TDi exhaust...from single to dual

[010GolfTDi]

I want to dual my TDi's exhaust for the main reason of how much cleaner it looks.
Would the action of replacing my stock catback with something like this...

Would that be negative for my car in any way?
I'd be adding a dual exhaust rear valance.
Not necessarily looking for anything louder than stock, but OK with that if that is the result.
Will it increase or decrease my MPG?
Thes the only true modification I wanted to do besides for exterior upgrades.
Any suggestions...do's or don'ts?
Thank you

Won't hurt anything, but might help power and mpg. I like the dual look, I might do something like that on my wagon's, thank's for the link, that's a good deal.

I did the modification to mine. No noticeable change in sound or fuel economy or performance.

Just the noticeable impact to your wallet, right?

My wife backed up onto a rock and I had to replace the muffler and rear valance anyway so no cost difference really.

Looks super sweet!

I thought about doing this to my MK4 Golf but routing the second pipe from the front of the muffler and using an electric cut-out to open it up so that I can get rasps and whistles at the touch of a button.
