anti lag with cat?

[BlackAWD]

Sounds like a blown out cat to me but I'm still curious.

It really depends what you are talking about. If it is a two setup like is stock on the evo the cat will live if it is full rally anti-lag it will live but you might want to move the cat to the back like the rally cars do because i don't know if it will make it up front.

Personally, i would remove the cat if you're planning on using anti-lag very much. The whole point of anti-lag is to turn the turbine area into a flame thrower and to let the gasses from that flame out as fast as possible spooling the turbo. A cat will only slow the spool if it does live through it. I would say that if the anti-lag is setup right you may get away with using it through the cat, but moving it further back may be a good idea. Some times the AL feature will cause a lot of popping and loud backfire style pulses that would most likely be damaging to the cat, i would just take it off and run a "test pipe" all the time unless going for an inspection or emissions test.
