Hi can some one out there advise on either HPX, cats back exhaust , or Herrods? i have listened to Herrods & it didnt sound all that great. KW. wise about 12- 15 kw Herrods, as opposed to 10kw increase, for the HPX. system. but have not heard the HPX system....? this is on the BA 260kw ute
There is another choice, contact Aussie Car Enhancments in Melboure. They also have a great system. It is fitted to my XR8 Ute. Not sure what power gains yet, but i will have Dyno runs finished on friday. Will keep you posted.
