Aa requested by smithy756 here's a cople of vids of 1.8 n/a 20v running a straight through from center box back
Thus first ones on idle but sounds deepen than on the vid!
Second is pretty self explanatory again deeper note on real life!
And lastly from inside the car, it's a lot quieter!

Some people are like slinkies, no real purpose in life, however..............
If you push them down the stairs, they always manage to make you smile!!!
