Lol, like your style bud, I am a big lover of loud good sounding exhausts. Before decatting, I had the resonator delete done and the sound went up a bit but not that much, but when decatted......f#ck me, it's a entirely different league. Thrashing though the revs to 5k is like supersonic loud, can only image with a K1 decatted it would be mental, might be worth yt-ing to see if you can find any clips (if you've not already done it). Also read the K1 tends to drone badly when decatted.
