all u can do to reduce it is get a resonator, unfortunately it reduces the loudness factor in of ur exaust in general it does get rid of the aweful resonance, i have a resonator off a V8 commodore, it has 0 restriction and has almost totally eliminated the noise, it pretty much only does it when the car is cold now. On the plus side it gave the care really really deep note.

This noise got me defected yesterday, i knew it would happen, i was surprised i lasted this long with the noise. I might investigate into a full catback system now.

A v8 resonator hey??, might request for that aswell, i am over huge noise, im all for performance now.....as much as my na will provide anyway. Start with cat back, move onto cat, then incomes the extractors.

yep, they reckon they use it on the newer v8 commies and fords, he gave it too me for free cause he felt sorry for charging me for a new cat and it didnt even fix tghe problem, or if they know about it, ask for the resonator they use on twin cam corollas apparently these work even better.

My car does this as well, did it with stock exhaust and still does it with 2.5" cat back exhaust with TRUST stainless steel muffler (no resonators or additional mufflers).

As others have said seems to be worse when the car is cold, pisses me off cause I rev real slow leaving my street and it makes the noise around 2500rpm, sometimes I shift as soon as I hear the noise start cause I think it sounds sh*t.

Only ever does it around 2500rpm-3000rpm never high in the rev range.

Took it to exhaust shop the other day who installed my cat-back but he had NFI what it would be. He got under the car while I revved it but it didnt make the noise (I think it only does it when the car is under load).

It's embarressing when it makes that horrible noise!

Do you think it's worth getting a resonator put in?

I have no idea what this "noise" is, I'm going to try upload a sound file of my gts, tell me if this "noise" is there...

hmmm the file is 40mb lol... How can I make it smaller.. it's a video and soun file.. you don't really need to see the video part tho...

Putting a decent resonator on your system eliminates it completely and as NA_33 said, although it becomes a bit quieter it sounds much deeper. I can relate to what all of you guys are saying, it kicks in around 2500/3000 rpm and makes an awful crackling/vibrating noise. I to was embaressed changing gears b/c the sound was that awful! Trust me, all you need is to put a good resonator in the piping, you'll be thankful.

I know its an old thread but if anyone is reading Id highly suggest a resonator. A single muffer and cat will always sound awful on an NA car, a good muffler with a good quality resonator will really bring out the awesome note with out the horrible raspy/cackly noise.

      After market rear camber arm adjustment

      By Jarsky · Posted

      This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Its a well known brand in New Zealand; its a rebrand of the Rhino RAV3.  I don't know what the wiring difference *is* between the rev.1 (installed about 15 years ago) and rev.2; but as you say I would think its reasonable that it uses the same immobiliser relay circuits. I had a look but couldnt see a similar harness; but didnt move things around since I didnt want to mess with it   It was one of AVS well known Authorised Installers; I spoke to AVS themselves about it but theyre unsure hence seeking advice more so from the skyline community who are more familiar with the actual car and its wiring. Im in Auckland; but the installer is on the other side of the city so hes very reluctant to come back to even look at it to confirm something isnt connected into the wrong wire.  I dont want to drop the name since they *did* do a really good job for the most part. Everything is very tidy and he fully replaced all the alarm wiring, all the sensors, the wiring to the door motors, installed a switch which was never installed in the first place...really happy with the alarm install itself..just not this one issue. We all make mistakes, if it is the alarm, I just want my fuel pump getting proper switched, fused, power as it was; without having to shell out for an auto electrician to switch a wire and tell me it was the alarm.

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
