on my R32, i have a Flying Performance (www.flyn.com.au) 3" Dump Pipe/Front Pipe combo, a 3" highflow cat, and a 3" kakimoto catback exhaust... i think it reads around 87 - 88 decibels

Is the kaki cat back single muffler or does it have 2?

hmmmmm if urs is 104 i wonder what mine would be :)

Ni, remember my GTSt had the trust ay 109dB... the GTR is running the same exhaust now, and this is definitely louder - and it has a 'silencer' of sorts...

I reckon you'd pip the 115dB mark, just by hearing it at track day (that's about 4 times as loud as mine)

700 fine

OMFG shit i better get my one Fitted Mine is Over not sure how much but i have the THing in the tip and its still shit Loud

I asked them to Make the system Under the limit by it is so ****en Loud it hurts my ears without the silencer in it over 3500 rpm's y is it so loud its a NA Sr20de Auto

Only a Cat back System thats 2.5" with a canon on the end no mufflers in the systems canon is 2.5" inlet and 6" to 4" tip

yeah all the tests were done accurately... when i get some time im going to take the ceffy down and get a reading at 3200rpm and 5200rpm :cheers:

the soarer on 106 @3200rpm was funny cause its loudest between 4000rpm and 6000rpm

    • I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps
    • Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks
    • small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.  
    • I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛
    • Nah, not really responsible for that little fiasco, but I'm still pissed at myself for writing off my 86, or when I reversed my VX into a pole just before selling it, but, meh, 5hit happens to stuff, all it takes is a slight distraction, and life is full of distractions, and "dooh" moments
