Exhaust Question Sizes Etc For 32 Gtr

[Angus Smart]

As i have the trust front/dump pipe, which i think is around 80cm after the merge tho i will have to check as i modified mine..

if i go a 90mm "catback" will i get moar power, or should i just stick with 80mm as it will be even all the way through.

im looking at the trust ti-r catback or similar..

Cheers

Hi Angus,

I would go with a 90mm cat back, especially if you are planning in the future to extract some high HP from your RB26DETT....

The exhaust is only as good as its smallest section.

If the merge goes down to the 80mm (i have the same setup, although about to change it lol) then go the rest of the way like that.

You can move the flange further up the taper a little you can almost get it to 3.5" (almost 90mm)

Yeah i'm starting to think i've already done that we extended the merge section to meet the rest of the exhaust (no meow), as i bought trust pipes from a r34 which needed to be a little modified as they didnt fit 100%

i shall mesure it tonite and go from there. tho i think it will be 90mm.

if all goes to plan, running engine at 1.6 bar hopefully around 350kw if not a little more. so a 90 might be a little better.

Yeerrp shes 90mm now, so a 90 exhaust it will be,

greddy ti-r is looking rather sweet right about now!
