Does anyone know what they do to achieve this? Ive tried contacting the company (ASG) and had no response. They take the OEM system and modify it somehow. I just don't know what they have done. It sounds perfect tho. Ive searched on here but any of the sound clips / videos Ive seen / heard dont sound anything like this.

Oh and hi!

Hi Dialekt,
Had the backbox removed and straight pipes inserted is my guess. A few places do this I think. As you say, sounds good but would it get annoying day in day out? Don't know myself & I couldn't afford to do the conversion right now even if I wanted, which makes life easier from my point of view.
Cheers,
Robert.

+1 on the backbox delete.
