R33 Gtr Question? Power Increase/boost Increase

[R33GOD]

hi guys

just hooked a boost gauge on my car and it runs 10 psi with only a 3 and 1/4 inch catback exhaust. is this normal firstly?

by finishing off the front pipes and a higher flowing cat will it increase my boost. if so, by how much roughly?

And what sort of kw gains are expected just from the front pipe and cat?

thankyou

Anth.

You probably have the boost restrictor in it

See DIY section for details about removing it and so on.

yes i do. i want to keep it in. dont want to run the risk of blowing the stock turbos up.

but what i am asking does the full exhaust bring boost up, if so by how much....

Yeh leave it in is not worth the extra 20-30hp for the chance ya might be looking at a rebuild if one turbo spits its chips, save ya pennys and just upgrade them, with the exhaust from cat bak you shouldnt get any gains on boost but if you do front pipe and dumps you can expect a 1-2 psi rise
