I just baught 2 new pipes a fmf powercore 2 pipe, and a fmf sst expansion chamber i just tried the powercore 2 out today and its awesome i shined it up no major rust. but the expansion chamber has a couple minor dents on the inside and a bit of rust i was just wondering if anyone knows what i could buy or use to remove this rust. thanks.
scrotch brite pad, or green scratch pad like the wife uses on pans and WD-40 works great. Also Lime Away or some sort of mineral desovler works great on burnt on mud. When its all clean spray it back down with WD-40. I think it adds a desent smell on start up too.
