Well, despite a full page of weird accusations at Havoc (when the original story is perfectly clear...), I think the original story is hilarious!!
Too bad you had to lose a muffler to teach the idiot a lesson...
I get the chuckles just thinking about some bouncing exhaust pipe, even if it didn't do any REAL damage, making those loud multiple thumps against his undercarriage as he clattered over it...
And the thought of him RAPIDLY dropping back... LOL!

And the thought of him slightly panicky as this 3-foot long metal pipe bounces under his car, and him wondering if it'll just roll smoothly by, or if it's going to pogo right up into his floorboards... LOL
