yep intake and exhaust done properly can be done by the manufacturer for very little and produce an instant increase in HP when the car is in motion. Makes me wonder why Toyo, Honda, Nissan have allowed the aftermarket community to reap so many millions of dollars that they could just have easily made themselves.
THis whole Scion approach to "aftermarket marketing" seems long overdue.

Even an expensive car like the Boxster benefits from upgraded intake and exhaust. IF DONE PROPERLY. The newest 987S Boxster added another 30 HP without increasing the engine size or any other significant changes to the engine itself. Its not like putting in a 3.6 but 30HP by just bolting on some upgrades is pretty darn smart of those Porsha guys.
