Like any exhaust, how loud it is depends on your tune. A PEII on my GTST with stock ECU was quieter than the stock exhaust (which was really weird), but once I threw on a PFC, raised the boost, it got a nice rumble to it. Doesn't drone though.

1) Fit an Apexi (or variant) exhaust control valve for $250 fitted, which would almost guarantee a quieter exhaust but i'd still have to manually play with the valve everytime I drive due to loss of power when the valve is closed up.

i have never heard of one of these but always thought theyd be a good idea, didnt think any companies had actually made one. where can i get one from??

I fitted a PEII to my r32 gtr last week... Its barely louder than the stock exhaust, but also sounds nice. I did 600km on the freeway over christmas in it, and it does not drone one bit.

Does the PEII flow well? Would you expect that there would be a power drop over say, an Apexi N1 or similar?

Cheers...

i went from stock to 3" straight through and without making it loud at all..

based on my experiences, i think there are 2 problems with why exhausts are too loud:

1) people but 10-year-old brand name aftermarket exhausts and the muffler / resonator are as good as a straight through pipe. GET NEW MUFFLERS, or simply get a custom-made exhaust for cheaper that automatically comes with new items

2) people don't run a resonator. I got the largest resonator fitted that could be ordered and the flow is still great but the drone is virtually non-existant.

cheers,

Warren

my r32 gtr has stainless 3" front pipes and 3" cat and stainless mandrel bent rear section with straight through muffler which i built myself (didnt build muffler obviously).

i dont find it noisy and i love the vicous hard edge note when the motor hits boost and i am seriously considering removing the muffler and replacing with straight piping to increase the noise. it doesnt drone at all.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
