would need to be replaced with the boss one?
If so is that a straight up swap on a 14 V6?

What about pipe diameter? I suppose I could have an exhaust shop just make me a cat back that mounts right up. We have a couple really good shops in the area.

Pipe diameter is different. You need someone to weld it together.

All it is to make it happen is simply cut the inlet piping (the pipe that mates the over the axle piping and the muffler together) and swap tgem from your stock muffler to the GT500 quad tips. Then buy the GT500 rear valance online

My V6 has 5.0 mufflers on it haha and my 5.0 has v6 mufflers lmao

You gotta cut the bottom part of your bumper to fit the valance. It's all clearly marked where you need to cut in the back of the bumper so it's pretty straight forward. And as others have said, you gotta cut and weld the exhausts

On my 2011, the GT500 tips fit just fine with the stock rear valance. As mentioned, the back pipes of the mufflers will need to be cut off of of the GT500's, and the "donor" pipes of your 3.7 mufflers welded on to fit the stock pipes.

If your willing, search "exhaust", and my site name, and you'll find pictures of the welds that I had done. I posted this about a year ago.

I did the exact same thing you want to on my 13 V6.

13' GT500 quad exhaust on 13' V6?

My tip for cutting bumper is... you better have dremel or electric cutter.
Cutting bumper manually is way too much work and time consuming.

If using a 2012 or older GT500 single tip exhaust, all you need to do is:
-Cut the inlet pipe off of the V6 muffler (save this piece)
-Cut the inlet pipe off of the GT500 muffler (you won't need it anymore)
-Expand the V6 pipe diameter to fit the opening of the GT500 muffler inlet
-Hang muffler and weld V6 inlet pipe to GT500 muffler.
My installer welded it while the new GT500 exhaust was hanging in the car. This way he could align it and then weld it. Once it was hung, we never had to take it down to "align it".

If using the quad tip GT500 exhaust (from a 2013 or newer).
-Get a GT500 rear valance
-Follow instructions to install it on your V6
-Then do the same as prior instructions to have the muffler installed.
