Just Installed My 3" Split Dump/front Pipe And 3" Catco Cat

Well, it's been long time coming, just never got around to it until now. I recently bought the 3" split dump front pump and a second hand high flow cat just to finish off my exhaust. After 2 days, and numerous trips to the local hardware store for tools, I've finally finished installing both.

A bit of history first. I bought my Skyline last year around this time and was driving it around pretty stock for a LONG time. First ever mod I bought, was.........drum rolls please!!!!!............A JUST JAP HKS COPY SSBOV. (it's a piece of shit, and worked for a week and I was a bit of ricer then)

Yes, I was stupd back then.

Anyway, back to the topic at hand, while driving stock pressure of around 7psi, I never really pushed the car into high revs. I then turned up the boost and installed the front mount intercooler and started trashing the car and found out at high rev e.g. anything above 5k, i wouldn't get much response....just a lot of drone and more drone and really couldn't hear much of anything else. So after getting used to the characteristic of the car for the last 4 month, I finally completed the exhaust.

It took me AGES to do, mainly because the spanners I had were of incorrect size and had to make 4 trips to the local hardware store on foot to get all the bits and pieces I needed. I might write a DIY for people those who are interested and a list of problems I have encountered along the way.

At 5pm today, I got everything installed and took it for a drive (8pm). The first thing I noticed was the response, it was definitely a lot faster response than what it was before and to be honest, public road is just not a good place to test out how good it really is considering that by the end of second gear, it;s around 60 or 70 ks already.

The second thing was definitely, NO MORE DRONING, just the smooth sound of the engine and the air flow. Now I wonder why I haven't done so 6 months earlier, silly me.

The downside to all of this, is that I can now hear all the "other" noises I wasn't hearing before. I can now hear the damn knocking sound from the fudged up shocks and some other strange sound that I wished it wasn't there.

Well, the next step is putting my SAFC2 to work and getting a tune. It's been lazying around in the cigarette tray for last few month its time to earn its keep.

After the tuning, I'm going to give all this a rest and stop spending all my hard earned cash.........yeah I wish.

Thanks you for your attention, hope you all can enjoy your split dump as much I will be.

Good to hear mate. I'm ordering a split dump/front and hi-flow cat in the next few days. Hopefully I'll be as happy as you are. Congrats, I cant stop spending money on my Skyline either. :thumbsup:

Nate.

not too sure about the brand, never cared anyway. For me, as long as it fits and works, it's all ok.

I guess I'll do a DIY once I get the camera back from the folks for better illustration.

I was pretty hesitant about doing ti at first as well, not knowing if anything needed welding or if my tools will stand up to the task at hand.

In the end, I decided to give it a go anyway and it was rewarding once that was finished.

hmmjust a few things that dont make sense my relatively stock skyline s2 r33 does well over 60-70 at end of 2nd? Are you only revving to 5000rpm? And also wouldnt exhaust be louder with these modifications? and hence it would make hearing 'fudged suspension' a little harder to do? Good to hear you did it all your self though good job.

Nice one James,

Only a few days ago talked to you on msn about it, so once you had the right tools, fairly easy and straight forward job?

still waiting for my dump pipe :P

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
