I've noticed the smell on my buddies 95 z28 with 52mm throttle body, headers, exhaust, intake, and ignition

I've noticed it on a few ricers with aftermarket exhaust

and I've noticed it on a mustang 94 - 98 or whatever the years are for the late 5.0's in the newer body and the 4.6's

Its like a sweet smell... i dont know how to explain....anybody know...

 

coolant? or burnt plug wires?? thats all i ever smell w/ mine..

 

hm...i dont know...the only thing i know about all of the cars is that they all had aftermarket exhaust on them. i know that one of them had headers on it...the camaro and i dont know about the others...
