I have a petrol Cupra rather than a diesel, but I noticed my exhaust seemed much louder after I had the downpipe and sports cat fitted. Also, I went to Ultimate Dubs with Ash (
Ibiza 130 TDi) and his car sounds great, just a straight thru pipe from turbo back. No drone whilst cruising on the motorway but when he puts his foot down it makes a deep rumble, sounds great
I don't know why people pay so much for a Milltek cat-back for diesels tbh, the best sounding ones all have a mufflerectomy

It'd be cheaper to get a complete system custom made probably lol. I know of a couple of people who bought Magnex cat-back exhausts for their Ibizas and the first thing they did was go get the backbox removed and replaced with a straight bit of pipe. Millteks just seem to be far too expensive for diesels imo. I LOVE the sound of my petrol though
