I just had the Belanger headers and high flo cats plus the Belanger cat back system installed on my ACR and it was WELL worth it. Awesome increase in performance and much louder which is what I wanted. The best part too is NO cel even without the Mopar PCM. Had it professionally installed though by a Viper tech.
What I found is you can get about 2500 miles on a set of the aftermarket cats before the efficiency takes a crap and you get a CEL. I have yet to find an aftermarket cat that is anywhere close to the longevity of the stock system. Maybe that is why the stock set up is two rather porky cats for each bank.....you really can't expect an aftermarket cat the size of a grapefruit to last very long with 600 hp blazing through it. I'm figuring because of the smaller size, they "wear out" exponentially faster than the stock set up.
