Now that sounds like a tuned GTI should sound ![drool :drool:](https://www.mk5golfgti.co.uk/forum/Smileys/newsmileys/drool.gif)
How easy would it be to make it interchangeable, so a cat could be swapped into it for the MOT? and then back out again?
Very, just need a Cat pipe and a de cat pipe made up to fit into your down pipe.. Would cost about £80 to get it done at Exhausts UK.. I asked when I had the S3..
They would be flanged so taking them out and swapping would take about 5 mins..
