assuming walang cat converter, di ba nasisira din yung mga laman ng muffler kung binubugahan nyo ng tubig? pati narin sa resonator? fiber wool din naman gamit nila to suppress sound sa diesels diba?

also, i'd think doing this would make your whole exhaust system prone to rust (unless it's made from stainless steel) which will thereby make it break faster.

i'm no diesel afficionado pero i'm interested in finding this out.
