i am fucking bored, so here it goes.
want to chop my ugly ass muffler to make it look a bit shorter instead of having a giant black dildo sticking out everywhere.
so here's the question. if i take ALL the insides out and pretty much just leave it as a straight pipe (with end cap to keep critters from crawling in, haha), will it damage the engine in any way? I know there's some mumbo jumbo working on back pressure and straight pipe would reduce it... by a lot, so would that be bad?
Or should i also chop up the internals to length required and leave them in?
