Difference between milltech and cupra exhaust

[Smee]

Hello

Have a wierd question but what is there difference between a full milltech exhaust and me decating my cupra exhaust.

Will the flow be the same. Only reason I ask is to upgrade to stage 2 you need filter and exhaust but I like the cupra one and it's not loud obviosly I expect it to be louder decated

Just trying to work out where to save money

If you decat a petrol car you'll fail an MOT on emissions. I have a full milltek system with sports cat and it flows soooo much better than standard cupra exhaust. If you're worried about noise you could go for the resonated version which is quieter

Millteks on these diesel engines make them sound quite nice. I would imagine a decat would just make it sound like a louder diesel?
