I can tell the difference on start up. Truck roars to life with a very deep growl. Butt dynos are subjective, but I feel at between 3k and 4500 rpms it pulls better. The problem with any expectations of measurable power gains is it costs money to tune and dyno. We are the first ones to put these on our trucks. DT has been producing headers since the 1960s, so I think they have a pretty good idea how exhaust flow works. Looking at a cross section of the OEM crossover tells me that my engine will breath a whole lot better. Is this enough juice for the average person to go through all the aggravation and expense? Not for most. We don't have the luxury of dozens of performance aftermarket parts being produced and tested like say a small block Chevy or Ford. We do these mods in the hopes that our soccer mom SUVs will gain some punch. Toyota performance costs money unfortunately. If someone wants to donate a stock V8, do a baseline dyno run, put 33 to 35 inch tires on it and do another dyno run, put intake on, tune and dyno again, put exhaust on, tune and dyno again, we would have concrete numbers to advertise for these products. You see the logistical and financial problems this would present for most of us? Hell lets put a go fund me account together, buy a truck and donate it to DT and let them experiment for awhile. Even then there is not enough interest for DT to put much R&D into a project like this. These pipes make power, but until some real world proven numbers are published, there will always be people who disagree that they make any power at all. I'm sure someone will disagree with this post as it is. There would be people who disagree with actual dyno numbers being accurate. This is not like an interior led swap where you can take a picture and show everybody. It's a leap of faith I was willing to take and have been happy I did.
