hey guys i was wondering what size exhaust would be best for my n/a r34? 2 & 1/4 .. 2 & 1/2 ??
would extractors be a gain or worth it?

would it be worth getting a hi flow cat ??
im looking for power increase i know that not enough back pressure can have power loss...

help is much appreciated!! :)

thanks in advance.

regards, Giuseppe

.... Oh god, it's one page back just look.

I'll make it simply, the exhaust is a waste of time for powahhhh it's just for noise wank factor.

2 1/2 inch with a twin tip muffler at the back and a single resonator... It'll be loud and droney have fun

Use the search button. This is the second incredibly pointless and numerously answered thread you have started. Use the search button or go through a few pages. The N/A section is basically 5 questions asked 200 times.

Exhaust = wank factor. End of story. N/a twincam skylines sound like crap anyway. They rasp, they drone, they have a terrible throaty noise in the low revs and have will not impress anyone. They will sound better with a stock exhaust, trust me. If you're so adamant about noise, then put an aftermarket pod filter enclosed in an airbox. The intake noise is more than enough noise and the car will sound better then if it has an exhaust on it.

Put a varex rear muffler when you are around town and cruising on the HWY. RB doesn't sound that great when driving "normally" (under 3000rpm), sounds similar to an old Falcon. Sounds awesome when at higher revs though.

But yeah +1 for stock

I'm running from the extractors back: 2.75" mandrel bent piping, hi flow 100 cell cat, resonator and a kakimoto muffler, (not a cannon).


It's sounds pretty quiet at idle and has the traditional RB sound from 3500rpm and below but once I go higher you can tell thats its definitely an N/A. (Sad face).



I've had comments on it that it does sound alright on the highway and when I give it the berries as well. (On track or private road of course.)



It makes cracks and pops from time to time too which I like as well :)

Stock system will reduce thy raspyness leaving a quiet car with intake noise which is the only noise that will sound good on your car.

According to you

No, I'm fairly sure that's fact actually.

According to you

Well you must be a minority then if you find the sound of an n/a skyline's exhaust note pleasing. Like alot of straight 6 BMW's, twincam RB motors are awfully raspy and droney in n/a form. The only real way to counteract it is to have a quiet exhaust system, or even better stock. Instead of putting up with the horrible raspy drone from an n/a, ive found it more enjoyable being able to cruise in peace and quiet. If I want noise, then I will get a pod filter in a box. Plant the car and all of a sudden it becomes brutally loud and has a nice throaty intake sound that believe you me, with a QUIET exhaust can actually be heard a hundred or so meters in front of the car. Intake noise is always drowned by loud exhausts, people dont know what they are missing out on imo lol.

Chicks get wet when they hear the mighty sound of my pod filter when i punch the throttle. This is on my 1998 mazda 121 metro. And thats before they find out my wheels are infact JDM mazda mx-5 enkei alloys!

Offset >40 with brake clearance makes the wimminz moist ;)

No, I'm fairly sure that's fact actually.

So you've heard my car before have you?

I wouldn't drive one if I didn't like the sound of it. Don't like it? Then don't get one. Simple

I can cruise in peace and quiet too. The sound of the RB is my peace and quiet.

True story!

Though need stainless intake pipe to attract teh 9s and 10s.

    • I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀   
    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
