Blackthumb Exhaust Pipes

Do loud pipes save lives? I can't imagine it's a priority for the blackthumb clan - the safety that is. They're dead keen on loud though! Smoke stacks, tail pipes, mufflers, that sort of thing. Getting billowing clouds of awfulness into the air seems to generally contribute to the project in a way that they find very agreeable.

Dimensions! The lengths of these vary between 3.5cm and 5cm or about 1.5" to 2" for you Imperial bods.

This is a set of 5 polyurethane resin exhaust pipes. Sculpted by Benjamin Fox. Supplied unpainted. May vary slightly from images shown.
