I hope it woks well. At least we know @Claviger will give us some honest numbers whether good or bad. Over the years in different forums I've seen people claim crazy numbers, but never seem to want to post a dyno sheet.
BTW, I like my springs

But do you also like Hooke's Law?

To inject some proven theory in this thread. Pipes will flow 115cfm per square inch. You need 2.2 CFM per hp from the exhaust without inducing any sort of restriction for HP.

Knowing that:
2.25” - 208
2.5” - 256.5

Those are the numbers the two diameters support. The wrench in all of that, is the megaphone on the carpenter setups. When looking at the brute you can see the 2.25” section is incredibly short, where as the SW it’s longer.

This is why I will never ever believe they have the same flow, period.

Not on non-Hookean materials.

Talking about getting an exhaust in a small box, when my sidewinder arrived I was cursing up a storm(unusual for a Scotsman) for the box looked very small but when I opened it and put it together no parts were missing

plus the weight factor -the stock pipes weigh a ton and the sidewinder comes in about 12ibs(5.4kg) and as we all know the best way to get speed is to shed the weight.

Yeah, its so bizarre seeing something like an R3 exhaust in a small box.
