Of course, anyone can prove me wrong, by putting their totally stock Puma on the rollers, remove mufflers or whatever, & then do another run,..
It has been shown by well regarded tuners in the UK, BAS, Alive, etc etc, that the way to go is ECU remap, & for anything over 160hp an intercooler is required. With hot Aussie conditions, I'd say an intercooler would be mandatory.
But for normal upgrades, they don't touch the exhaust, simply because, there's no measurable gains to be made.
Finally, & I'm not telling anyone how to suck eggs, but a "chip" is not the way to go either. There are "chips' about, several of them, that "piggy back" the standard ECU,......I wouldn't touch one. Only way to go is a remap of your ECU by a reliable tuner.
