My friend has a 00 Civic si and after he installed his headers his engine started making a weird sound. Any ideas? Search didnt turn up anything, maybe i didnt search hard enough

 

Ghosts???

 

a leak? did you change the gasket?

 

if its a popping noise its a bad seal..its the sound of expanding exhaust..a hissing sound usually the result of increased exhaust flow

 

First check to see if the bolts are torqued correctly, then retorque them after he drives for a while. Also sometimes the increased airflow goes through a poor seal at the header/cat converter where the donut thing is, which happended to my car too. I just bought a new donut gasket and the noise went away.

 

maybe its because you installed too many of em

you question is vague, be more specific... what does the wierd noise sound like?

and also what make of header did he install?it the bolts on the header flange are comming loose from the block then use some loc-tite and that should stop that. one or two drops is all you need.

or maybe your civic really is haunted. if you start to hear a knocking sound then they want to be let out of the hood.
