Front Dump Pipe Installation

[Andyn]

Hey,

I was looking at fitting a split one, and a reputable brisbane exhaust place quoted me $400 fitted for a custom mild steel split front/dump. This sounds like an ok price (correct me if im wrong).

Obviously its a no branded one, but these guys have been in the busines for ages so ud think theyd know what their doing. Anything i should be wary off and look out for?

Also i may replace the cat at the same time. what should i look for in a cat apart from bein 3" and high flow?

THe other option is to get front dump pipe from the forums (i.e justjap ones for $250 and fit them).

You could get the just jap one and fit it yourself. Cheaper and plus it'll be stainless.

Bit of a pig to fit but definitely do-able. Get a mate to give you a hand and it'll be much easier.

A lot of money can be wasted in paying for labour. Fit most things yourself and you'll save heaps of money.

stainless doesnt really bother me to be honest. think mild steel will last for quite some time.

Yeh since i have the factory gear on there some of the bolts can be a bitch to get off, if not snap. So I dont mind paying the extra to get it fitted.

I guess my question is whether all split dump pipes are equal, and whether there is any proof that the bos one for example which is closer to 500 bucks, has any noticable difference. Anything i should mentioned when they make the front/dump. I read somewhere that the join should be as far back as possible to minimise turbulence of air from the two pipes.

My 32 is pretty standrd with simple bolt ons and running 0.75 boost.

[RBwhatever]

Yeah me too. I got a mild steel exhaust.

As far as differences go, you'd have to run back to back dyno runs with the different pipes. I don't think anyones done that.

As you said also, the join should be as far back possible to avoid turbulence. Make it that way to be safe.

Also make sure they make an allowance for the O2 sensor, but they should know that.

It'll be a good idea to go for a 3" cat too if you don't have one.

Anything to look out for in terms of good cat? I hear the brand catco being used a lot in the forums.

Only 3", how about going up to a 4" cat?

Only if your pumping out big numbers. 3" is usually adequate for most applications.

You can if you want. But whats the point if you only get a 3" dump/front pipe? It comes down to flow. For your car you probably won't max out the flow capacity of a 3" cat anyway. Unless you got big plans for big power than go for 4".

I have the Batmbl Group Buy split dump on the R33GTST, works fine. I recommend wrapping with Thermo Wrap, it makes a noticeable difference to the under bonnet heat. I used to use Magic cats, but I tried a Catco (also Batmbl Group Buy) on the Stagea and it works well.

i bought my dump/split pipe 2 weeks ago and will be attempting to put it on this week the only thing I am concerned about is if i snap a bolt off the back of the turbo. Would I have to then unbolt the turbo and get a new bolt or are the welded into the turbo??

It cost me $80 to get my batmbl split dump and 5 inch metal cat installed.

Better than risking breaking a turbo stud in your garage... IMHO

Can fitting a front/dump actually take a decent mechanic about 1 hour to install? Wondering whether that rate u got was standard or a special price.

[RBwhatever]

With all the right tools and equipment yes. Taking into account he has to remove the old one.

[xRHETTx]

Yeah took about an hour, I watched the whole thing. Included 2 ciggie breaks.

[MANWHORE]

1 hour is taking your time.

No intake piping needs to be taken off, nothing. Just take off the heatsheild, under the bolts, and that's it.

It's pretty hard to break the dump bolts if your careful.
