hello SAUers,

i have a Fujistubo Super-Ti Titanium 3.5 inch catback exhaust on my R33 GTR, as you will all know they are known for being quiet, i mean the car is loud past 3500 rpm buts its really quiet on idle, i was happy with it but sometimes i do feel like having a louder exhaust that is a bit louder when on idle as well, im currently geting work done on the car and also put in a high flow cat and JJR Front Pipes, i was told this would alongside increasing flow also give the car a deeper note, but i am wondering whether its worth it to get the resonator cut out and put in a straight pipe, would this help with flow as well or will is just increase the exhaust volume?

its a tough decision as currently cops never hassle me as the exhaust is under the legal limit and quiet on idle when i get pulled over, is it worth getting this done and have the extra attention from police and possible defects ?

Any help appreciated

Cheers

Adam

Leave it alone - good front pipes and a high flow cat will improve flow rates and deepen the exhaust note at idle - it did for me.

When I warm my GTR up it is reasonably quiet up close but the deep note resonates that much that it makes my car port vibrate and rumbles up and down the street just to upset the neighbours. Once warm it is nice and quiet down low to keep the cops happy but as soon as you open it up it has a strong note.

The other thing that the resonator does is to stop the drone when you are cruising along - the drone is something that gives me the shits very quickly.

Give it a try and see if you like it - you can always change the resonator some time in the future if you want to.

I run HKS Priest exhausts on my R33's. These have a front muffler, a resonator and then the rear muffler. The resonator looks like a hot dog muffler and just takes the growl out of the note.

My son has a Trust exhaust with just a front and rear mufflers and it is quite a bit louder.

    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
    • Yes then it will turn on but I want the car features to work  
    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
