Hey i just test drived an n/a skyline, and it has a 2.5 cannon muffler (not straight through) and it was really loud. liek my ear was going funny, is it common, uncommon, or a fault, also, if i were to buy it, wat muffler would i buy to quiet it down a tad,

is it common for rb's to be that loud?

Thanks Nick

Hey mate, Yeah depending on what style of cannon it is it can make things quite lould.. I had a seca corolla with a 2.5" cat back system and a cannon from REPCO and it was rated at 146db at 5-6000rpm.. was reduculious lol so got it taken off in the end..

and so what i reccomend if it dosnt have a aftermarket exhaust just replace to a stock barrel and tip again put on..

If it is an aftermark one just replace the cannon part if u do buy the car..

Hey man did you happen to notice what brand exhaust it was?

Did it have a silencer put in?

If you know what brand it is you might be able to get a silencer from the company, my exhaust a kakimoto racing one has a silencer available.

if not you can always go to a few exhasut shops, they can probably set you up with one..

Thats if you didnt want to go through the new exhaust hassle

My exhaust without the silencer is insanely loud, the ppl at woolongong hated me on the cruise yesterday

p.s. N/A skylines are always louder, turbos seem to quiet them down a bit

nah, didnt catch it, i guess its somthing i should have been asking, lol. so you rekon i can pic up a silencer, man it was so loud... my old mans like you would get so annoyed at it after an hour, but yeh, i guess i can just replace the muffler later on if theres no silencer :angry: . Thanks mate

yea the turbine in a turbo muffles the exhaust and makes it a tad quieter.

you can always get a center muffler or a new one welded on for like $200 and it'll be a lot quieter

ive got a standard exhaust with hot dog on my car ending in a DRIFT brand cannon and its pretty quiet most of the time.

Cool thanks dan, so many ways to quiet it down :wave:

the ones you see on cannons just makes the outlet hole a lot smaller so it restricts the exhaust flow a bit to make it quieter. my cannon came with one but it looks pretty gay when its on lol.

Hmm, well the 33 i looked at was pretty much undrivable my ear went distorted lol, i just want a nice purrr, :D

Before you do go out and buy anything have a look and see if all sections of the exhaust are boltd up tightly with good gaskets, some places may need goo, new gaskets or several gaskets.

Will, do....but an easy fix if that seems to be the problem?

i have the same problem

bought a r34 n/a

its a 3inch kakimoto...

:ermm: what are the best ways of reducing the sound

A 3" on an na is way over exhausted. 3" is best suited for a turbo, most likely your exhaust is for a turbo and was brought of ebay or something.

your best bet is to change it to a 2 1/2" (understandably its not the cheapest option) ether that or do to your local exhaust place and get another muffler put in.

another note, im fairly sure you dont have to get the same brand name silencer so long as you get the right size for your tip (i have seen them for sale at autobarn) then you just have to knock it in and drill a small hole in the very end of you cannon and wack a nut and botl through to hold it in. (dont asume just because its a tight fit it will stay in without a bolt, it will fall out one day)

panda.

ive always had 3inch systems on my falcons, and wen i asked about one for my n/a R33, the exhaust guy refussed to do it. he sed that is the biggest over kill to a non turbo 2.5.

2 1/2 inch is ideal for 2.5 DE's. im getttin mine on tomorrow along with turbo tec trackies and a "metal cat". and no cannon, tryin to be different.

ur cannon may have also had baffles taken out for a louder tone, all my mates do it to their exhausts, its shockin

    • Had a chat to Tony Mamo - he advised that looking at the graph's shape (regardless of number translation) it shouldn't be levelling off like that up top. He said it looks like the car is running a restrictor plate or something of that nature. Luckily the last dyno pull on E85 was saved to the PC - So I did a quick trace of Barometric KPA vs Intake manifold pressure, and lo and behold I see a copy of the 'waves' I was seeing on the dyno: I'm not entirely sure how to go about addressing this. It may be worth sacrificing IAT to run a more direct intake for the motor. Though packaging this could be flat out impossible given the constraints of the car. I should have removed the intake pipe to see if this made a difference but looking at this graph I now have something to potentially test in the future and think about. This one is from an old track day log in the OLD setup going through gears on track.
    • Oh, I forgot too, all the multimedia stuff captured and sold through things like people playing Pokemon Go. Pokemon Go specifically, can actually be traced all the way back to a CIA investment company too. So yep, they're watching everything. Not to mention the new stuff where they've worked out how to use WiFi signals to be able to map occupants inside of a building. That one would be something that I see being more used in public/government buildings, as you need to understand the signals when the room has no one in it first. It's not as easy as Hollywood would like you to think it is.
    • Followed ☺️ Assuming those are NEO rods, then at least 400kW all day.
    • Lets keep this going , Spotted this very stock V35 in Penrith and also saw a nice R32 FLY past me on Castlereagh rd , sounded really good.
    • Great work! Give it a clean up with some Emery paper, and I'd run a thread die over the threads too to clean them up. It will make reinstall much easier, and also life easier for the next time it needs to come out.
