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

Metal or ceramic? What causes this?

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Metal core

 

Magnaflow i think they where

 

Just can not handle the flow

 

Heard of lots folding over,  even my mates cammed ls2 folded over twin cats

 

Think they where x force ones

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

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

Yep killed one of mine (not quite as bad as that) with the crap initial tune/tb sync I had running mega hot on one bank…

No Decell fuel cut doesn’t do em any favours either…

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

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

Part of having a high hp modified car, stuff breaks, nature of the beast…

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

That’s exactly right Gary

 

if the cats are breaking that much better then the rear axels that where breaking last time lol

Drive, break, strengthen, drive break, strengthen, rinse and repeat…

Good thing my VS isn’t required to have cats……
