I came across this exhaust:

http://www.ebay.co.u...=item3f1a3811f7

Would anyone know what noise level to expect from this one?

I don't want any droning or being unable to listen to music in the car. (that is with no amps installed)

Does anyone know how noisy this one is?

As an alternative I came across this one:

http://www.ebay.co.u...=item4845466ac7

But the diameter of the piping (rear end) looks kinda small to me.

Basically I am looking for a system which is good for 260-300RKW ..

Thanks :)

And I meant NOISY, not NOSIY ... :) :)

anything with an oval mid muffler should be reasonable, anything with 3" all the way though will be fine for that power level, going bigger will make it louder.

if its got a hotdog and a cannon expect it to be loud and drone like a bitch at motorway speeds.

if like the ones you have linked it has an oval middle muffler and a cannon rear expect it to be reasonable and unlikely to have horrid drone while cruising

if its got two oval mufflers expect it to be fairly unobtrusive.

Thanks ..

Seems like this is the one to go then.

Actually I was quite happy with the standard exhaust.

Having the cat removed it actually sounds a bit hearty and it is not loud.

However I now have a hybrid turbo and it seems the standard exhaust is

restricting the engine too much when upping the boost further.

Btw.

Is the Super Drager 3 inch all the way??

Mine is actually more like 3.5. Slight reduction at each flange

I to have this on my 32, it has a great note and not loud at all, mine is 80mm at the cat flange then steps to 85mm straight away, goes through the muffler to the next flange then steps to 90mm and the out through the cannon to a 5" tip, this car made 293rwkw with stock ceramic turbos, I looked for this system to suit the 34 cause I like the one on the 32 so much but couldn't find one so am going a custom copy of it

Great then, the exhaust 'sounds' better with each reply.

Now all I have to do is actually buy/win it.

I have a Trust downpipe which is 3'' or 3.5'' (?) and a HKS decat pipe which is the same diameter as the Trust.

Should be a nice fit ..

Would anybody here know what type of gasket I need for the connection of rear muffler to the rest of the system?

The gasket seems to have 4 holes for the bolts, but what would be the diameter?

I searched E-Bay, but no luck so far.

What turbo you are running will make a massive difference to volume.

For example I am running a stock rear housing highflow 3" all the way with a single rusted out large oval bodied muffler and it is loud but not super loud. My mate however runs a Gt3076r 0.82 with a 3" and a much better rear muffler and a resonator and it is MUCH louder.So just keep this in mind when comparing exhausts.

Imo if stock turbo a single large bodied oval muffler will do the job, if you are going a gt30 sized rear housing then two large bodied oval mufflers are a must.

Hi there,

I am running a HighFlowed OP6 turbine so nothing too exotic.

When I bough the car it had a HKS system with no middle silencer.

It was a nice sound (for race use), but too noisy for daily use.

.

I did not like the noise and installed the genuine exhaust system back on.

(actually the R34 exhaust, which is slightly bigger)

I have the Super Drager here now and I found it quite heavy (I though it was lighter).

The inner pipe diameter is 76mm (at the CAT) and about 84mm at the rest of the system.

Once I have the missing gaskets and exhaust rubber mounts I will install it.

(Not doing Exhaust--Goo) :)

The idiotic seller tied the 2 exhaust pieces together with a cable tie, and wrapped 2 layers of refuse bags around it.

That was what he called 'shrink wrap' / good packaging,

:woot::angry:

So it was metal on metal for the transport via UPS.

Fortunately the rear muffler took no damage, but I spent some hours restoring the exhaust's condition.

Here's the exhaust on an RB25 and the sound seems good:

There is gasket sheets you can buy from repco Think its acl from memory just mark out flange on the sheet hole punch the bolt holes out & centre cut the shape with tin snips *Make sure there Sharp*

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
