You would need...

CAT--Muffler--Muffler

You won't have room for a resonator one you get two big mufflers in there (you'll see what i mean once it's on a hoist).

You might even have to go down the road of custom mufflers to get them as big as possible, that is the aim, nice big fat sound absorbing ones

I'll freely say im outta my depth with N/A RB's. I don't know how well they drop in sound with various sizes exhausts, mufflers etc.

Turbo RB's however i've seen many configs that do/don't work, but as is said the turbo alters things. How much i am unsure.

Also with N/A's you don't neccesarily need "straight" through style exhausts far as i know (due to far less pressure in a N/A system), which gives you many more muffler choices/options.

I could again be wrong there... N/A performance, not my specialty.

Hopefully someone else can ride a white horse in and offer more

thanks mate

yeah already got a cat so all i needa do is put in a nice n big mid muffler and drop the cannon to something smaller as my previous post n ill make the legal noise limit

thanks for the help, hopefully all goes well...ill talk to another place tomorrow, wasnt too keen on paying the place i went to today 280 for a universal stock muffler wif crome tips they would put on after they change the cannon to the universal stock muffler.

thanks again

[R31Nismoid]

Well you might not be ok dude - perhaps wait a day or so for some more advice.

Others here might know more than i do on the topic.

If you don't make the noise limit after paying for two new mufflers - that'll be shithouse for ya.

[JPCR33]

yeah true mate....be a massive pain seemings i failed the on the spot test n they took pics of the car...so wont to do it correct now n pass n keep it like it forever so they cant dog me again

[R31Nismoid]

^ Excellent view mate - props to you for thinking that way - if only others did the same.

Its ok to get pinned, but to get pinned and leave it (just to get done again, and again), is silly.

I was the same years ago (silly lol) - put a stocker on and forget about it.

But meh, after 3 exhaust noises in 12 months, i'd had enough and eventually just got a new exhaust that's nice and quiet

People don't even hear my car pull up in the street these days, far cry from my younger/dumber years

Ash they were getting police to nab people on Deakin Ave and 15th streets Mildura (the two main highways through town run via these two), and testing at the local Centro carpark. AFAIK it was a one off, but they may do it again in future.

Silly really, because of the way word gets around about such things, most of the feral hoons leave the streets within 5 - 10 minutes of finding out about such things, leaving everyone else to get caught out. In fairness I was running a straight 3" pipe with a decat at the time lol, so ended up getting 106db lol. I luckily missed out on copping another 500 dollar fine for the Microtech in my car after discussing with Lou how shithouse it was and my intention to get rid of it (still trying to work out to get a stock ECU running with butchered loom etc).

They did 30 cars that night and I'm pretty sure every single one got at least a 500 dollar fine, and I saw a stock Subaru Liberty getting done (I don't know how that came under the classification of 'loud') lol.

They took photos of the exhaust and the car etc, I figured that if I at least have something with mufflers next time it's a start . I did get a v. quiet JASMA spec exhaust with two mufflers, but I'm starting to get sick of it being so quiet, so will likely end up getting a Kakimoto Full Mega N1 or something liek that.

i got done the other week in melbourne in broady by fawkner tmu.

They took pics of my engine bay and exhaust,i recieved the epa letter which states i need an emissions and noise test to be done at hoppers crossing or indy automotive in moorabbin.

My car is a s13 with a sr20 off its nuts in there atm.Im currently removing everything including aftermarket ecu.

should i keep my stainless turbo manifold or put stocko back on?

heres a pic of my engine bay im going nuckin futs atm

[KURAUN]

stocko on

pretty sure they can tell if there a diff manifold due to the flow differences as they are a fair bit different

[Bozz]

Aftermarket injectors - legal if the same size?

My problem is they're black and factory injectors are yellow. Any potential issues?

Cheers

[R31Nismoid]

black would look stock - so id say you'd be OK anyway.

Thing is, you need aftermarket ECU (or chipped) to run aftermarket. EPA know that. Is they see ye ole stock ECU no problems - they know you need ECU for it etc.

Worst case just say they are non OEM replacements, no problems running different brands - its the size change they care about vs emissions, something you arent changing

Is it legal to have a stock air box with the snorkel and panel filter and just not put the airbox lid to cover the panel filter?

[R31Nismoid]

well why you'd want to suck hot air in is kinda... well... silly.

but its still a stock aurbox

[boostn0199]

Nah was just wondering cause my clips are broken so was gona drive it aorund until fix it up

[MRSAMO]

I have the following in my R32 GTR

- twin Apexi air filters

- turbo timer

My car is a personal import which I had and drove in Japan. When it was checked by an engineer to be passed for registration there were no issues. That was 5 years ago, has anything changed since then? Never been stopped but a bit worried as the rules seem to change a lot.

[R31Nismoid]

Those mods are OK.

Sometimes you will get pinned for a turbo timer IF you leave the car unattended.

[MRSAMO]

Thanks!

I think the Timer definitely benefits the car in cooling down properly even for NA cars.

[MRSAMO]

Oh BTW, is there a helpful list of EPA-safe parts as recommendation that we can refer to. I know it could be a bit hard since it may be based off personal experiences, could be helpful in the long run.

I always assume that if a car is registered and has no problem in getting RWC then it should pass any kind of police or EPA inspection, but going by the stories here they don't inspire much confidence!

Maybe something like this :

Standard (all models)

- yellow injectors (250cc or whatever stock is supposed to be)

- ride height 15mm

- standard boost (I wouldn't know)

- Stock ECU (model xxxxx)

- Stock exhaust (2"?)

etc...

R32 (specific standard components)

- blah blah

R33 (specific standard components)

- blah blah

R34 (specific standard components)

- blah blah

No it doesn't.

yes, the EPA and VicRoads websites.

The documentation is VERY clear to be honest. There is no reason you should need to ask unless its unlisted - in which case it'll be in this list/thread pretty much

[MRSAMO]

No it doesn't.

Why not?

Direct links pls?

[R31Nismoid]

Why not?

If you can't take it easy for the last 5mins of your drive, then you need help.

I've never had a turbo timer, never will. Pretty much goes for everyone i know as well.

Links are all through this thread - i honestly CBF'd going through it. Have you even read the thread?
