Im looking for an exhaust with decent hp gains, a nice idle tone, and a aggresive acceleration tone. I have kinda narrowed down to Borla or Nismo based on weight, hp, and dp at idle and cruising. Is there any other exhaust that out shines nismo or borla in these categories for the same price? Im leaning toward single simply because FI isnt going to happen but NOS maybe.
