Justjap Split Dump Pipe

[darrinspencer]

Darrin, as far as I am aware, you need a split dump for an R34 to fit the Stagea, thats why your pipe wouldn't have fitted. Just Jap only lists them for R32 and R33 GTS-T and the one I bought for my R32 some time ago fitted straight up, with none of the issues you have mentioned, and I checked it the other day while my car was up on the hoist and everything in a-ok.

I have no dealt they fit R32 and r33, because that is what they were designed for.

I had no problem with having to extend the vertical section to miss the floor, but I do have a problem with the warped flange. I am not prepared to fill the gap with sealant. It is that bad.

When I ordered the pipe thru JJ, Daron was not sure which one exactly fits and had mixed reports from customers. So he agreed to send me with with the chance of a refund if it did not work. so that thats what will happen.

R34 dump pipe is longer by approx 20-30mm and has a extra mounting bracket which could be cut off if not needed. I have not measured or compared one to a R33, but that is what I have been told by JJ

All the people that have fitted some sort of dump to a Stagea have used R33 ones.

Just to be clear, this thread is not to put down Justjap's products or quality, but to simply find a solution to my problem. Justjap's understanding and service has been great.

So bascially I am back to square one.

their service is good, quality is generally 80% good tho..... with my bellmouth had to have the flange rewelded, too many gaps due to shitpoor quality weld. didnt cost much.

flows real well, and fits fine :laughing-smiley-014:

This pic is the JJR split dump. Note that the pipe is straight as circled and this is where it hits the car.

The second pic is JJR bell mouth design. Note the is a offset in the straight pipe which should miss the car

This could be the problem?

Also spoke to Bosimporting and they told me that I need a R34 dump for the series 2 and r33 dump for the series 1.

This does not make sense as they are they same floor pan and the motor and turbo are in the same position.

But the r34GTT dump is 20-30mm longer in length and the cat is also longer in a r34 GTT. So why would it fit?

[darrinspencer]

Had a look and compared a R34gtt bosimporting non split dump pipe tonight to the R33 JJR split I current have

The R34 dump was approx 100mm longer than the R33 one.

Also compared the R33 JJR pipe to the standard series 2 factory exhaust and the length from the turbo to cat flange was the same.

So a R34 will not fit.

Will have to find a R33 one that will miss the floor.

I finally got a dump pipe to fit

I used a R33 Xforce bell mouth dump pipe

Fitted pretty good, but had to create a bit more clearance by removing approx 3-4 mm from the end of the gearbox cross member and massage the floor where the gearbox cross member bolts on.

what a PITA process that has been.

did we end up confirming anything to fit a S1?

I've got mine ready to be put on, Duncan. Care to help me? I've got the jack, stands, tools and the space - I just wish the garage wasn't so bloody cold!

[Duncan]

lol why not....we are playing cars on the weekend atm I'm just not chaging any studs that break

S1 would be the same

The main thing learnt out of this, is what ever dump you use it must set down lower to clear the floor and then set back up to cat converter, ie not run straight to the cat.

I have a BOS imports split dump to go on, I know of at least one Stagea S1 owner that has fitted one of these with no issues so I will let you know how I go. The section of pipe heading towards the cat definitely does have a dip in it though so maybe that is the difference...

I spoke with Bos importing aswell. He tried to tell me I needed a r34 dump for my series 2 not a r33.

R34 dumps are longer and a different shape under the car. It would have not fitted. Another SAU member in Brisbane has a R34 Bos pipe for sale which I had a look at and it would not have worked

I also spoke with Alexcim about his Bos R33 split on his car and even though it fitted, it still had clearance problems. Also spoke with Rev210 about his JJR split on his car and he had clearance issues aswell even though he still fitted it.

So out of all this, until someone makes a stagea specific dump pipe, the ones that are off the shelf for r33's are not a perfect fit.

so after all this, does anyone have a surplus mild steel bellmouth dump/front to suit r33 they need to sell, to me, cheap?

They only have the split type for $250 and the Xforce bell mouth for $330 now

You can also now get the s/steel split type (same as the JJR one) for $199 on ebay from another seller, but only good for r32/r33

Installed my BOS stainless split on the weekend with NO clearance or alignment issues. This is on an S1 and is a fairly late model split pipe, so it worked for me, which I am really happy about.

Note the huge clearance between the pipe and the aircon line, this is one of the things that was changed in the design of the split.

It comes close to the rear gearbox cross member but not too close, it won't hit it. The exhaust could be 40mm longer on total to be perfect but it's pretty good, just pulling forward on the rear hanging points a little and it is close to the rear sub-frame due to this. On a quick test drive nothing touched or rattled so I'm pretty happy with it as is.
