Quick question on changing a not too loud exhaust

I just brought a r33 T for a month, start considering to change the exhaust since its too loud for me (arr.. for my gf actually....)

im a newbie anyway :) so please give me some advice on this, how much does it cost in Perth if i want it quiet and also good performance (reduce sound and not restrict)

already did some search on this site but found thats not a good idea to put a silencer

(the car is pretty stock, no mod on engine/turbo)

Thanks

My gtr got quieter once i removed the muffler 3 1/2 inch straight through to resonator now and it is one of the quietest Lines on the road

she will get use to the noise, its prob not even that loud haha, wait till you hear my 180sx, rb20 no cat 3inch all the way then twin 2.5 inch tips.

also do you know what exhaust system you have atm, like is it straight 3inch from cat or does it have a muffler also. and how loud we are talking about here if you can explain.

but if you really have to. just do what bubba said to do, should cost a few hundred, depending if you have stainless or mild steel. not sure on what brand but i am sure the exhaust place should help you out.

there is a cheaper way but it looks funny, is putting a silencer on the tip of the cannon (if you have one)

u mean u take off the whole thing from the muffler to the resonator on mid pipe? it ll looks missing sth at the back

auctually i just want to know is that true "for t sport car, the quieter the exhaust the larger the back pressure, the greater the damage to the engine"?

i had the muffler cut out and a piece of 3 1/2 inch exhaust pipe welded in its place

get a couple hot dog mufflers welded into your exsisting system, it'l drop down the droan of the note without creating a huge restriction and in turn quiet down the rawr comming out of the end. or if you really want to quiet it down get a massive muffler put in the middle.

      Boost level and torque curve

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.

      so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?

      That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
