Default Exhaust smells like burnt popcorn, at idle smells sweet

Exhaust side smells like burnt popcorn, at idle the interior smells sweet.

Milled head around 11.8:1 compression, with Comptech 4-2-1 header, Spoon N1, 16 degrees timing at the distributor, B&M fuel modifier bumped to 52PSI, everything else stock. B18C5 motor.

Never like this until I started modifying.

Any ideas? Possibly a high flow cat is in order?

Mine smells like sulfer after a WOT trek into VTEC.
Other than that it just smells like chicken salad around town.

What you're smelling is burning Rice. LOL

Seriously though, when one of my ricer friends put a huge can on his Civic, it smelled like fried doughnuts.

Edwin, my exhaust smells after use as well... I thought it is just because the unit is new. If you want, come over, take a SMELL... if it’s the same odor then it’s the exhaust and not the monster you have camouflaged under the hood.

A sweet "maple Syrup" smell to the exhaust usually indicates your burning coolant.
The popcorn smell on the otherhand....?

As many people had already said, sweet = burn coolant.

Thanks for the replies guys, I will have to check all the fluid levels tomorrow to rule those things out. No leaks anywhere to be found.
