Nobody's responding?.... Humph!...
Several members here have wrapped pipes...
From what they've said,... They do get a smell when wet... one described as a burnt pop tart...
he may have been eating a PBJ during install...
They will also cause your pipe to blue very fast, and if you ride in wet a lot, rust...
But, if that look is da'bomb, you'll get some experienced advice on, How-to, here... eventually...
I don't understand where everybody is today,... can't be riding...
it's too cold out there...
(EDIT)...
and now Lancer beat me to the response,... just 'cause I said that... Look at my post time,... I started first! I'm just a little slow...
Short bus'n'all........
