ya i still have the stupid autolube oil pump on my blaster, and adding the seafoam worked out great for it, didnt harm it at all, i still had to remove my exhaust pipes and clean them by hand i just poured a bunch of that sea foam in both pipes let them sit for 30 mins, and then took a wire brush to get the rest of it out, i also did use a low flame blow torch to burn some of it off, but it worked great, pipes all basicly brand new, except still gotta repaint them(had to anyway before) with the high temp paint make them look all shiny lol, but ya if you do what the guy above me said you will be fine, if your still worried go to a performance shop and ask...they can definnetly help you out
