HKS Dump Pipes on Factory GTR Terbs?

[Gav]

I've picked up some HKS dump pipes (the s/steel split adaptors that bolt onto the turbos).

Given the amount of work to fit these suckers is there much to be gained fitting onto the std GTR turbos?

I've already got an HKS Hiper zaust and will fit the HKS engine pipe at the same time.

Im not sure how much gain you get but if you decide not to put it on I'll buy them off you cos its the only bit of my exhaust left to do

From what I've read its well worth it. I'm trying to do the same thing.Do you mind me asking how much you paid?

[Gav]

The dump pipes were $600 used.

I've seen them advertised for cheaper - but like everything it's all timing.

Hi gav, generally worth 15 rwkw, unles the engine pipe or cat aren't up to it.

unles the engine pipe or cat aren't up to it.

Does a hi-flow cat make that much difference?

I just fitted Nismo Weldina front pipes today to the GTR and I haven't felt a HUGE difference...

I've noticed a difference between a normal cat and hi-flow. Now I have no-cat, and that's only made a small difference, but necessary for my rotational idle.

Front pipes should make a difference, more to torque than top end power.

BTW - where can I gat the steel gaskets (the special shaped ones that separate the wastegate from the exhaust turbine) from?

Gav,

I think Adam32 still has some left over from when he did his. Give him a call.
