I filled it today with super unleaded, got it nice and hot and ragged it! still no nice exhaust tones, so during a bit of skiving at work today I looked more into it.
Seems the SC and the 5 door have the same exhaust and can make the nice pops and crackles but the ST has got another silencer on each exit which seems to be killing it, disappointed as Vagsport could say this about the ST and I could have put the money towards a non resonated cat back.
Try zaustworxs res delete. I have one on my ST.
Had a go with the vagsport but I found the increase in diameter to 76mm then step back down to 65mm just attenuated the frequency creating a nice low growl at tick over and sounded like
cupra mode on acceleration however it creates very muted dsg upshifts and drone at around 70-80mph which was a real let down and caused me to remove it.
Zaustworxs one is slightly smaller 63mm, the drone is very low at 70-80mph but quite noticeable on tick over in sport mode not so in comfort. The acceleration noise is not as loud.
However overrun cracks and pops are quite noticeable and the dsg cracks are brilliant always brings a smile to my face. Sounds slightly louder than a stock hatch. Bit more grown up IMO.
Here’s a comparison between the two with the vagsport on the left and zaustworxs on the right. Both made from stainless. Bare in mind I had just cleaned the vagsport one. These are my personal opinions nothing against vagsport there work is amazing, just doesn’t work well for the ST and the price is just too much for what is basically a stainless pipe.
