Getting a 3" Split Dump, Hi Flow Cat and 3" Catback with 4" or 5" Output/Muffler.....its stainless steel aswell if that has any effect....

Will this system be overly loud or does it depend on who makes the system?

I cant see how one from Kakimoto or HKS or X Force or whatever can be any louder when they are the exact same size etc.....

So can anyone let me know or answer my question/query and thought....

Cheers

Matt

I have a full 3" system on my 34 and it is legal db.... Its really quiet :P

In reality that question cannot be answered because there are quite a few different muffler designs (internal design) out there...

I run a 3.5" to the cat. 3" inch cat, 3" resonator and 3" rear muffler with twin 2" outlets

plus a 2 1/4" screamer** pipe off external gate going into a 2 1/4" straight through centre chamber muffler which dumps under the car just behind gear box...

**I call it a 'moaner pipe'... :P

Its very legal db until waste gate opens and then would be just slightly over but sounds like a V12...

It really depends on what brand and design of muffler and resonator you use...

noise will depend on things like wall thickness of metal aswell as type of metal. Different mufflers have differnt internal designes which will either muffle more or less than others. Best to go with high quality mufflers as they usually flow better and muffle more

I think the cat is important too. Something cheap and restrictive (like my current cat :thumbsup: ) keeps it quiet. My mate has an X-Force turbo back exhaust and in the passenger seat (above the cat) it sounds like an aeroplane.

My guess is the cat really affects the tone because it's the first restriction from the turbo.

Look into a quality (metal) cat is my 2c

My R33 N/A 4 door series one sounds great.

Great general driving sound, no drone, and when the foot hits the floor its sounds crisp and strong.....lovin it!!

Ohhhh setup was conpleted at AAA Exhaust in Adelaide

2 1/4 inch from cat back to a 6" cannon muffler

Quiet often a stock exhaust sounds way better than the drony piece of shit tin cans that some bolt on.

I laugh every time I see some NA lancer or Mirage or Corolla or even a NA skyline/supra with a shitty canon up its arse.. they sound so loud and crap its embarassing and annoying.

Yeah canon mufflers suck... they are droiny and annoying.

I am seeing alot of cars with twin canon muffler set up... less noisy.

Any pics mate?

I've been looking like mad for a twin pipe system...

As far as I can tell, no one makes such a system for Skylines...

Even just a twin muffler trick, I've not found a thing...

But they are for 200sx. I havent seen one for Skylines either unles its a custom job... been to Newcastle recently and saw many Skylines there with this set up.

If by chance you are buying an HKS system such as Silent Hi Power it should be fine. I can't recommend it high enough. I have it on my R34GTT and it is quiet at idle and has a beautiful note and volume under decent load.

Sorry, have no idea about twin systems for Skyrines.

Cheers.

    • Update time!  The JZX110 had some maintenance needing to be done, so a lot of the seals with replaced to fix some oil leaks. Also used this opportunity to whack on a front mount that I'd bought some time ago.  I also finally got the rear lip painted and fitted.  I then got the exhaust done. It's just a catback for now. Custom made 3" stainless with a turn down. I could have a tip coming out, but it will require cutting the rear lip and possibly the bumper itself. So far I do like and it's made the car a little more zippy.  Close out with some nice pictures of the cars and a sneak peek of what's next.

    • Edit: It's now known as "R Performance" and is still in operation.
    • This lady loved her FD for 25 years!  https://www.topspeed.com/80-year-old-woman-donates-fd-rx-7-mazda/ My brother in law. He's nice enough to let me drive it whenever. He'll likely not see this, but I'll try: @r-is-for-fun got any pics?
    • Just something I found searching for more info on Emotion R, apparently the ECR33 Skyline GTS25t was either originally black, or there were two of them, the black one being the original demo car, then building a white one which was part of the 1997-onwards (to at least 2008!) Cockpit Tatebayashi Tokyo Auto Salon booth demo cars. It appears that Emotion R closed down in 2008 and was declared bankrupt in 2010: http://bank-db.com/hasan/208365. Scan of a magazine with the black R33 from 1996: Wayback machine archived page from May, 2000: https://web.archive.org/web/20000529061027/http://www.emotion-r.co.jp/skyline.html Option magazine with a few photos from the Cockpit Tatebayashi booth at the Auto Salon from various years: 2002: http://www.jdm-option.com/photo/index.php?action=item&category_id=154&image_id=3507 2003: http://www.jdm-option.com/photo/index.php?action=item&category_id=137&image_id=3033 2005: http://www.jdm-option.com/photo/index.php?action=item&category_id=116&image_id=1831 In 2008 Cusco website mentions that the Cockpit Tatebayashi ECR33 was displayed at that year's Tokyo Auto Salon: https://www.cusco.co.jp/event/2008/12/post_735.html As of 2021 it appears that the ECR33 demo car ended up being exported to Florida, USA: https://rmcmiami.com/inventory/1996-nissan-skyline-r33-cockpit-tatebayashi-demo-car-big-te06-turbo-endless-brakes-lsd-450hp/ And finally here's Google streetview of the Emorion R garage in 2023 which is amazingly not only still there, but the showroom is still full of various parts in stock and funishings, etc.: https://maps.app.goo.gl/ttyEAZdZLyzermyT9 Apologies for nerding out a bit.
