I have the Cat back and front pipe on my car, i'm looking for a dump pipe in the near future..
I'm still with standard cat also.
I've heard that not having a high-flow cat can limit the amount of boost you can run with a bleed valve??
ie. My mate got a turbosmart boost controller on his 180, and they said he needed a high-flo cat to get a full 12psi, as it's peaking at 12, then dropping to 10psi ?
Any truth in this ?
Could explain why my "home-made" jobbie that gave troy 10psi, isn't working on my car (still at 7psi)
