Hey guys,

I am getting a brand new stainless steel 3" turbo back system with high flowed cat installed on my r32 tommorow. At the moment i have a very cheap 3" cat back that came with the car when i bought it. It drones terribly and at 80km/h i can barely hold a conversation in my car without yelling which is the main reason for the upgrade.

But what i was wondering, was will the new exhaust with dump pipe and high flowed cat give much better performance than the current system i have?

Cheers guys

Well turns out I wont be gettin system today because of delays, but the guy gettin it in for me confused me. I asked him if it was definately turbo back and he said no, but it has a dump pipe?? My understanding was that a dump pipe is a pipe from the turbo back to the cat, meaning if you have a dump pipe you have a turbo back system??

Is that correct?

not quite...

turbo bolts onto dump pipe then to front pipe, then to cat, then cat-back

an aftermarket 3" cat back won't give any power increase over another 3" cat-back

the difference will come from fitting a dump/front pipe and the high-flow cat...

good luck,

Warren

I should've clairifed.

Turbo back system consists of (in order of fitment)

Dump-pipe:

Front pipe:

Hi flow cat:

then

Catback + mufflers

You can also get front+dump pipe all in one pipe.

Thanks heaps for the help guys.

I'll have to wait and see if i have got a dump/front pipe all in one, but im thinking it will be, cause i looked on the website for the company that make them and it says 'Full turbo system'. Heres hoping anyway, im thinkin the entire system should resemble something like this...

i fitted a front pipe and dump to my r33. it already had a cat back, made a huge difference to the overall power of the vehicle, u will certainly notice it, as well as the increased volume of the turbo sp00ling too :P

Gota love the sound of a turbo spooling, after i had my dump and front pipe put into my cat back system that was on the car from Jap it goes harder up in the revs and sounds sweet.

Cheers

hey,

Is it true that to modify the exhaust on the R33, changing the stock dump pipe is not necessary? I heard its quite good stock, so unless u got an aftermarket turbo a front pipe back exhaust will be just as good as turbo back.

Can anyone back this up?

Is it worth getting the dump pipe as well?

Cheers

Get a compleate system, if you have seen the stock dump its a peice of shit, thats why there is reasonable gains to be had.

So get any 3inch split dump?

What do u think of the cheap E-bay ones? Anything wrong with them?

cheers

r32line what kind of turbo back exhaust did you purchase?

and what do you all think is a better option for i: batmbl split dump front brand new + cat + second hand catback OR a full xforce system for $700?

From what i've heard SOME of the ebay dump pipes are okay, they're still a large improvement over stock.

Not sure about the HKS split dump pipe copies on ebay though, apparently BATMBL's longer wastegate chamber is better suited for reducing turbulence as it re-connects further down the pipe.

Anyone care to elaborate here?

I have always maintained the former. I would always go with that if I needed to upgrade a stock exhaust system.

I trust batmbl's pipes because they look like a good design, lots of people have made power on them and he's a good guy to deal with.

The second hand cat back you can inspect and make sure has no kinks etc and you can wash it out. For a metal pipe as long as it flows as good as it came out of the factory it's going to do it's job - it doesn't matter if some crazy Nihonjin has used it already :bomb_ie:

i have a front pipe from just jap, no cat back just the pipe so all u here is turbo spool lol, im waiting on my cat back rein hard thats on teh way,

my pipe was all one peice from turbo to the cat,

my front pipe lets me drive at alot lower revs and less "boggin down" around the streets, u can feel teh restriction when the flow starts moving more, should all change soo enough

    • My car is also flex tuned. It's worth mentioning it (the LS1 ECU) has a 1D table for E85 addition and just uses the ethanol stoich part as the second point of reference. It also as a 3D timing map for Ethanol adjustment. You would think this isn't enough but it works pretty damn well. That said, I wouldn't want it in turbo application. It's like lifting non-natty, or taking meth. It gets you unrealistic results that break down more things going forward. If people used it to make the same amount of power they do on 98 then it'd be one thing. But people use it, crank it up to eleventy million PSI, it doesn't knock - but it pushes the point of failure to another, more expensive thing to break. Every time I see someone make 280kw on 98 and 350kw on E85 on the same equipment I just cry a bit and really wish they would just stay on 98 in that exact scenario. It's bad for you. 
    • This is kind of what I was thinking but the temp sender wire and the two pressure switch wires run through the starter subharnes and I eliminated the two pressure switch wires completely.  @GTSBoy I have a can gauge with unusually bright warnings should the oil pressure fall so the factory light isn't needed. I need to dig out my wiring diagram and see if I can sort this out.
    • It's a valid point. And it is doable with the Nistune. But I'm not inclined to flex it the way Nistune does - certainly not on a Neo ECU. They're already pernickety enough to tune just one one fuel. And of course, I'm not that interested in putting in a Link or similar, on a daily. With the stock ECU, stock looking turbo, etc etc, I still stand a chance of surviving a run-in with the plod. Last time it went over the pits (which was for the transplant, for because of a run-in with the plod), the Nistuned ECU did not even raise an eyebrow. They want to see a stock ECU running the engine, and they are happy to see it do so without the check engine light** on. Never mind that the Nistune is necessary to make the stock ECU work in a different chassis without ABS, TCS, etc. **And they actually provoke the CEL to come on by disconnecting the AFM, to prove that the globe hasn't been pulled!
    • This is why you flex fuel it...
    • That is what I took from it too. Needed to go AWD S14 imo.
