faussy Posted June 20, 2018 Report Share Posted June 20, 2018 (edited) Scotch brite (grey) and water works great for me, although some may be aghast at such a suggestion. I should probably add that this works with my titanium 2T exhaust, the hotter 4T exhaust may cause it to burn on extra hard Edited June 20, 2018 by faussy Quote Link to comment Share on other sites More sharing options...
sirdabalot Posted June 20, 2018 Report Share Posted June 20, 2018 As above, or the pan sponge from the kitchen sink. Quote Link to comment Share on other sites More sharing options...

Rapidroy Posted June 21, 2018 Author Report Share Posted June 21, 2018 4rt with titanium downpipe hold it about 1000 rpm higher than tick over then light a cigarette of it (red hot) Quote Link to comment Share on other sites More sharing options...
Rapidroy Posted June 22, 2018 Author Report Share Posted June 22, 2018 No need for a re-bore I have most of the brown stuff off I found alloy wheel cleaner and green washing up pads to be the most effective But still not great Quote Link to comment Share on other sites More sharing options...
boner Posted January 15, 2019 Report Share Posted January 15, 2019 I use Harpic Power Plus toilet cleaner... Heard about it years ago, and was very sceptical... but gave it a go... bloody magic! Paint it on... wiggle it about with a brush, leave for 5 mins - hose off. Exhaust looks like new! Used on Akrapovic titanium headers, no drama.

2stroke4stroke Posted January 16, 2019 Report Share Posted January 16, 2019 I'll second the Harpic - returns stainless to silver when it discolours to brown. Saves hours with Solvol. Quote Link to comment Share on other sites More sharing options...
