ok heres the deal i beleive the car im getting from Japan has an aftermarket exhaust system but i want to get a new one for it when its here in Aus. I know there are tonnes of threads on this shit, but its mostly diff questions... I think :D

Q1:Im tossing up whether its worth going an Aftermarket Exhaust system or go to ET(or other SA exhaust specialists) and get a custom done? i know customs are cheaper, but performance and sound wise what are these like?

Q2: Does having an extra 50mm in length from the 4 doors, cause any trouble with aftermarket exhausts fitting wise?

Q3: I am wanting to have about 150 to 170rwkw as a goal, what is recomended to get done to the exhaust system, how much should i spend on exhaust system instead of other performance parts??

I think there is other stuff but ill put it up later.

q1: it would depend on the quality of the custom system obviously . a known aftermarket system is atleast proven

q2: on the r33 sedan the exhaust fits but sits foward in the rear bar . on my r34 sedan the 2door exhaust doesnt fit and had to be modified , a small section of 3inch pipe was welded into it . no big deal eitherway . even if it does fit like the r33 4 door you may want to extend the exhaust to the proper length so it looks correct .

q3: you want a full 3 inch mandrel bent turbo back exhaust , that means dump pipe , front pipe , hi flow cat converter and cat back exhaust . Additionally you want one with the straitest path and least restrictions with a sound level you can tolerate

check out justjap and their x-force exhausts , for the price they are pretty good . bit loud and droney but perform very well

cost wise full turbo back with cat should cost you 800-2000$

You are obviously looking for a mild steel for under $1000, over $1000 for stainless.

You might be able to get some jap kit for approx $1000 in stainless 2nd hand or new.

But thats always without a 3" cat.

If you only want 170 anyhow, just get it locally made from Mild Steel.

Will cost $1000 tops including front pipe and a cat, will be resonably quiet too

Yeah dude common myth that coupe exhausts won't fit 4 doors. They'll fit, it's just that there is one rubber sleeve which doesn't meet up with the 4 door. So hunt around.

I've got a custom one and with the right mods, manifold, cat etc it sounds fu&*ing SIK!

So don't fooled into spendng large amounts of $$$ for a brand name exhaust. Just got to do the right things to get the right noise!

I had D&T do my exhaust, full s/steel turbo back with a 3" s/steel tip, no milo tin style. Sleepy looking.

BUT.. They stuffed my dump pipe, the bloke who made it had NFI, he didn't stretch the pipe over the flange correctly resulting in a 10-15mm V type rise smack in front of the compressor wheel, where as it should be flat then follow the dump pipe down smoothly.. If that makes sense.

I'm taking my car back to them soon to have a s/steel center muffler fitted and the resonator removed, help quieten it down a little.

I'll also get them to do a back to back dyno run to see what sort of power drop there is. I doubt there would be much as its a nicely made 3" straight through muffler.

hmm i love the jap brand exhausts but i dont really think you budget is there for a full jap system maybe x force is the go for you, going from what ive spent on my exhaust 1000 wouldnt get close and from other friends systems too they where anywhere near 1000,

for instance just my cat back cost 950 its a blitz and its excellent the only thing i would maybe choose over it would be a trust system one of there racing ones then, you still have to add the cost of high flow cat front and dump pipe onto that!

I paid $1600 for mine. :S

Mild steel was quite a bit cheaper. There were other exhaust shops and second hand jap exhausts. The problem was I didn't like what every one else was offering.. Milo-Tins. :P

I'm having the center resonator removed and a s/steel muffler slapped in its place, $250 D&T want. Should bring it down quite nicely.

Since the slightly larger turbo went on its fairly loud, not too lound but too loud for my liking. I prefer a quiet car where I can give it stick and ppls won't instantly look over.

is there anyway of having an exhaust system that has a low db idle, but roars when u get the revs up a bit. whats the best way to get this??

Get an adjustable exhaust valve....

A'pexi ECV.

Don't know how good they are, only that they exist

Mine is very quiet on idle and light throttle.

The car next to me with the window up my car cannot be heard.

Give it a boot full and you hear a roar.

BUT its still too loud for me, I want as quiet as I can get it without causing too much of a restriction for up to 280rwkw.

Mild and s/steel also have a slightly different sound.

S/steel drones a little more, mild tends to be just that little bit quieter.

32 sedan and coupe are the same

Good brand name systems can be under 1000

check out trust and blitz systems for 800-900 at autobarn, cartoys etc.

And with that goal in mind, an exhaust will be one of the major modifications.

    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
    • This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.
    • Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
    • To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all
    • 300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
