You can either get the short type eg HKS or the longer versions which Trust make. There are also 100's of knock off version available.

The HKS type replace the existing dump pipes in your car & will tie into whatever exhaust you have. The Trust type tie into the exhaust just before the cat - so you don't need a front pipe. For me if I would buy the Trust gear instead of the HKS dumps AND front pipes. However if you have an exhaust with an aftermarket front pipe (many exhausts use the stock ones) I would just buy the HKS dumps.

The Tomei ones fit the same as the HKS type, but do not segregate the wastegate flow aswell as the HKS units.

Just about everything will fit your turbos.

why you changing so soon?

Pretty much because I like spending money on nothing :(

There's absolutely nothing wrong with the HKS dump pipes... They're brilliantly designed and pieces of art. I just want the higher flow capabilities of the Tomei dump pipes.

On a similar note guys.. when replacing the dumps you are going to lose the stock heat shields. How important are these and what are you guys doing about it ?

If its necessary, im thinking of wrapping mine in that fabric that keeps the heat in. I know theres ceramic coating as well but sounds expensive? Or are yas putting the stock shields back on by welding ?

You should wrap them in exhaust wrap if you intend to track the car in my opinion.

That or have them ceramic coated.

Correct me if I'm wrong Richard aka BB. I think it was you that once said "you shouldn't wrap your dump pipes cause it can cause cracking and increase metal fatigue by keeping the heat in the dump pipe by wrapping it"?

Is this correct? if so what can be done to keep heat out of the engine bay?

Also does the price of the Tomei dumps justify the performance gain?

The people that have fitted the Tomei dumps notice a "significant change" before and after fitment?

In terms of less spool up time?

cheers

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
