Yes, the resonator probably DOES restrict exhaust flow and increase backpressure as opposed to a straight pipe or a freer flowing resonator but who cares! I would be willing to bet big bucks that the cats create far more backpressure.
When trying to free up power by reworking the exhaust system one should remove the â??bottleneckâ? to gas flow first. As the resonator is likely not the bottleneck to gas flow why would removing it decrease backpressure?
This sounds like the same BS that exhaust companies like to spew. They often claim that a cat-back exhaust system will give palpable power increases on an otherwise stock car. That is simply not the case unless a particular car has one really, really restrictive exhaust. Most of the time power increases come from exhaust systems only if the cats are replaced or headers are used.
Replacing the stock resonator on an otherwise stock setup is, in all probability, a waste of money and a recipe for a really gay, boy-racer sounding car.
Iâ??d be interested to see dyno results or at least ETs/trap speeds with JUST the resonator as a variableâ?¦. Anyone?
some of this is true...although it has been proven on this site that with the replacement of the y-pipe alone will net you about 5-7(?) horsies at the wheels
