This is just crazy. I saw this in a parking lot. It is big enough to wear on your head as a helmet! Anybody seen these before?

 

Looks like a 05ish GMC 2500 with the Duramax... prolly a 4" or maybe a 5" si/so with a 6" tip. I've seen one here and there... look pretty good

 

 

Fire that baby up and it would be lit up and smokey

 

@Stealth It is at the smallest a 6 inch tip. My crappy phone pic doesn't really show how massive this thing is!

 

That is quite a bit bigger than a 6" tip.

 

A timeless internet classic comes to mind:

 

lol^

 

Not even close to being the biggest. Try an oil rig diesel engine that has an exhaust on it that you can crawl in. Cylinder holes for each piston a large man can crawl thru. RPM ranges from an idle of 500 to a max load at 880 RPMs. And yeah, they use chrome exhaust tips....but it requires a flatbed truck to bring it to the engine. Now that's a big tip!

Looks like 1muddytruck found a pic of one.

 

looks like an 8" exhaust tip to me, mine is a 6" exhaust tip(choosing words carefully)

 

 

There's a older superduty that comes around my block once in a while, has a stock 3"(?) exhaust underneath, and the guy through a atleast a 10" tip on it. Looks hideous. I only hope he through it on there for comedic reasons.
