Dump+front Pipe

[R338OY]

Hey all,

I'm looking around for a dump+front pipe setup for an RB25 with stock turbo. I'm told a split dump will be better than bell-mouth as well.

From what i know there isn't much point going all out nuts on a stockie turbo, but i don't want to regret a cheapo purchase (i.e. JJR stainless) when something a little dearer is the better option (such as CES), i.e. adding an extra $100-200 and getting stainless, or ceramic coating.

I have a mild steel Fujitsubo cat-back at the moment with no plans for turbo upgrade for a while.

Any suggestions for a reliable, reasonably priced setup with the aim for a pansy 200rwkw?

Thanks

Any reason why you dont like the JJR one?

Omar,

I just have the single 3 inch dump/front pipe in one.

Works well for me with my hi-flow turbo set up etc.

Before my hi-flow set up I was making just under 200rwkw with it.

However if you are planning further mods later (turbo upgrade) I'd now suggest a hi-flow cat also. I have standard cat with my set up and it is robbing me of some more grunt!!d'oh!

Also - I havent had the split pipe on before or done any testing so cannot compare !

I think Liz had both on her old 33 - hope she see's this thread

Cheers,

Chris

I'd get one. Just unsure if there's better options.

Do you recommend JJR?

I was hoping maybe you could shed some light into the matter as i was looking at one myself haha, but if you had a good reason not to go there id keep hunting!

I guess it depends on what you want to spend! I mean the HKS front pipe alone is around $400, and with that you still have the stock dump pipe..

For the price personally it looks pretty dam good! Especially as its a split dump pipe, and front pipe in one. And will directly bolt up to OEM turbo and cat/decat.

Ill just go ahead and get it and let you know.

Get one of these babies from AM Performance in SA, im sure he can send interstate, they do Split pipes in screamer style or return to exhaust which would be best for street. Quality is top notch and they wont leak between the turbine and the gate!

[white33gtst]

just adding to this thread, would it be beneficial to include having a small flex pipe in the dump/front pipe? gktech sell ones with flex pipes like this:

R33 front pipe with flex

ive also been looking at the JJR dumps but without a flex piece in the piping, just wondering if there is benefits with having the flex piece there?

Do they have a webpage? Will be interested to get a price on them, if he will ship to NZ

Batmbl sell good ones Omar, Just japs are also fine.. Just as long as its not an xforce one you'll be fine.

Mines a custom ceramic coated one which is why It sounds so deep, so Id suggest it being ceramic coated, if you can find a second hand Ces one that would be good but unessasary as they are designed for some decent power.

The belmouth actually will flow more with bigger turbo applications, but the split dump makes the car sound better with a stock turbo.

If your like me with no need to upgrade the turbo then I think any will be fine if you ceramic coat them or heat wrap them.

A high flow cat is a obvious need too. I have the Catco one from Batmbl and it flows great, alot better than the stock one.. again dont get a xforce jobby.

[NVE57]

whats with x-force? are they a cheaper brand or something? has anyone had any issues with them?

[DECIM8]

They dont fit correctly, often never line up with themselves or other brands.

The cats dont flow at recommended amount, dont feel right.

Exhausts often stick out conciderable amounts from the rear bar of the car. but sound good.

So just a few points

I havent had anyproblems with mine. car makes 203rwkw with pfc on standard turbo so no flow issues either. Only thing i can say is it is quite loud. Might be bcos mine has a hotdog resonator instead of a proper mid oval style muffler. sounds great though.

Are you saying i should ceramic coat a stainless one too? Or is that just mild steel?

[DECIM8]

If you want to.. Mines stainless and ceramic coated.. looks slightly funny like a weird polished silver but you'll never see it.. Just drops temps in the engine bay.

The xforce cats are really bad at flow.. but thats a nice power figure.

So Nat you're saying i.e. buy a JJR and get it ceramic coated?

Sounds like a decent idea actually.

Yeah cat is on the list too. Hoping RSPCA can get me a cheap one.

I checked BATMBL on SAU and saw their split dump+front pipe. Looks pretty good, but you said yours is custom? What did they do differently, the coating you mean? I'm happy to add $100 over JJR and get the BATMBL one, sounds better quality steel (plus you recommend).

So the Catco was good for you? I'm not gonna go nuts on a cat (i.e. i'm not fussed if its ceramic/metal) cause i'm not gonna upgrade the turbo for a while, if ever (he says with a hint of doubt lol)

Are you anal like some of the other SAUers and insist on a metal pussy?

Convince me and after my exhaust manifold is fixed (next week) i'll head straight for the turbo-back

Good to have some advice drawn from experience

On the dyno my CES dump actually brought boost on quicker and made more top-end than the bellmouth....they both tragically had boost drop-off, but hey that was related to a sucky-closed intake pipe :S

[gotRICE?]

Hey, i just ordered my JJR one in stainless, when it arrives.. (maybe a week) ill let you know how it goes.

So you'd recommend a CES dump+front??

Yeh i was thinking it wouldn't make a big difference. I'm gonna stick with a split dump. Just wanna pick a good all rounder.

Thanks mate, i'm interested. If it's a great bit of kit then its a steal. I need convincing cheaper=better
