Ive been searching this forum for some advice on exhaust width.

Ive heard from 2 to 3 inches.

There's a Nismo exhaust for the 1.6 Juke at 75mm(2.9~ inches)
Is that what's optimal for a Versa HR16DE?

Didnt consider the turbo.

so 2"-2.5" is what ill go with. Ill have borla muffler at the end. maybe itll clean up sound from straight pipe.

i got a 2.25" pipe with borla 3".

sounds crazy. Mechanic made hole for sensor to at least fit and ive been driving all day waiting for my CEL to show up. hasnt yet. will come.

Next up coilovers or whatever suspension.

But im pretty paranoid with it now being pulled over because it's obviously straight piped with the sound.

So you eliminated the cats too? That will add some noise as well since the cats kind of act like baffling/resonators. You must have a shitload of drone. How's the powerband? Feel any low end loss?

Yes straight from the headers to the muffler. Im going to have the same guy weld a resonator, since pep boys doesnt carry smaller than 2.5".

Yea too much drone. I have a headache driving around all day. So many saves today switching to neutral to avoid attention.

To be honest, the acceleration seems slower. it probably is. but at high rpms, it walks like all the cars are still. I used to feel like the car had good acceleration until 5k rpm @ 100mph. today i went at 120 at 5K and I couldve gone further.

It also could just be that its an illusion being that im not used to driving something loud at low speeds.

but anyways, sounds gotta go.

Yeah straight pipe draws too much attention. It would be fine if the car is fast, but it just makes it sound like a ricer unfortunately.

I can't believe the sound this thing makes. Its too deep. With a 98 civic I slapped a aem intake kit with k&n and one time someone at the end of the freeway said they thought they heard a lambo. Lol, everything else was stock.

but that's the same sound my versa has now. As I'm writing this the resonator is being installed. So I'm just waiting what for what type of change this is going to do.

I hear you. I have a 1.6 with 2.25in. custom pipping. I had an eBay muffler on it and it was way too loud for my taste. At first it was fun but got very boring after a while, got a ticket for it as well so I had a resonator added and replaced the muffler. :thumbsup:

It is obnoxious. Like I said before, I start very slow around cops and they know I'm trying to hide it. Haven't gotten a ticket this weekend.

I like the general sound the system makes. 10 minutes from now I should be heading to work so I'll just post the result later for those who want to just get an idea of the system.

I'd go 2" on the 1.6 non-turbo. I run 2.5" on my Audi 1.8T, more than that and you can really start to feel the low end loss.

I have the DC Sports system on my V, which is a 2" with canister muffler. nice setup, no real low end loss, definite bonus on the high end. It was cheap, looks nice, and works. There is a bit of drone, but nothing too bad unless you're running the A/C and cruising at 80mph. VersaSpeed also offers a silencer that fits into the exhaust tip, and really quiets the system down. You lose some benefit from the open exhaust, but you get a much quieter ride and nice deep tone.

There is a serious restriction on the header. At the collector, where the 4 goes into 1, the pipe diameter is severely choked, before opening back up for the flange. So any gain you get from opening the exhaust is going to be tempered by the restrictive header.

seems right(what you're saying). I just went with some head math with other setups and other advice and decided on 2.25". The resonator was added earlier today. I started up the car and you can still quickly know its modified. But not extremely loud as it used to be. I'm glad its been added.

as far as I know for my engine there aren't much performance parts for it like headers.

I have an HR16 OBX 4-2-1 header i may let go...

I have 2014 1.6l just to check

 

[ram0042]

That's why i'd like to get the HR16 header working on my MR... there is a fabricating shop around here that could probably make me up an MR18 flange with the proper spacing, then heat and bend the primaries to where they're supposed to be. The primaries are the same diameter as the MR18 header so there won't be a restriction there.

is there a link so I can get a performance header for hr16de?

Product Name - OBX Racing Sports


This is for the 1st generation body, if the tunnel has changed much in the new (and more compact) Note, it may not fit properly.

They upped the price not too long ago, i got mine for the original $195.

Thanks. I'll play it safe and wait. im satisfied with my current exhaust system. and I dont know why but today i actually felt further improvement since monday. As if my gear ratios have switched. This is the improvement I was looking for.

That's what modern adaptive engine management does... adapt! For best performance and emissions.

Yea. Right on.
