no your all wrong, its the turbo xs loudest ion the world hrfl

blitz imp reza

Yep turbo XS is claimed to be the loudest, but the blitz and HKS can be pretty loud with changable inserts. There is also the twin trumpet MRT and you will be intersted in the turbosmart supersonic at the bottom of the page. Take a look here.

Bit of a shame it makes your engine run worse then?

BTW, you're all wrong. The loudest Impreza dumpvalve available is the standard Subaru one. Its design is so high tech that the majority of the noise is ultrasonic, and thus beyond the realms of human hearing. In other words, your granny won't get scared to death, but your dog (who's probably called Scooby anyway) will hate you.

Anyway, this isn't a drivetrain question, it's 100% Max Power and so should be either in Styling or Muppet Show...
