XrayActual: Yes, that's what I was thinking - hence my reference to an excessively aggressive cam.
(A bean can ricer exhaust would be cheaper and probably give similar audio results.)

Cj3636:  A better "sound of power" (in my opinion) would be to modify the exhaust system to provide a deeper, throaty rumble like it actually has power. As ken suggested, start with removing the secondary cat.

as I'm sure you know, typically - racer cars are tuned for very specific engine range and use - they tend to lose performance at lower RPMs, and coming off the throttle a lot of that excess fuel in addition to an unrestricted exhaust usually results in some pops and even flames. highly tuned cars will do it

 

on the street... it just comes down to wanting sound like a racecar or look like one - we all have our fun somehow... scaring the heck out of neighborhood dogs is one way

Funny you should mention that - when I think of exhaust pop and bang, I think of classic European sports cars : )

I am not aware of any mods that will specifically add pops and bangs, but exhaust mods are your best bet.

The pop and bang is actually programmed to the car by the software in the computer. You may be able to get some pop and bang by modifying the exhaust, but can't guarantee it.

You can start by removing the secondary cat / resonator in the B pipe just after the flange. There are no sensors around it so it does not affect the emissions sensor in the car.

Some have also removed the muffler - since there is a turbo and a cat in the downpipe, the sound is not 'over the top' without the muffler, but that is subjective so proceed at your own risk. Of course, if you step on the gas aggressively, it will  be loud.

I would wait on removing the cat in the downpipe - it will cause a check engine light.
