The purple trace is stock pipes, the red trace is Tyga GP pipes, info all here.

I'll leave it up to you if 1.5bhp and 500rpm overrev is worth 9bhp in the middle.

OK, but on the flip side, at the start of that extra 500rpm (@11,500rpm) TYGA's are 10hp more than the stock pipes.

Are you going shopping or racing?

I know I shouldn't say this as it's very bad marketing, but if you want an easy ride on the street then stick with stock pipes. They're a lot heavier than race pipes, but they're less likely to upset the neighbours with a load of ring ding dinging in the morning, and offer good driveability in a real world situation. However, if you're going racing, or you're a track day lunatic then how often do you spend wobbling around between 7~9,000rpm?

Just my opinion.
