What Is The Quitest Sport Muffler


Recommended Posts

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 still have Garrett parts to build GTX2860 if interested. 
    • I reckon coilpacks too. Mine went at exactly 100,000kms
    • In the process of riding up my car lol, am trying to get a decent looking oil cap. Some say they are fine to fit all RBs or even all Nissan, others like a stock GTR oil cap say rb20/25/26 but they won't fit a neo rb25. Is this due to the stock plastic engine cover or is there something else different?
    • Well Coolant pressure increased significantly under + boost.  Enough to bypass rad cap Coolant pressure normal under low load conditions and no overheating. Head off and you can see where it was bypassing the cylinder ring to coolant chamber on both head and gasket. Head cracked tested and serviced, all good. Block was only visually inspected, so please god ...  let that be ok   You could argue that is a Head gasket failure but it was still very much a complete unbroken gasket. So suggests some stretch on the factory head bolts. I know others that have had the same as above and not even taken the head off, just put in studs and  continued on for years.  
    • Just jumping into this one, someone's decided to try get into my 34 by bending that top door window trim back.  Anyone know how to remove these? Going to try and bend it back properly and sikaflex it... Cheers
