I was reading a threat last night which for the life of me I cannot find now where someone stated that the difference in horsepower and torque gains between a high-quality catted downpipe and an uncatted downpipe were only single digits. This surprised me as I thought the potential with the right tune and other appropriate exhaust components was much higher. How true is this? Does anyone have any dyno runs with both types of downpipes or have found any vendors that claim certain numbers for both types? I cannot find any. I have an AA catted downpipe on order and an uncatted aFe downpipe sitting in my office. I'm not sure I want to deal with a CEL ('21 untunable car) for single digit gains from the uncatted version (plus there are some issues with the aFe downpipes that makes me want to return it but they're being... difficult... about shipping).
Hope everyone is keeping the rubber side down!
