so have u tired taking it off and cleaning it yet?

also those pipes sometimes they can come lose make sure their on and tighten the clamps, but from what i can see it looks like its on fairly tight hahaha.

if non of this works you may have to try other things, does the car only run shit on idle or does it behave weird when throttle is applied too, sometimes spark plugs and the leads need replacing too, it will missfire
