R33 Gts-t Std Exhaust

[Noel]

3 Things...

As the topic says what size is the std exhaust on a R33 GTS-T?

Also if i upgrade IC & add boost (10psi) i know it is beneficial but is it NECCESSARY to increase exhaust size???

Lastly what do you guys think of just getting a 3" from turbo back with a split dump pipe & high flow cat but leaving cat back exhaust as std?

I dont want people blasting me saying im stupid etc especially since i have not done any of the above but i would like to hear your informative opinions & reasons why & why not.

Thanks

Hi Noel, Sort out your battery issue?

Std Exhaust is like 2.25" or 2.5"? Around there I think.

Id say get a whole new exhaust from turbo back? Depends how much ya wanna mod our car I guess. Its a endless money pit :

Hi Noel, Sort out your battery issue?

yea thanks I got myself a 450CCA battery (MF55B24R) from Supercharge Batteries http://www.supercharge.com.au/ in Arndell Park & problem is now solved ;-)

yea but is it neccessary to do it (exhaust) if i up the boost to 10psi & get get a better IC? or is it just better to do it?

if its gonna cause damage to my car cause i have a std exhaust i wont boost it all all but if its gonna be fine and just wont go as well as it could, i'll do it & leave exhaust (for now) especially since i love it being quiet as a mouse atm with the std exhaust.

Thanks

It wont be that bad but a turbo back exhaust will give you a stronger pull at the high RPM ranges and taking more advantage of your increased boost.

there is no point upping the boost on a stock exhaust. it won't be able to flow enough air to make it worthwhile. you need to be able to let the air out properly before you start pumping more in. also it will hold more heat in.

makes sense...

what about just getting 3" turbo back/split-dump & cat vs just getting 3" cat back exhaust?

I know both is the ideal but if i were to get one or the other which would be more beneficial?

Thanks guys..i am just interested on peoples opinions/feedback on these ideas?

Cheers

a full turbo back is going to give a better power increase, as well as get cool the turbo slightly (the hot gases can flow away from the turbo faster). generally if you get it in 1 hit (like a full x-force turbo back system) it works out a bit cheaper than buying a cat back, cat and front pipe seperately. just depends on what you want. if you were going to just get a cat back i'd get the cat at the same time.

Yeah id deffinately get the hole system it will help make the whole set up much more efficient. I also found my boost went up a couple psi by having the split dump and turbo back exhaust due to the much better flow.
