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.

my vote is the tomei dumps. much better made than the HKS once. plus they have a nice big bell mouth. the HKS ones have tiny primary and secondary pipes.

As above.

If I wasn't already using HKS versions, I would only use Tomei.

Outstanding build quality and nice big inlet.

so around 600 at the cheapest is the go for them???

I have just purchased some Tomei dump pipes, and will have some 5000kms old HKS dump pipes available within the next month.

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.

ummm merli. unless you are attaching them to the air purifier in your M3 then I think you have some splaining to do....

confess me your sin brother.

I have Tomei dumps also.

I used those Trust long front/dump combo pipes before and wont do that again.

HKS are good looking dumps too.

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.

have been tossing up wheather to spend money on dump pipes or cam gears.... what gives better bang for my buck?

[SysLink67]

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
