I had my muffler cut off in the tig and it weighed 8kg.
It does sound louder than stock but i have Stage 2 so i was expecting it.

If you want power out of your cat-back system apprently you want to remove the resonator as it reduces the air flow through the system after the downpipe/cat.

The main gain will be from upgradinghte downpipe which will allow you to go to Stage 2 tune however you wil need to have the car re-mapped for this to work.

The weight difference was not so noticeable to me but i noticed the 12kg difference when i upgraded my wheels

From experience from other turbo cars, any exhaust that reduces backpressure will get gains in response and slight power increase due to boost rise. The AFR might run leaner but it will be fine with factory tune as they tend to make it richer to avoid detonation by cooling the pistons and also for minor variation such as exhaust changes. The key is obviously whether the backpressure on the stock exhaust is high or not in the first place. Being new to VW, I am not sure but the Mitsubishis and Nissans Turbocharged vehicles that I have had in the past all behaved the same after exhaust change. with tuning as well obviously will bring more gains
