Just wanted to know if I could use Muffler piping...get some bent at the muffler shop..2.5inch. I know its steel and keeps the heat and shit..but i think its better than those cracked stock piping. Is muffler steel to thick ?? what metal do i get if i want to make a lower ic pipe..can i just bring my lower pipe and tell the guy...bend me this in metal ??
and..2ndd...correct me if im wrong, lower ic pipe should be aluminium if possible and upper should be steel with ceramic coating ??
