Hi,

I have a 1994 Integra GSR and was driving home yesterday when I noticed a major change in my exhaust note when I put my foot on the throttle, it sounds terrible, like a hole in my muffler or something, so I got out and lifted the hood and even when it idle's it sounds different, I can hear a slight click when it is at idle.

These are my mods:

2 1/4inch exhaust
DC sports headers
AEM CAI
5 Zigen muffler
type r clutch
type r flywheel

any input would be much appreciated.

Tim.

 

probably an exhaust leak. while the cars running, feel for air coming out around the connections. maybe just a loosenes / lost bolt.
