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!
Does anyone know how they do this exhaust mod??

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.

Anybody know anything about what the company ASG does to modify the backbox?

DuckLakeView (forum member) done a bunch of backboxes for members where he cut open the standard box and welded in a couple of flexi pipes to the inside of the back box, I think there is a bit more to it its not entirely a straight through but I have one and think it sounds exceptional (vid below)
I find that straight up deletions do this sort of "thhhspppp" noise (like daffy duck) when revving whereas DLV seems to have eliminated that.
(in the OP video listen at 0:10-0:11 and 0:13-0:14 an 0:18-0:19 for the "thhhsssp" noise as the revs settle to idle)

Rather loud this here, but except the pops I think I like the sound.
I did a back box delete on my car. Bought a second box, cut the guts out of it(not for the faint hearted as I ended up borrowing a plasma cutter, but still had a lot of welding to do!), fitted some 2.5" flexi between the front and back pipes and welded it all up. I does sound good, but I normally fit it for a few months then swap it out for the original box for a change. All in the job cost me £70 (£30 for second hand box, £20 for 1m of 2.5" flexi and £20 for exhaust joining clamps), so a relatively cheap mod.

+1 on the backbox delete. I didn’t mess about with changing the back box, just got a local exhaust company to fit straight through pipes. Cost about £250, took a day,
