Is it worth it to put high flow cats on my SXT?
If anyone has done this, how did you like it? Did it help the engine breath better? Did it sound any better? Any power gains?
Most importantly, will it void warranty?
Considering a total delete of the cats all together was at best .08-.10 improvement in the 1/4 mile with no increase in 1/4 mile mph worth noting, one can assume, I think, that any variation of any cat is going to cost way more than any possible gains, you may pick up some with aftermarket cats and you may pick up some with srt cats- even then I would say no increase in power output based on the test I got no gain in trap speeds (cat vs no cat), you may increase exhaust efficiency down low removing some restriction to improve exhaust scavenging to pick up some low end torque numbers but it would be vary minimal to no gain, considering you would still have a cat to restrict flow/mess with scavenging efficiency.Any benefit to switch from se cats to srt cats?
