hey all, i bought my R33 gtst 4 door about 6 months ago and im about to start upgrading it slowly and i was just wondering what exhaust side i should go for? some people have said 3 inch for better perfomance but i dont want it to sound too loud as i like hearing the turbo spool (i no it sounds silly but hear me out lol) and for that some people have said just go 2 and a half as it is stil good for perfomance and not as loud?...

im sort of more lookin for other skyline drivers opinions on it...

thanks..

In my opinion its a waste of money upgrading if your only going to go 2.5"

go 3 inch but just make sure there are adequate mufflers in the system. The reason why probably most peoples exhausts are stupidly loud on the street is they only have a resonator/hotdog in the middle instead of an actual muffler (or skipped a central muffler altogether). Also don't make your rear muffler isn't the size of a gas bottle and you shouldn't get any drone. May even consider going twin outlets to keep the exit pipe a smaller size (but at the end of the day its still the same open area) this should help keep the note higher.

I can personally recommend the trust power extreme 2 for being relatively quiet. But i certainly know HKS market a series that claim to be relatively low SPL.

I Have a Trust Power Extreme 2 Stainless cat back system and it awesome. I have been pulled over into defect bays and passed 3 times now!!!!!!!! Mind you I was still packing the pants full of goo....

I also have a just jap dump pipe and a high flow cat.... Looks sweet as well... None of the fake titanium tip crap

Go 3 inch (that's the recommended size for the motor)

Make sure you get it turbo back.

Don't forget high flow cat convertor. This is pretty essential if you want to remove restrictions.

I can understand the noise factor. I don't like driving around making a racket and getting seen by cops, or even just being uncomfortable in my daily driver. Look around for 'quieter' systems, or get a silencer.

yeah definately go the 3".

I think you can still get exhaust butterfly systems like the Apexi that used to be on the market. I've been looking for one for my car.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
