Performance Nissan has a new mid pipe for the sedan.

G35 Sedan High Flow Exhaust Mid-Pipe - $235.00

Installing this onto your G35 Sedan will get rid of the very LARGE restrictive resonator in your stock exhaust and replace it with this Higher Flowing resonator Piping.

Weighs less then the stock resonator piping and will add almost as much Horse Power as a full cat back system when used with a Y-Pipe. (dyno numbers soon to come).

Direct bolt on installation.
Currently shipping 2 weeks after purchase.

It is very similar to coupe mid-pipe. ^^; How about sound?

Jason,

If it is a coupe midpipe, will it fit the sedan without modifications?

Just a quick side question, is there a "Y" pipe that would fit the sedans?? I"ve seen them for the coupe but I believe we need a longer version. Also how bad is the stock "Y" pipe?

Sorry, their's really no point in intalling the coupe mid pipe as a performance mod. If your chasing power, that's not the way to do it. Their are way's to make power with exhaust system's, and their are way's to waste your money. You make power by either buying a proven engineered system, or you get a understanding of what make's for a more effecient system and ruthlessly apply that understanding, not giving in to any compromise on flow or effecientcy. And let's not forget you can buy the Borla true dual exhaust for the sedan for a price that isn't very different and will out power a Y-pipe/mid pipe combo. Plus the sedan's muffler is NOT a performance muffler, whereas the coupe and Z's muffler is.

1. I just examined my premuffler, it was removed from the car in such a way that you can actually see it's construction on the inside. Guess what, straight through. The pipe inside makes a lazy S turn 23" into the body and only at that point, to the end of it's 31" body length does the pipe have any perferation's in the pipe walls to absorb sound. The sedan premuffler actually cannot be painted as a performance costing device, even though I myself have felt it does, today's examination, say's otherwise. Now I understand why I did not feel a real differance in power when I removed the premuffler.


2. Both the Coupe and sedan oem pipes still have crush bends, granded they do not have any ripples in them, they still narrow the flow path. If you want more power and will be sticking with a Y-pipe that has a collector with the same collector flange diameter as the rest of the oem system (65mm or 2 1/2") buy this mid pipe and have a muffler shop spice in a short piece of pipe to make it fit. $189 and mandrel bends, plus it's stainless steel.

3. Any sedan owner can easily have their premuffler removed and replaced with any 4" round muffler as a resonator, this just like the coupe mid pipe will deepen the sedan's exhaust note in the lower RPM range (idle to 2.5K). COST,.......all of $70 installed.



4. The whole Y-pipe thing. The oem Y-pipe is awfull, take a look at these pics, taken with the heat sheids removed.






So, what's wrong with the oem Y-pipe that a good aftermarket Y-pipe would fix? Y-collector design, mandrel bends (look how seriously restricted the oem pipe is where it turn's out of the Y-collector, that's a really bad crush bend).

So who makes a good aftermarket Y-pipe, well hold on know, their's a catch. Remember how their are element's that will make a aftermarket Y-pipe better the the oem piece, things that improve flow. Keep that thought. Several of these aftermarket Y-pipes are ment to hook up with wider 80mm pipe diamter's downstream, thing is your oem system downstream is just 65mm. If you hook up a Y-pipe that has a 80mm flange to a 65mm flange, you will have create a 1/4" high road block(read turbulance) to all the flow improvement's that the Y-pipe is supposed to give. It's matters since exhaust gases tend to channel along the walls of the pipes, which is why mandrel bends are so important to flow, not just for maintaining full cross sectional width. Now, that is not to say you can't use a Y-pipe that has a 80mm collector. All you have to do is install a simple transition piece to your mid pipe that will smoothly go from 80mm down to 65mm. Only cost's around $22 and any muffler shop can make it happen.
Your doing all this for more power, don't get a better Y-pipe only to ignor the 80mm to 65mm issue, it makes no sense to ignor with such a easy fix. Here's where to buy the transition piece. http://store.summitracing.com/produc...earchtype=ecat

Of all the Y-pipe's I'd pin the Jic as the best, but it does have a 80mm collector. Notice that in this pic, it's mated to a 80mm system, no doubt a Jic itself.


After the Jic, it's get's kinda fuzzy, their's Fujitsubo/Nissmo Y-Pipe come's to mind. Then theirs a slew of design's that have nice straight piping, but do not have the greatest Y-collector design's.

Japtrix Y-pipe has 80mm collector

Ultimate-racing Y-pipe has 80mm collector, not really liking the flex sections butted up to after a bend.

Here's one Y-pipe that does have a 65mm collector, nice collector design, bends could be not as tight. Price isn't to bad either at $285. http://www.nfcmotorsports.com/a.html

G Sedan, excellent post. I knew the stock y-pipe was pretty bad but not that bad. Those pics you took of the naked y-pipe are eye opening. Getting any aftermarket y-pipe is probably better that thing. I have one question though. I'm interested in getting the nfc motorsports y-pipe. But I noticed there are no flex sections on that pipe. Would this be a concern as the engine is moving up and down? It looks like the JIC, the Ultimate Racing, and the Fujitsubo ones do have flex sections where as the Japtrix and the NFC doesn't.

JIC makes the best Y-Pipe IMHO... unfortunatly it is backordered for another 6-7 weeks...

I am all for custom mods...

the reason I am bringing this one up is for the simple fact that alot of people are not comfortable with getting pipes cut up...

one is a 4 bolt solution they can do on a couple of jack stands... the other... well... more is involved...

Theirs enough flex in the rubber isolation mounts on the entire exhaust system that IMO the lack of flex sections is a non issue. A undisclosed fact about most all flex sections is that they have awfull corrugated ridges inside them. BUT, if it does cause you concern you can simply buy a pair of short flex sections and add them in, another super easy thing for any muffler shop to do.

My system does not have flex sections, fact is I bought a pair as part of the parts build up to make my custom system. But when I opened the box and saw that they had nasty corrugations to disrupt flow, that ended any idea of using them. I have zero issues regarding not having flex sections in my Y-pipe.

Thanks for sharing your knowledge on the Gs exhaust. Your pictures make some of it look easy until I get to the payment part but thats another issue. Thanks Again!!!

Well said Jim. IMO, the information you've provided in this thread is right on the money.

Hi,
Any difference on performance?

 

yes, it fits with no modifications...
