Exhaust ideas...
I am aware that this has been done to death but I've got yet another exhaust question (in-between using the search function!)
I was running long-tube headers (don't know the brand - bought with them in situ), stainless steel system with cats (possibly Borla) and Borla axle-backs (I think that they're Borla S). Now Iwas very disappointed with the noise levels which were waaaay too quiet up until c.3500+ rpm whereupon it was quite pleasant but still too civil  . Whilst the car was in the garage for some paint I had the axle-backs removed and  the right volume was to be had - however, obviously, there is a little trade off... on a light throttle it sounds really good and not too loud, stand on it and it is quite raucous really give it some beans and it sounds like WWIII approaching  . Now whilst I am happy with the volume levels (maybe a little quieter wouldn't be a bad thing  ) it does sound a little 'rough' or 'uncultured' for want of a better expression and the drone at 40ish mph is mother  .Given that I'm not really too worried about the volume at high revs (don't visit 4k and over that often to be an issue) what sort of axle-back could give me what I want: 'rough' edges to the sound 'smoothed off' and drone ameliorated (if not gone completely) 1. Would a generic silencer manage to take off the excess raspyness/roughness? 2. would a J-pipe without a silencer do anything (except with help the drone) 3. I'm not going with electric cut-outs (no weeds etc) as buy the time they're over here and fitted it's waaaay to expensive and our annual roadworthyness tests can be a little 'fussy' regarding these 4. car is a 2013 SS auto (cylinder deactivation has been shut off)

Why did you decide to go with the Borla S-Type instead of the ATAK?
