Hi,

My mechanic has offered to install a second hand R33 exhaust onto my auto R33. They were stripped from some cars imported from japan i think, probably to get them complied here.

Anyway, I just wanted to ask advice if it is worth taking him up on his offer. I've got friends who say a monster exhaust would sound crap on an auto, and other concern is noise. Don't want to be attracting cops and waking parents/neighbours when i pullup out the front at 1am+.

Is there a practical limit to size. What my mechanic gives me would be pot luck, they are just gathering dust in storage. I think they are around 3inch (tip?) from cat back. Like i said, covered in dust, but bolt on from japanese R33.

Im not a big fan of drone, and he said you'd get sick of the noise in about 10mins. Im just after some feedback from the engine over 3,000rpm. Not concerned so much with HP gained (i dont think it is best return on investment). I only ever do redlight->green sprints.

Planning to keep my license, and take it on a track for kicks. Am i better off just getting a new tip ?

The rest of the car is stock and ive got some cash to burn (i convince myself, until i see next visa bill =p)

regards,

hb/

Im just feeling compelled to do something for my car. Has had a few issues with idiots in parking lots of lat, few scratches. needs some TLC.

Also my mother coming out in me, wanting to buy something coz it is on sale/cheap =p.

Not a fan of overly noisy cars, i seen some very quiet cruising, but loud under accelleration. It be the only time I'd be pleased to hear it. To know the car is reving nicely, without having to look at taco etc (auto).

But dont need any grief from cops. Guy at the servo told me to get a locally made one, so that it is under EPA limits.

And yeah, i;ve read you dont need noisy exhaust to get power. which is why im confused as what to get. I spoze i could just loiter outside some performance shop and listen for a car that suits my taste.

non turbo motors drone a bit more a think

if its auto gts-t it should sound ok. u don't sound like you want a really loud system anyway, just something that sounds nicer than stock and looks good. you'd probably want a system with a rear muffler and also a centre muffler, which would still sound nice but not too loud or drony.

you cant go by size of the exhaust when talking about the Jap brands and relative noise..

also other considerations such as mild steel or stainless, mandrel bent or press bent - they all add up to the noise factor.

Not to mention the engine, dump pipe and overall setup the exhaust is being mated to !!

I have the HKS Super Dragger II exhaust - which is one of the largest tips/mufflers you will find (5 inch), however the noise is considerably less than other similar setups..

If you are looking at a Jap exhaust and dont want noise, consider ones with dual mufflers...

i wouldn't risk going too loud in melb.. you'll get EPA'ed pretty quick. I got EPA'ed for a perfectly legal 89db exhaust (see the pic.. lol)

Like Gizmo73 is saying, there is a lot more than just the size, the amount of bends, the angle of the bend, extra resonators, or muffler can all effect it. There is no "standard" way to say how loud it is just by looking at it.

You can ask brands, and you might get some feedback.

    • Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers    
    • Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.
    • Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.
    • I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.
    • Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust
