Today finally tackled the ugly blue titanium tips on the end of my M3's backbox. The agency power boxes come with only one option for tips, that being a burnt titanium blue finish. Little bit too racer boy for me however one came up recently on trademe for cheap and it was a V1 version of the agency power muffler which is pretty rare. Couldn't pass it up, the downsides being a bent flange and the ugly tips. With all the extra time in the quarantine, today I decided to drill out the rivets, take the tips off and see what I could do about the blue. Set up with a wire brush wheel and it came out awesome! Also seems the agency power logo is etched into the titanium so even after taking the blue finish off, the logo remained. Bonus. Pop riveted them back on with slightly bigger aluminium rivets I had lying around. If I had known it would come out this good I would have taken a proper before and after. Tips are still a bit wonky as is expected with early AP section 3's but major improvement.
