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

    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
    • There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.
    • yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
