    So the manta has been running a little off lately, mind you Iv only driving it a few times since it was last tuned

     

    but it was down on power and felt like it was shutting down

     

    anyway I removed cats yesterday for a inspection

     

    So these are 3.5 inch 100cpi cats that have done less then 300km total driving distance

     

    1 was jammed down the pipe and caved in and the second could mave back and fowards about 150mm and also caved in

     

    100cpi cats do not flow as good as people have told me, if you haven’t guessed the last cats on pacemaker extractors I was a little smarter and may have removed some parts to make them flow better so I never had this problem

    I’d be chasing this up. That’s pretty piss poor. The next best thing from 100cpi is nothing at all.

    I thought this happened when the AFR too rich can overheat them ? I would be taking them back as Mr Cava says above

     

    • Misfires
    • AFR Cylinder imbalance
    • Excessive engine or vehicle load
      – Fuel delivery system or fuel quality
      – Sluggish (worn out) O2 sensors
      – Excessive backpressure
      – Low compression
    • Poor spark, or weak ignition
      • Bad exhaust valves on the engine
      • Fouled plugs causing unburned fuel to overheat the converter

    It’s never run that rich at all, we had the old tune and tuner to be able to make a base tune for when I fitted LS PCM and it ran pretty dam sweet straight away,

     

    slightly rich but nothing enough to distroy cats

     

    couldn’t really care to be honest, when I installed them I really did think about putting flange on both sides of cats for when this day comes but then I decided against it as less joins means less leaks so my cats are welded to a 900mm of 3.5 inch pipe

     

    ill just go from 100cpi to 1 cell all up, luckily e85 burns clean :yes:
