Exhaust expansion

sylonien · 10-14-2015, 09:18 AM

Did a recording for my new exhaust.

Whilst editing I noticed how much the backbox (or the whole exhaust) expands in the short space of time from a dead cold start to the end of the cold cycle, within 1 minute or so.

Weird eh?

I'm sure it'll extend even more once it's fully hot after some run, but that was right after the cold start.

Stainless (even low grade stainless) expands a LOT when it heats up.

maybe the rubber hangers get warm too

That's just your exhaust getting a chubby. Also, where's this 'video' you made?!
