if you are after a quieter exhaust, get an oval muffler not a cannon. or if you must have a nice ricey cannon get one with a big body, and small hole. this maximises the amount of noise that can be reduced, but also reduces air flow.

Hey mate,

well if your after quiet then a cannon isnt the way to go....

i will attach a pic of mine dunno the brand, but its quiet as on idle sounds deep the way an rb should be, but produces good power, on boost its not gonna matter what you get its goin to be noisy. i hope this helps you in some way.

exhausts sound different on different cars..

if you're after a quiet exhaust then basically you want to look as the muffler and resonator

muffler: the biggest body you can get with the smallest inlet/outlet that you need to match the rest of the system

resonator: as above, but you want to get a big one again.. don't forget the resonator or your eardrums will cross you off their cristmas card list

sinista , i like the look of yours and how much are we talking when boost kicks in ? as far as noise?

it wouldnt be as loud as a cannon you see on most of those little civics n shit that sound so loud n zippy all throughout gear changes ,

but yeah where do you recon i could pick up a muffler like yours ,

Hey mate,

well its not really really loud like a cannon but makes a good sound, look at it this way i wouldnt get pulled up for it bein too loud but it certainly doesnt dull power or sound like s*#t lol. and it doesnt sound zippy at all, never heard an rb that has really. best place maybe try a muffler shop, or keep your eye out on here for one, i bought mine off here from a member.

would a cannon sound quieter on a skyline compared to a non turboed car?

anyway im thinking of going an checking one of those that you have , but do you have an sort of idea what that is called ,

also how much do you recon im looking at getting a full exhaust? , would it be beneficial getting a bigger dump pipe?

cannons are pretty loud there not whiney like lancers etc there loud and fierce. full exhaust depends on what you buy and where from really, and yeh it would be benificial getting a bigger dump, but i mean if you can only afford a cat back at the moment then do that. i have no idae what my muffler is called, most muffler shops have a catalogue book, also if you explain your requirements then they may be able to help you.

Ive got a 3" system with high flow cat and a $100 cheapo cannon. It sounds really nice at idle and full load, has that fantastic skylne roar. It is quite loud though, definately not legal but it doesnt drone like those commodores that would give you a headache driving everyday either.

Id recommend if you want quiet and decent flow 3" with a big resonator and as said above, the biggest bodied muffler you can find, a 2.5" outlet wouldnt affect flow too badly. Something like sinistagtst has would be perfect, they look much nicer then a cannon as well.

$900 for a new cat back and you reckon its too expensive

I swear, some people shouldnt own nice cars - dont ruin your car by putting cheap crap on it

If you cannot afford new, there are some excellent 2nd had systems around, quality systems that work and sound great.

Alot of people will argue, but I dont give a shit, I see so many cars nowadays with cheapo exhausts/wheels/etc - and it turns what could be a nice car into a bucket of crap

If you cant afford to do mods well, dont do em at all - otherwise you will just de-value your car.

If you want a quiet exhaust (well relatively) the Nismo 80mm with a centre muffler, and oval resonator on the back is quiet, not sure what model sorry.

Otherwise, find a nice flowing exhaust, and add resonators until you get the sound you want.

But please, dont fark up a good car by putting crap on it. (and cheap stuff off e-bay is 99% garbage)

the first ebay exhaust has no centre muffler so it will be louder than most others.

the second ebay exhaust you posted is an x-force, and it is turbo back. it is a good price too. it won't be legal (but then most skyline exhausts aren't) noise wise, but will sound good. i have the 3.5" version and it sounds cool.

as for the muffler, there are a few choices in oval mufflers. lukey make a 3" 'megaflow' which is a centre-off centre muffler so it flows well as well as taking noise out, as well as a few others. also x-force do some oval mufflers as well.

otherwise try to get a jasma muffler. the best of the jasma mufflers split into 2 inside the muffler then join back up just before the tip. the sound very nice, and are very quiet. i've been in 2 r33's with them and they are extremely quiet, but growl nicely. they are quieter than the jasma muffler that is just a straight through oval.

My muffler is the same that you are describing here, splits in two and rejoins as i said i wouldnt get pulled up for noise but it sounds nice as.

a cannon would be heaps louder on a lancer than a skyline, my civic has a 2" sports exhaust no cannon and is bloody loud, where as my skyline on idle has a nice note, and only untill ur floggin it it starts to roar, but its hard to tell coz the screamer pipe is alot louder

but yeh cannons on N/A cars are wrong IMO

I was quoted around 1200 for a full stianless x force fitted like that ebay one (for a stock R33). Sounds like a good price? Does anyone know if this system is droney at all?

Im not really worried about it being loud, but cant stand that drone that some cars have! and i havent really heard many liner exhuasts to compare to.

...What turbo back system do you guys reccomend for a good deep throaty sound, around or a little above the legal limit?

Any good exhaust places in Sydney?

Any exhaust place can knock up a 3inch exhaust and tailor it to how loud u want it

I just got mine done (cat back) for $400 with an oval muffler with twin tips - its loud, but if u want it quieter they can put a resonator on it to quieten it down

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      Mistakes were made, my R34 Story

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Infiniti Q60 Navigation Update

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
