What Have You Done To Your Stagea Lately?

[Sunkist]

Aaron, don't quote your exhaust as a "JASMA cat back system" as those who don't know it is a Kakimoto R may try searching for a "Jazma" brand exhaust.

If a cat-back has JASMA accreditation in Japan, it just means that when held at 3000rpm, the exhaust sound is under 95dB.

Yeah, it is about the same volume as a Fujitsubo Legalis (~90dB) and a touch louder than my Nismo

If you really want quiet, you just cannot beat a Blitz NUR for NM35's.

sorry sir. please dont beat me with your bohemath like hands

I find it makes a fair difference on mine, dare I ask are you sure you opened it up the whole way? bigkevracer was in my car for half the SA Stagea cruise on the weekend and thought the exhaust sounded like it almost had a slight leak at 2-2.5k RPM when on the highway cruising..I dropped it into silent and I think the reaction was basically a 'Well, yep. That switch is definitely working, and you definitely dont have a leak'. Stealth mode ftw

sorry mate i should mention i only have the rear muffler on the car. the mid one is still the big stock one. hence why it didnt make a HUGE difference. however it has a nice note to it! and a nice rumble at idle

stephen was running his the entire time with the valve closed, i never heard it with the valve open!

pipster, keeping the car quiet is exactly what i want it for. i dont give a crap about performance. thats what opening it again does

I can vouch for that. Totally astounded that an exhaust I could see through was as quiet as stock. It is louder at the back when you get up it, which is nice, & deeper at idle, which is also nice , but mainly I noticed that the induction noise dropped way down (not sure of science behind this) so overall NVA is reduced when driving normally. There's no doubt that Japanese exhaust designers/manufacturers know their craft.

I have before & after videos which I will post on the exhasut thread soon for those interested.

yes please Leon!!

also mention if you have a dump/front pipe too with the videos

yeh i noticed my exhaust became a little louder and "tinny"(if that describes it) when i put on scotts Dump.

i'de like to see a video tooo leon!

[Commsman]

Yep, will get onto it. Might get my daughter to compile & subtitle them since that's not really my thing. I should actually do one more so that I have:

a) totally stock - with the centre muffler that's the size of Iain's villa, lol

b) with Scotty's dump pipe and Blitz cat back, but still with 2.5" front pipe & cat

c) as it is now with 3" front pipe & hi-flow cat installed (I need to video this one still).

I even got the measuring tape out so that each video was recorded at 50cm from tip. Otherwise it's impossible to compare sound levels from one to the others. Mmm, reading this back makes me seem a bit OCD or autistic .

i might follow in your OCD Path and do it at 50CM away lol

Yeah buddy, do that. I'd love to hear the difference. Hold it just off to the passenger side. My son held it almost straight on the first time & the lens fogged up with the moisture .

Although, different cameras will have different microphones so it won't be a really accurate comparison.

my villa is pretty big dude, and i have double garage. so i dont know how big your muffler is

[Sunkist]

a villa is a villa..

do you have a teepee too?

[zei20l]

negative, but we are soon to have a pergola out the back...... might get some tomatoes growing on it. being that im in tuscony and all

[Commsman]

No offence . I am just remembering you saying recently that the centre muffler on your car (same as mine) was "as big as your house". Now that today we have established you live in a villa, I just thought I'd be more accurate. Again, part of my autism, lol

[Sunkist]

Let's clear it up. Iain lives in a massive villa and is soon building a teepee so he can grow crops. He's starting a new age

[zei20l]

im playing civilization, but in real life!

im in the bronze age right now, we are working on mathematics so i can actually build something nice to live in

[Sunkist]

Like a villa?

[zei20l]

now you get it!

We have those down here, they are commission homes.
