Decat mani + Exhaust question
Bit of a random/specific question. I'm currently planning to get a decat mani (Tegiwa or Japspeed) along with a FlashPro. I wanted to keep the stock exhaust as I've read in many different threads that there is a motorway drone with a decat mani + any other exhaust system.
Will my gains be restricted this way due to the oem exhaust?
Another option is buying something like a Milltek with a Cat welded in, apparently there is no drone but obviously the cat will affect some of the lower range responsiveness etc.
Which one would be a better trade off?
Will I see gains with Milltek + CAT vs just decat mani with stock exhaust?
