Dump Pipe Front Pipe And Exhaust

[stasis]

Ok guys um getting really frustrated here. After hearing so many different comments about dimp, front pipes and exhaust. I decided to start this thread and get a clear naswer once an for all.

As most of you probably know i just bought a autech stagea 98 s1 series. The car is currently still in Tolyo ATM. Im gonna mod the car , mods cuch as air intake, dump pipe, front pipe and exhaust system.

The air intake im planing to use the Apex pod filters if not Blitz stainless steel type. Comments??

Secondly is the dump pipe , front pipe and the exhaust system. Questions

1. Will a dump pipe from a R33 GTR bolt staight on replacing the std dump pipe? Now is it worth it to get a dump pipe with a waste gate? in comparison in costs one with the wastegate and w/o it and the difference in performance? is it worth it? Called just jap today and they told me that they had a front pipe together with the dump pipe (pre fabricated beed to go to a muffler shop to weld it up on the spot).

2. Will a front ipe from a R33 Gtr (with the catalytic onverter as optional)fit onto the Rb26 ? bolt on staight?

3. If all the front pipe fits the end of it should be around on the transmission end. Then Will the angles fit on to the exhaust system from a Rb25 stagea straight up or have to muck around with the engles on the flanges? Or i need to get a RB 26 echaust system for a stagea.

I hope im not confusing you guys. Just trying to wiegh out my options before i commit my self. Thanks

I'll have a go at this first up...

Air filters: the apexi power intake filters aren't bad. they're fairly cheap to replace (as they're not cleanable),and work a hell of a lot better than the HKS ones do. I haven't used a blitz filter myself.

personally,I'd use two K&N pods. they're cheaper,easier to come by,and are cleanable.

as for the exhaust,my understanding is that the GTR front half of the exhaust will bolt straight on. as for the cat-back,you'll likely need to go custom,as the lengths and bends are slightly different to the coupes.

or,you could buy a system out of japan,and pay the premium.

split dump pipes DONE PROPERLY are well worth the extra cost over a blended style. the just jap/x force HKS copy units are NOT well done,and may even flow worse than the std cast dumps as the wastegate pipe comes in at 90deg. to the main pipe's flow,creating loads of turbulence. you want a split dump to come in much further down the system,along the line of the flow,not in on a cross-angle.

your best bet is to get under the car with a tape measure and start comparing what you get to GTR parts on the shelf in shops. that's the only way you'll know 100%.

ok about the air filters i was thinking of K&n at the first place then my younger bro said that the apex f;pw better but wasnt sue whether they are reusable or not.

So a dump pipe from a R33gtr will fit into the stagea 260 rs? Just jap offered me under $200 for a dump pipe which i thought ridiculously cheap. Now i know why i suspose. Just jap also offered me a set of front pipe and a sump pipe as a piece? How does that work?

My thoughts were using the the GTRs front pipe and dump pipe then let it connect to a aftermarket stagea's Rb25 cat back like a fujitsubo or something. Will the pipe on 2 ends line up properly w/o having to make modification to the flanges? i will be usinf a resonator if i can

mate, just relax a bit. The car in stock form will be nice enough for a while, enjoy it while it lasts. If you start with a modded car you will have nothing to work towards, if you know what i mean.

R33 GTR front pipes and dumps fit, not sure what cat and im pretty sure a RB25 catback fits.

What other cars have you owned, out of curiosity?

Mostly NA cars like BMW, Rx8 and a lancruiser 100 series (diesel).

I know what you mean Alex but i like to run cars more effecint as it can . Well put it this way i enjoy driving.

Alex you got a fujitsubo cat back havent you? on your 2.5t stagea? What i mean is will the front pipe able to connect to your fujitsubo? Cos im pretty sure im able to use the stagea Rb25 cat bak exhaust. get what i mean?

as said b4 gtr front end stuff will fit and stagea rear will fit, dont know if they will match exactly together as i havent bought an off the shelf system, but if they happen to not meet up exactly a visit to a local exhuast shop and they could adjust the bend to make em join up perfect for about $100 max, so that aint a big deal. or just buy a stagea 260rs exhuast system if u r worried about it not bolting staight up. they wont be any difference in price to gtr/stagea parts anyway, and the just jap stuff is mainly just china made, hence the $5 price tags on everything. remember u get what ya pay for and u soon forgot u saved $20, etc off the purchase when it doesnt fit and requires modifications to get workin.

the dump/front pipes bolt on the turbos and onto the gearbox so they should definately fit, and the stagea rear cat back will fit because its a stagea and the cat is in the normal spot same as gtr's so the bend might be a fraction out to join em but i highly doubt it.

no one here has purchased the gtr fronts and stagea rear section so i guess u gotta decide to risk it or just buy the full 260rs system and be done with it

good luck mate

Ok guys um getting really frustrated here. After hearing so many different comments about dimp, front pipes and exhaust. I decided to start this thread and get a clear naswer once an for all.

Wishful thinking if you think that this thread won't get just as confusing. :

My 20 cents worth.............

I would never use anything but a split dump and engine pipe combination, from what I have seen the Trust ones (R33GTR fits Stagea) are the best so far if you are after of the shelf. Performance Metalcraft make a better set, if you are prepared to leave your car for a week while they make them.

Magic cats (4" OD) are $210 on the Group Buy, all Skylines and Stageas use the same cat configuration.

Stagea cat back exhaust is longer than any Skyline due to the wheelbase and rear overhang, any Stagea designated cat back will do. Personally I would go for nothing smaller than 3.25" OD and shutting up a 4" system is not easy.

IMHO pods are useless without decent heat shielding and ambient air feed. They simply make lots of noise, are illegal, don't fiiter all that well, let in heaps of hot air and cost lots of power. I would use a Pipercross panel in the standard airbox, they work very well up to 300 rwkw based on our experience.

The best power up fuel economy mod you can make is a Power FC, do it sooner rather than later.

cheers

OK

For pod filters im planing to use K&n with a custom made airbox from an engineering shop. Shouldnt cost that much. im estimating roughly $200 max. If it does cost more probably i will use a drop in replacement from K7n. I have always used K7n for the last 10 yrs or so.

now the confusing bits. Starting to get the picture now. Im planing to buy a front pipe from japan at yahoo auctions. Its made up of SS and the size is 2.5"x2 into a 70mm. and a cat back fujisubo 3". Would that be sufficient? I dont want it to be too loud cos im expecting my 2nd child this year. So everything i do have to be as "bang for my buck" theory Do i have to get a hi flow catalytic converter for it?

Now the front pipe is made specifically for a 260rs but the cat back is for a normaol stagea would it match up piping position wise?

BTW my car will be here in about 1.5 mths at max. Cos if you pay your car to shipped in a container you get to jump the line at the japanese port. extra 400. I thought is good to let people know this

Thanks agin

guys i just bought a HKS front pipe from yahoo auction. It specifically for the 260 rs. So no confusion there. Does it matter for which Catalytic converter i get? (length wise? Im thinking of buying a catco w/ ceramic core that have been used roughly 20,000km. Its from a r33 with 3" piping steelbody covered in SS.

If i get the cat converter will it effect the length at the end?

Ok heres the olan

260rs front pipr (it says for competition use dont know whats the difference between it and the normal one)

r33 catco cat converter

a normaol aftermarket stagea exhaust

All are 3" piping will it fit length wisebecause of the r33 cat converter? Thanks

[beastien]

It should fit mate, i bought a cat from bosimporting to suit skylines, and fits perfect on the stagea

I too got a Catco cat from bosimporting - just the 3inch unit to fit Skylines.

With a rs260; youd want a 4-5inch cat, surely!

If i get a 4" piping all the way wouldnt it be too loud. cos i have my 2 babies with me in the car you know. Thanks

You guys think that is it worth it for a 2nd hade cat with a ceramic core? He wants 4150 but will try to screw him down to $80 probably.

I am running a pair of HKS stainless split dumps and a nismo front pipe. Dont skimp on quality to save a couple of hundered bucks. Buy once, buy right. Do your research, unlike me with my coilovers -= eh SK.

Kris,

how much you got your spilt dump for? wat size? And is your front pipe for 260rs or for a r33? Thanks Kris

[BoyWhoCriedWolf]

Bought a pair of new ones for $600 from a person on this forum. You need to get GTR dumps. The front pipe is Y pipe which joins the two dumps into 1 pipe and then goes to the cat.

Hi ken,

then whats this thing ? Is this a dump pipe? If i switch the exhaust to 3" all the way do i need to up the boost? I prefer not to though. BTW i wbought a HKS front pipe. thanks

Thats a dump pipe.

The exhaust goes like this

Cylinder -> Head -> Exhaust manifold -> Turbo -> Dump pipe -> Front pipe -> Cat -> Catback

Ok thanks alex. then wats the pic on the right is? Does that means i have to get 2 of those dump pipe?

[Sydneykid]

This is an equal length engine pipe for an RB26DETT with a decent length of separation of the split dumps.

cheers
