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.

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
