Xforce blown cats

[gr33nbastad]

So, about 16,000 klms after install of a full Xforce system with varex mufflers, I start hearing a rattle in the right hand muffler and find a big chunk of cat flapping around, and the left hand side valve completely stuck shut. Pretty pissed about this crap, warranty claim PITA paperwork still to come. PS: car is stock with a tune and CAI, thats all. WTF Xforce???

Wow ive never seen a metal cat fail before,must be **** quality.

I've seen many fail for various reasons both expensive and cheap brands.

Is the car lowered as they can crack on the inside when you hit a speed hump or pothole.

Unburnt fuel can cause a problem as can regular short drives.

It's stock height, mostly takes me to work 20ks away on the highway. I suspect the tune too given comments on some other forums.

thought x force would’ve had this sorted by now, I’d be pissed off to

Faark! I have my LSA blower waiting to go on next! My tuner did say that the cats won't handle that.. which has me worried about running cat-less. Is there nothing out there that can handle a bit of increase flow?

Might be better off running ceramic factory type cats then.

i am currently running 100 cells i brought from Motor Torque at Brookvale NSW, they source there own metal cores and then have them made, haven't had a problem since. ( 6000 thousand km's and 4 dyno runs still going strong)

problem is that will limit the boost you can run especially on a ls3 , also i have seen ceramic cat disintegrate and fly out the exhaust after rattling around for a while, also have been told that the broken cat material can be sucked back into the cylinder when backing off not a pretty sight apparently
