Finally washed the car + found the right exhaust outlet is just cosmetic ! The left one has both pipes tucked away within. 

Not fussed really, but then surprised when today parked next to another mk3 + spotted it was different - one exhaust pipe tucked behind each of those outlets. What gives ?

It was a Petrol. I assume yours is diesel.

Mines a diesel too, you need to spend some coin and get a decent system, the good thing is its already setup to take a dual box as its the same configuration as the petrol, you just need the correct tip on the RHS and a new exhaust too.

 

Do these twin exhaust pipes add improvement or is it purely cosmetic.

To make an improvement in performance on a diesel you will need to make other changes to the inlet, fuel and mapping as a minimum to increase the air flow sufficiently that the stock exhaust will offer a restriction.  A standard, diesel engines 'breath' quite freely and the inlet and outlet systems provide very little in the way of restriction.

Adding two back boxes is a cosmetic mod on a diesel. Don't think it even does much to the sound, does it @JohnnyType2. That's why you've the sound machine underneath isn't it?

 

You'd have to do modifications further back for it to make a difference. You're talking manifold, the catalytic converter, the DPF and then all the pipe work between. The extra back box just gives the current gas flow a choice of two exits.

 

Having said, it is something I do wish to do, as I want both sides to have the fumes coming out of

yes correct and all that work is already done, 3" down pipe, cat and dfp. There's no difference in sound with a dual back box so the kufatec unit does make a huge difference and can be turned on/off as well.

Forgive me sorry, I have tried to search through your posts. Is your new exhaust system resonated?
