Well, I'm not too far away from getting my exhaust system sorted.

I have decided on BATMBL's twin dumps, + large Catco cat @ $720.

Just not sure on the cat back, I am thinking of getting a custom job done

by Jack Beedhams but am worried about noise.

I am thinking of removing the middle muffler, getting new 3inch mild steel

maundrel bent pipe work, no resonator and keeping the stock rear muffler.

But I guess that won't be large enough, ie the stock inlet would not be 3 inches =

restrictive...

Does anymody know the brand that CES Racing uses? I know it's a SS twin tip

muffler but can't seem to google it with much success.

Also will this be legal noise? Perhaps even a good AM twin tip would not be enough

and I will need the 2nd muffler or resonator.

What's my best option for the catback, quiet but minimal restriction. Perhaps I can't

have my cake and eat it? I'd rather not spend more than $1200 all up and would really like to keep my 'sleeper' style with twin tips on the end.

General rule of thumb, the better it flows the louder it will be.

For $1200, I would recomend getting the best flowing cat back you can and fitting an Apex ECV. you can quiet the exhaust down any time you like, or go to full noise if need be and you want the power.

For example, I am running an SR20 with manifold and full 3" exhaust all the way back, it has a resonator on the end, but thats it. Its a N1 type setup, so minimal bends (bends restrict flow even if they are mandrel bends).

It is bloody loud. For daily driving I shut the ECV and it is quite inconspicuous. I have had traffic cops (bike cops and car) sit behind my car at the lights and not bat an eyelid. Works very well, and is also great if you are leaving your house early or late at night, you dont have to piss off the neighbours.

Something to consdier.

As for where to buy. Autobarn now do genuine Japanese cat back systems from blitz at prices pretty damn close to JDM. Can go wrong with something like the Nur Spec, just throw on an ECV and you will be able to have your cake and eat it. :(

ecv = exhaust control valve?, is this like the stock control valve that some GTT's have? IE you can operate this is cabin to increase restriction or reduce noise?

Autobarn says $729 for Blitz Nur Spec S problem is these are apparently 96-105DB (has a removable baffle) while CES claim 86DB. Not sure what legal is?

Fujitsubo make really good quality stuff, my exhaust was 1100 for the catback, have the split front/dump and the $440 cat.

The exhaust is the Legalis R, 84dB at 4800 and sounds SWEET. Perfect for a sleeper like mine. If you want a bit more power, get the SUPER R.

By the way. If you car is auto...DONT, i mean DONT cheap out on an exhuast. I got a Xforce thing, its droney as hell and i HATE it...hence got this one

I'm just going to use one of SMB's 4" cats and Mufflers and make up the rest of the exhaust myself. Their website does make mention of a skyline catback comming soon though. My old man has their 4" turbo back job on his XR6, its pretty nice.

well, ive been stung with my "quiet" exhaust

its a blitz, and it sure is quiet, but its retarding power like crazy

im looking to get rid of it if anyone is interested in a quiet exhaust and doesnt care for extra power

I had jack to from turbo back on my last 2 lines... cost me $880 on the r33....

Very high quality of work and will always take my cars there.... Its 40 minutes away but i will always go back....

I used a 3" system with split front pipe through a high flow cat and 4" out let... Got tested by Police @ 89db.... So it sounds great and performs well....

      Rear doors central locking wiring removed and cleaned. See the first 8sec video of when it’s filled with river silt. its a snip of what I’m up against. front and rear doors complete now. Maybe another day removing carpet and bits and pieces. Then the re assembly begins. 🤙 att.DqweJqhY5MZiZYQDVMhn3LtvdD1RBZ7TBG4f2s7W1zM.mp4 att.lFuN22MZEowqCbFAXoDw009r2gHL76ChMVfxMfBX-uk.mp4

      Dual exhaust questions

      By joshuaho96 · Posted

      There aren't boost creep issues, it's not engineered around the restriction of the cats but if you haven't tuned the engine a full decat + exhaust can flow enough air to run off the end of the OEM load scales and you will get a pretty substantial reduction in ignition timing as a result. I recommend using DFCO, avoiding ignition cut limiters, and avoiding popcorn tunes along with running a cat unless you enjoy a perpetually soot-covered and potentially burnt bumper.

      My R32 Money Pit & The Headaches That Come With It

      By 32.det · Posted

      Small update, it's been slow moving over the Christmas period with money having to go everywhere thats not my car 😅. I got myself a little present to myself from "santa" in the form of some tidy radiator mounts from fitmint automotive to get rid of the stock ones that look like they have been in an accident before and then straightened by a caveman. I know I should've replaced the rubber bush at the same time but I had no idea how bad they were until I was replacing the mounts. Decided to order their dash mat while I was at it as I feel like I am lucky enough to have a pretty decent condition dash and I don't want to risk it being ruined while it's parked in the aussie sun while I'm at work. I have found another electrical fault to add to the evergrowing list to eventually chase down. Every time I replace my taillight globe it blows within a day of use, I'm starting to think my life would be easier if I took a few minutes to learn how to use  a multimeter 😂.   Had some luck with finding a series 2 drivers headlight on marketplace to replace my mismatched series 1 headlight, a subtle difference but it's nice to have a matching set of lights now.   I returned to the air con problem due to being sick of this summer heat, found a good condition condenser to replace my leaking one! I got it in the car and was happy when I got the thumbs up that the system was now holding gas. Sadly the compressor is not kicking in for some reason, we even tried branching the relay in the fuse box. I have tried to do some research on the issue with no clear understanding of what the fix is, so for now it will be placed on the backburner until I can be bothered to look into the wiring to the compressor. The last small mods I have done was cutting the horizontal vents out of the front bar, not really in a functional airflow sense but I just think it looks better as I am not a fan of the series 2 bar. I also switched the shift knob out for a hosoboyo aluminium grex style one, it has a really nice more direct driving feel than the outdated rubbery oem one. Thirdly, I chucked on one of the ebay bonnet strut kits. The fitment is decent and they seem to work fairly well. They have only given out once while the car was parked facing downhill, I think if I was working under the bonnet I would still put the oem hood stay up to be precautionary as to avoid getting a speedy concussion.

      Got pneumonia, haven’t played with her in a while, but I’m back now. Previous owners cut bonnet pins into the bonnet. My choice try find a replacement or spend $15 get some pins myself to cover up. Now only one small hole to cover. looks shit now, but when the bonnet is red again. Be good 🤞

      R32 gtst speedo out by 10kph

      By GTSBoy · Posted

      No R32 GTSt had 15" wheels. 205/55-16 was standard GTSt fare. 4.36:1 is standard R32 turbo auto diff. I think the manual was too, not 4.11. 4.11 and 4.08 were R33 namual and auto respectively.
