Good evening,
My 182 has an exhaust leak which whilst I have had the precat joint replaced with new genuine it still remains.
Main symptoms:
1. Raspy blowing when cold and under load
2. Whistling above approx 4-5k rpm on wide throttle, sounds like coming from below gearstick area
3. Quiet tinning sound from around middle of exhaust at idle when warm. Increases in repetition with slight increase of rpm above idle and is definitely nowhere near the engine area.
4. Seems to be lacking go at the top end of rev range, like power dropping off from 5k. This is in comparison to another 182 running ktech exhaust.
The exhaust is a Scorpion RS192 after cat system.
Any suggestions? What are the symptoms of a cat breaking up? I presume this could cause gasflow problems hence the perceived reduced top end power?
Thanks!
