Does your 325 crackle and pop on overrun? Mine does when I'm coasting down from say 3k revs. It sounds great, but I'm starting to wonder if it means something bad is going on, cos I can't imagine its standard on FI engines!
The engine is stock, and the exhaust isn't anything special.
Please help with my paranoia!

Can be caused by a very lean mixture on light load whereby the fuel doesn't get ignited by the spark and builds up in the exhaust until something makes it go pop.
That or it's still burning when the exhaust valve open so it kinda pops out.
Shouldn't worry about it too much unless you're getting really big bangs?
