finally got one of the cats out today. took alot of hacking though, man they are tough!
next I need to smooth out the interior of the can by removing any excess metal.
then Ill buy a perforated pipe and run it straight through to some new end caps Ill get made up (possibly the same as a T4 or a staintune design).

Ill wrap the perforated core in fibreglass.

but for now ill just run the standard ends and the big hollow interiors of the cans...
