Z Car Parts.com -- Motorsport Auto -- Home. They have a cold air kit for the 280zx. You can easily make one yourself by buying a mandrel bent 90 degree tube and a K&N filter. There's no one who makes a dual exhaust, unless you meant a dual tip exhaust. HKS used to, but that system is rare and hard to find now. Otherwise, just use the one that's available from the mentioned website. It's a direct bolt on kit and doesn't cost much.

so you cant run duals off the headers??? PACESETTER 1970-1976 DATSUN Nissan 240Z 260Z 280Z Exhaust Headers 70-1037 | eBay like these you can just drop the y and run duals?

Why would you want to run dual exhaust on a L6? All you would be doing is adding weight and money for no reason.

Kerias

your dropping out cast iron and putting in steel pipe much lighter probably about the same with the amount of steel as for money i dont see that its wasted there is still back pressure on the cylinders it may not be as "much" power but your still going to gain some but mainly 3 cylinders open pipe headers sound ****ing wicked, unique and badass.... this also depends on the compression ratio your running too.

You're gonna get better peformance with a single exhaust.....

hoov100

I think he is talking about a divorced header?

FricFrac

Even with a divorced header you probably won't get the same draw with the pulses. The only time I could see using a dual exhaust on an L28 would be on a twin turbo setup.

Kerias

what about a h pipe set up? it would suffice the need for the pulses to be connected and give you that nasty rumble?

NismoPick

I gather from this thread that the Japanese L28 is the same thing as American V8's...

Where are you going to run the second pipe? I'd be afraid to have it one the passenger side by the filler hose. 2 out the same side looks weird IMO.

NismoPick

They made "Twice Pipes" for the S30. Snw installed a set on his grey S30 (pics if you search his thread).

It was a retro - 70's thing... not really meant for the S130 body style.

Kerias

in actuality im planning on running side pipes it flows with the body really well i was just wondering if it was possible to actually run duals or if i was stuck y'ing it off... im a custom fabricator so i dick with ideas all the time... i tend to lean to uniqueness when i come up with ideas

^^^ Anything is possible with the right amount of time, money, and skills.

It's your car, so do what YOU want to it. The common use of "dual exhaust" is for V engines that have two banks. Since the I6 engine just has one bank, there's not much reason for dual exhaust (especially at the tail pipe).

With that header, fab up a Y, and run 2.5" back.

ZZzzz

just dont get the msa muffler. huge disappointment. it is the angry bees in a can sound that i hate so much.

Kerias

my exhaust plans: run a decent set of headers preferably a deep throaty kind into a cat (inspection) then into a super 44 (1 in 2 out) and run side pipes should like a twisted bitch with anger issues!! and suggestions on headers? would extending them give a more throaty sound? would to stock cat work or will it dampen the noise too much?

FricFrac

I posted my exhaust youtube link on the main forum. It's plenty throaty....
