Has anybody replaced their ppp back box for one these? If so has it made a difference in sound or performance?

Am looking to change the ppp back box for something that releases the flat four burble slightly better.

Cheers.

 

The Afterburner Vortex will provide a significantly louder and deeper exhaust note. It won't dissapoint in terms of the burble. Performance wise it is better but the difference will be minimal and probably not noticeable.

 

Afterburner Vortex-totally grin inducing . got one fitted to my02 STippp. sounds nice inside but you really appreciate it when you are outside the car listening, meaning like when the wife is driving up the road you know what i mean

Looks wise.. its made very well and looks stunning...

Agree with above comments I changed my prodrive backbox for the vortex and it is significantly louder, not noticed a difference in performance mind you.

Takes some getting used to on motorways mind you but well recommended.
