Literally just finished putting an xpower janspeed backbox on my hatch.
I went from standard to stainless decat and centre section. Sounded good and gave a good little kick.
Then I added an ITG Maxogen. Sounds brilliant nice induction roar and awesome sucking noise lol! and the engine seemed to love it!
And now I've added this! Haven't even started it since fitting so will have to wait and see how it sounds!
