Thing is though, the Racepace exhaust will pass... we got mine passed eventually, i was basically the test mule.

I must have had 5-6 exhaust noise tests, maybe more, cant remember :P

So while the price is high, there is a fair bit of research/work and otherwise that's gone into it as its all custom so its the biggest you can get, while still flowing.

I reckon with two brand name mufflers, you'll probably get close... those last 2-4 dB are the hardest to knock down as i hit 92 about 4 times with various changes.

So you can either go a stock exhaust (thats been... assisted) and pass, or get something made that will always pass.

Once you cop 2-3 EPA's, the less hassle/more costly option suddenly looks a lot more inviting which after my many many EPA trips, was worth it to me.

Each to their own on that one, depends how many times you see the EPA i guess before you get sick of it

Yeah i def want the racepace exhausts they are fantastically built and make great power while being quite... but like u say its that 2-4db that is hard to get down, ben said the same thing that it will get really close but not under 90... so my plan was to borrow a stock exhaust get the test cleared then get ben to build my system, it will be a little over 90db but the cop would have to be a sonic freak or just an arse to give me an epa test at 92-4 db. its just getting the stock exhaust from somewhere... the cefiro guy seems to have dropped off the plannet and i don't really wanna pay the exhuast place guy $300 to make me a plugged up system.

92dB isnt like 102km/h in 100km/h zone and being 2 units over.

92dB is actually 2 times louder than 90dB, so if you put 90 & 94 together there is a very substantial difference. :D

We got mine down to 86dB on back off, have a chat to Ben about it :P

My first effort was 92dB... RB's are VERY hard to get quiet due to the frequency of the exhaust etc. Its the bass that sets it off.

I also recommend taking your car to the tester in Lilydale. Yes it might be a fair drive from wherever you are, but there are factors that seem to impact the tests and their location is the best for it

PM me if you need more info or cant make sense of my post :)

While im here... Join SAU-Vic, you know you want too and we would love more Stag's ;)

Cheers

Well after a first great initial responce... i still don't have an exhauast, which is a bugger as i really am left with no choice but to get the exhuast place guy to make me up a silent system that will make 0 power... pass the test and then put my old on back on. Oh well, i guess thats what happens when u own a rare car

Have a good christmas everyone

Im screwed!!!!

Got a letter a few weeks ago, I was in a shop, and mate comes in after 15 mins. He states to me cops been sitting behind my car for the past 10 mins. I was in a pickup/drop off park. Went out there and they were gone. Thought to myself. "Well, that went well." Got a letter in mail two weeks later stating my car was spotted driving in a particuliar street (load of shi..), and that the exhaust needed to be tested due to a certain police officer thinking it was 2 loud.

Fair enough. So went down to exhaust centre gave them a 2 1/2 muffler and said could U mount this and weld up half of the 2 1/2 inch pipe (3 1/2 inch into a 2 1/2 inch), to quiet it down enough. $260 later, did a great job. Went in got it tested 89 db. Woo Hoo passed. Got home removed muffler and put my bad boy muffler back on.

Mrs borrows the car! The other day to get to work, guess what! Yes, massive police blitz on Calder Highway on incomming side of Bendigo. Get the phone call from Mrs. "They about to do a EPA noise test on your car." Not good! Got a reading of 113 db!icon8.gif

They didn't know the car had just been through a test a gathered. They didn't ask her about it, but stated that I would be getting a fine maybe in the mail. I gather I will, not to sure how BIG yet. Heard a bloke got $2500 fine fore removing his CAT's. I will eventually get through this in the end.

Just to make things worse, my clutch shi... itself today (nismo twin-plate spring button clutch) done a hole 15,000 khms since it got re-conditioned. <------------DODGY AS!icon7.gif

Anyone had this happen to them before, or simular. Any advice would be muchly appreciated.

WHITEBEAST.

yeah i took the mid muffler out so i could atleast hear my car ....

if i get done ... just slap the stock system on and bada bing bada boom :D

i have thought about dropping my mid muffler, maybe when its manual :D

I just got a new 3" catback. The old setup was very quiet. Had a huge oval mid muffler and a 10" dia cannon that was only a 21/2" with a 5" outlet. Looked hot but was useless.

The new 3" has a 5" dia mid and a full flow 3" cannon but just 6" in dia. The outlet is double wall so it can't melt the bar.

It is noisier but I dont think too much. I reckon it would be legal, but I will get it tested.

Engine breathes a heap better. Cost $500 at GC Mufflers.

recently we stuck a 3" straight thru custom made 10" x 8" x 19" monster mofo rear muffler due to ms wolv wanting NO NOISE at all (replacing a twin outlet 10" x 6" x 12")

the muffler looks like something off a prime mover but it is super quiet. it sounds quieter than stock to my ears as there is no tell tale RB over-run noise coming into the driveway at all.

the rear end of the stagea has so much room so they are really easy to get the noise down.

cost $280 plus fitting.

Didn't Know this thread was still going!!=

Well i have got my exhaust all done now, full custom 3.5" system from racepace. Twin tips out the back looks reasonably stock, sounds great quite on idol/cruise but sounds unreal under power. Ben also found a split hose which he replaced and turns out it had been causing troubles for awhile. So after a total remap, retune with exhaust and new pipe she is now putting down 263awkw :);) and goes and feels like it wants to go into orbit! i love it. A BUTT load of cash down but so worth it...

Anyway I still have the rear pipe/muffler i had made up so if anyone needs to borrow it for a test give me a buzz :rant:

Cheers

    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
