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.

    • 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?
    • 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.
