huh? that's wierd, if boost increased when you made an exhaust change, wouldnt this indicate more of a restriction?

that is, the backpressure can't escape quick enough, which drives the exhaust wheel faster, which drives the compressor wheel faster, which increases boost in the intake side without any change

Other way around.

i've got a full exhaust on my GTR

Mines Dump Pipes

aftermarket front pipe (Stainless)

hi flow cat(stainless)

3in stainless cat back with oval muffler

the dump pipes arent needed, i only did mine cos i changed the turbos, and though "may as well"

just get a aftermarket brand front pipe, good hi flow cat and ring around a few exhaust shops and get them to do a cat back.

i didnt really worry about which brand to use, its all just metal, and just as long as its all mendrel bent youre fine.

and when it comes to sound if youre that picky, try and find a muffler that will give you the note you want, and if you need you can always chuck a hotdog in to deepen the note if need be.

good luck mate,

i'm sure youre gonna like what you get, i know i love the sound of my exhaust!

At the moment im running Tomei manifolds, HKS dumps, HKS front pipes 3.5 inch cat and a Kakimoto Full mega N1. Pretty damn quiet at the lights and driving.. NO drone what so ever. On boost... My god what a noise!!! I couldnt believe how much difference the cat back has made. I had some 3 inch "cut and shut" system on their before.... Just with the catback change i reckon its going better on 1.3 bar with timing pulled out of it then it was on 1.7 (2.8 stroker twin GT RS's). However it wont be cheap as previously said :P

Hey guys, on this subject, I have a GTR with a pair of 2860's, with CES split dumps to Y-pipe to 3.5" hi-flow metal cat. Basically my old exhaust (unknown brand, 3") was reflanged to fit the cat.. What would you guys suggest I get? I'm past my "run in" stage on my new motor, so I need to get my final tune done.

Thanks for your suggestions! :D

Kakimoto Regu 06+R or the Full mega N1

Man your idea of not loud must be way different to mine or some how the top part of my system must do some nasty damage. I have the Full Mega N1 (single pipe not twin) and without the additional baffle pipe in the cannon (inner silencer) it is a cop magnet - loud and on boost I agree awesome but really loud. Top part is a custom 3" bell mouths off turbs to 3.5" collector to 4" metalcat to N1.

Cheers

^^

Well when i bought the system i was pretty worried about how loud it was going to be at idle and say sub 3500 RPM. Started the car and it just purs. Ive had a mate drive next to me and he said he can hardly hear anything. On boost it absolutely SCREAMS but without big revs adnd the gates not open its quiet as.

  • 4 weeks later...

Hi, know nothing about exhausts. Am going to look at one tomorrow.. XForce apparently 3" to cat (xforce cat?) and 4" rest of the way + full stainless. Its at a good price so I'm pretty much sold on it unless someone can tell me different? (To suit GTR33)

Also, is it going to loud as hell?

Cheers guys.

Can someone confirm before I go and buy it please...?

4" from cat back will be pretty loud, I have a Trust Power Evolution 2 (94mm but close enough to 4") and it is pretty loud, you will get defected.

Depends if it is 4" with a few decent mufflers in there to be under the dB limit?

Cheers, dont have much info atm, just what i said above. I'd be going to buy it today but haven't got a ute atm... Getting it tomorrow in a hatchback :rofl2:

I would find out a bit more info before you commit and hand over cash!

380kw has been made on stock 33 GTR dumps with 2560 turbos.

Im changing back to standard GTR dumps because my stainless HKS split dumps are giving me creep. Also running 2560s.

Im also running a HKS Dual Racing Exhaust, its a full twin which never joins. Tuned length dual.

By changing from a single 3.7 HKS Super Dragger to this exhaust, boost shot up to 23psi from 17psi with no other changes! Let me say it must flow very well!!!

I have R33 GTR Dumps for sale if you need them, the R32 ones are crap.

P.S CES have the worst customer service in the world! dont bother with them!

Was the twin system much/any louder than the single?

I am looking at changing from single to twin system possibly.

I would find out a bit more info before you commit and hand over cash!

It's also apparently 2 months old. I'm mainly going for it cause its only $250 and its all xforce. I had thought 3.5" was the max one should run. Will 4" be unbearably loud cause this is a daily driver...

I rekon twin systems are the bees knees. if you have one direct exhaust path for each turbo it will not only help flow issues but it gives you more room under the car!!!

I agree, with the first bit. But I think you will find there is less room under car, perhaps slightly more clearance to the ground which is what I think you mean.

When I get to the point of upgrading turbos twin 3" all the way to the back of the car... wooohooo!!!!

"Ten Four" for $250 you can't really go wrong, buy it, fit it, if it is too loud for your liking then f**k it off for something more suitable.

Cheers mate, bought and collected it today (had a dent so i got it for $150 lol). It's basically a complete xforce system inc cat. Has middle muffler and rear. Question: Will the whole lot bolt up to stock front pipes or do I need to get some to suit? (Last question and very thankful cheers.)

Here's a awesome paint diagram to help explain..

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • 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
