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

    • Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!
    • Welcome Alice......hope you have a bit more luck from here on! What was done in the build?  
    • Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!
    • Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!
    • I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
