Kakimoto is quiet. There was one on the FS within the last couple of weeks. I'd buy that if I still had a car - my favourite muffler for a road car.

Fujitsubo is also known for being quiet.

You might wanna put your setup now - there might be a cheaper way.. i.e. if you have a hot dog and cannon then the easiest way to make it quiet would be putting in a mid muffler, it would be cheaper and might sound good.

Good luck.

Go to your local decent exhaust shop and ask them to replace your rear muffler with a Magnaflow oval muffler and a mid oval muffler also. The noise is made by the internal design of your cannon/mufflers.

I changed from a jap exhaust to a custom cat-back and the difference in noise was astonishing, no more drone, popping or headaches just a constant quiet RB26.

I have a 5Zigen oval muffler & literally cannot hear it over the tyre noise. Dunno is you want it THAT quiet, however.

By the way it has a JASMA plate on it starting with 92-. not sure if the 92 in some way refer to the dBA rating.

I had a 3 inch Nismo cat back with the middle 'muffler' and oval rear muffler and 4" tip, picked up 2nd hand for $350 from an importer.

It was as quiet as, prob a little too quiet - i.e. did a 5000 rpm launch with cops on the other side of a van beside me and when they pulled me over they didn't mention one thing about the exhaust, only how fast I took off. No tyre squealing tho(32-GTS4)so that probably disguised the speed of the takeoff a little as well as the quiet exhaust .

Didn't even get a ticket so I am glad the exhaust was quiet.

I just fitted an HKS Silent Hi Power cat back, i was dubious about the silent part as i could see straight thru it and my daughter could fit her whole arm inside it. once fitted i was impressed, it achieved all its goals.

At idle it still sounds a little herby (i have cams), but on acceleration and deceleration it silences quite well, with little to no restrictions.

overall - impressed.

Most aftermarket systems are over the 90DB legal limit.I have a fujitsubo system.Which is really quiet.

However i managed to get defected for it.It was 94.6DB.The standard system i have on it now is 88.5DB.

The fujitsubo Legalis R system is 89DB at 4500RPM.That would be the system id recommend.

      I picked up my block and head last week and have been slowly assembling it since then. Pictures I took earlier this week. The rest of the auxiliaries are on now. I just have my intake manifold runners to tap for my WMI direct port setup before putting it back on. I should hopefully have the motor back in by this weekend.

      I couldn't agree more. As an owner of a built high HP skyline, I'd be a hypocrite to not buy a Hummer for the reasons you listed though haha.

      Stagea boot lid probs

      By soviet_merlin · Posted

      Is this the one? https://jpjdm.com/shop/index.php?id_product=2192&rewrite=nissan-stagea-c34-rear-boot-actuator-assembly-90550-0v000 Might be worth having a look at yahoo japan as well. Though it seems a bit odd. If the motor works itself, other than being noisy, then wouldn't it be more likely that it's an electrical issue somewhere else? And it being noisy does not seem as surprising if it has been chugging away for months

      Stagea boot lid probs

      By BCs300z · Posted

      I know this thread is quite old, but I found it, it helped me, but I also wanted to add my experience and troubleshooting finds to the chat for others. I have not been able to open the rear hatch of my 97 Stagea for several months. Figured it had just really sealed itself up over the winter and I would just get to it eventually. Well that day was yesterday. Some time ago, I noticed my battery was going flat all the time. It was frustrating. Then one quiet night in the garage, I could hear and ever so slight humming / grinding noise coming from the back of the car. It was like a really quiet popping sound or something like sand in a very low speed blender. I took off the panels in the back and noticed the noise coming from the auto close motor, so I unplugged it and the noise stopped. And the auto close was disabled. Well, fast forward to yesterday, I tried all the tricks with power and fuse and lock and unlock and I still could open the damn hatch. So I took off the panels from the inside and found the auto lock had engaged and was stuck in close position. When plugging and unplugging the fuse, I could hear the relay clicking. So I plugged the autoclose motor back in, and the damn thing let go. And immediately started making that grinding sound again. This time, instead of just unplugging the motor, I pulled the fuse, thus depowering the relay entirely. I don't have the autoclose feature now, but at least I can open the boot and not have my battery being sucked dead all the time. Not sure what caused the motor to latch when it was unplugged from the system, but I am pretty sure it won't cause any more problems now.  If anyone has a lead on a new motor, please let me know. It's a cool feature that I would like to get back.  Hope this helps.
