Need A Hand With What Exhaust To Get?

[4doors13secs]

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.

On R33's, was there an option anyway to have a butterfly system (all the wiring diagrams ive seen are on them)? can this be modded to suit newer systems?
