  1. hi all

    im thinking of decating my car but its got a middle box chop and backbox chop too, im just wondering if i decat it will it lose too much back pressure? i know it will be abit on the loud side too but my main concern is the back pressure.
    cheers
     
  2. I always thought back pressure didn't matter with a turbo'd car?
     
  3. i dont know ya see its my first turbo'd car so im new to all this haha
     
  4. It'll sound epic.. But if you track it you might be near the noise limit on some tracks
     
  5. oh good was unsure what it would sound like, n the track thing will be fine not tracking it for a while untill i get to know the car abit better
     
  6. I wanna hear it if you do...I had a mini turbo with no boxes and that sounded sublime.
     
  7. i will get a video up once its done, havent got the decat yet but hopefully will in the coming month or so :wink:
     
  8. that will be mental loud! I lve heard a meg with just a mid box chop and that was loud!
     
  9. Turbos dont need or want backpressure. Get rid of the gas the most efficient quickest way you can.

    Seriously I would advise running at least one box.
     
  10. As Andy said....you look at group b rally cars, turbo and a bit of pipe to get fumes outta vehicle. In a road car however....
     
  11. I had that and tbh it sounded awful so bought a full miltec turbo back. Was far to loud and just didn't sound nice mate
     
  12. Right then lads I'll get a decat but I'll fit a back box too or a full system of some sort cos I don't want it chavy loud had that with my fiesta I had before. Cheers for the help tho people :smile:
