Hello,

Just to let you guys know, i have posted a comparison video of OEM vs FLOW on You Tube. Just type "Murano Muffler" and it will come up. For N E 1 that is interested in the swap. I love mine. It just shows you, bigger isnt always better (muffler that is).

Great job on the video:claphead:

That was a great comparison. I do like the sound of the Flowmaster and also how neatly it tucks under the rear end.

Thanks!!

sounds great. reminded me of the infiniti SUV sound which I like also.

what do you think? do they sound the same?
It may sound pretty close but since the MO has a CVT tranny; the sound will not be the same as the car accelerates. The FX's sound goes through incriments of output as it "Shifts" through it's gears as the MO's sound is constant through it's speed increase.

You might be able to reproduce the shifting sound a little more by "manually" shifting through it's "gears" but I suspect that it will sound more linear......

Thank You

John,

I though because of the CVT it would be a lot different, but in fact you can still diffriantiate when it changes rpm, with the OEM you could not because it was so quiet, but with the flowmaster, its noticible and sweet.

Bambus;
Where did you have the work done? It looks like they did a great job:4:

The job is awesome and clean looking. I did it at a Stainless Steel Exhaust shop in my town. They do awosome custom jobs. Its not like the "Big Name" exhaust shops. They charge a lot and all they care about is getting it done, dont care how it looks.

I got some pics in my gallery of the Flow, but i dont have any OEM. If someone would post them, that would be another way to compare how the smaller size looks nicer.

Had a look in your gallery and the details look smoooooth:cool:

Where abouts are you located?

I also noticed your LED "inner" bulbs; where did you find those little jewels? I would love to get a set of those(I hope you don't mind:D ).....

John,

Im in Brantford, the lights are 194 LED bulbs, I got them from a local "performance shop"(approx $10 a pair). THey come in a variety of colours, I have blue, but there are white, yellow purple etc. I think blue is a nice accent, and it goes well with my blue bulb lights (non HID) all around. Its just a simple bulb swap. I rewired mine to turn on with the dayltime running lights so they come on with my fog lights. Since its a LED and it draws almost no power, there are no issues. I can get a pair for you if youd like if you are close. It would be cool to meet another MO owner.

Hey ANG

The Muffler is approx $150 and the work cost $200 to put on ($100 for parts and $100 for labour)c= $350 CAD. Just dont go to "Mufflerman" - one location quoted me $650 (because its a custom job) and another location told me "its a completely different muffler - IT CANNOT BE DONE".

Just go to a custome exhaust installer. They do a nice job.

How much does a system like that run for the MO? $$$ or CAD.
Got the FM 80 Series muffler for $92 on Amazon with FREE shipping! Arrived in less than a week even with Super Saving Shipping. The work cost $150 at Monroe Mufflers. The guy did a great job with the welding and kept the tail pipes in the OEM position. I love the sound!

Thanks again Bambus for the comparison video. Well done!

Hey McPatty and others

What kind of tips did you use on your install and where do you get them? I assume the Muffler shop fabricated the pipes that show on the rear of the MO and the one that connects to the rest of the exhaust? Did you have any problems connecting to rusty existing sections??? Also what was the part number of the FLowmaster you installed as many show the outputs on the same side unlike the OEM muffler. I could really use some guidance as my exhaust leaks at the flange and it is time to replace. :(

Flowmaster 42583 80 Series

njmo,

Flowmaster 42583 80 Series Cross-Flow 2.5" Inlet, 2.5" Dual Outlet Muffler

I kept it as simple as possible to both reduce cost and to keep a factory look.
I had the muffler shop cut off the factory tips and weld them onto the FM. The
tips connect to the muffler with 2 short pieces of custom pipe. The intake
connects to the FM with another short pipe. Since your flange is leaking, this
is going to cost you more since they need to replace more pipe. Cost of the
muffler (Amazon) was $92 with free Super Saving shipping. Cost of the job
was $150.

Shot from underneath. You obviously don't see this much of the muffler when
you're standing up. As you can see, the outlets are actually on different sides.
When the muffler arrives, it has an orange sticker clearly marking the inlet.

Image

The only custom pieces were the 3 small pieces
he used to connect the factory pipes to the FM.

I hope this helps,

Patrick

Thanks

Very cool using the existing tips and piping. I went ahead and ordered the Gibson muffler for the 06 & 07 Murano. I have a 05 and figure that my Muffler shop should be able to weld it on. The Gibson comes with the piping and new tips so I should only need one weld were the flange currently exist. That is where my exhaust failed.
Good luck with your setup-njmo

Got the Gibson Exhaust

Hey Mo Guys,
Just wanted to update the forum that I received the Gibson Muffler that is sold for the 06-07 Murano and had it installed on my 05 SE. The Muffler shop cut my old exhaust of just after the failed flange and created a custom pipe to make the connection. There was some adjustments needed to the hangers to get the new exhaust hanging level and straight. Total cost was $255 for the muffler shipped to my home and $85 for the install. Gibson includes tips with the MO muffler so I am a happy camper. Sound is a littler heavier than stock which was quoted at $674 by Midas.

All Muranos come from the factory with resonators. It's the muffler-looking thing in the middle of the exhaust system. It reduces the effects of exhaust pipe resonance, the obnoxious loud droning sound that happens at a particular engine speed. I left mine alone and would recommend you do the same. Some members swapped them out or removed them altogether and were unhappy with how loud and unrefined it became. You don't want the pipes vibrating and making noise.

This is the thread with all of the muffler swap details: http://www.nissanmurano.org/forums/72-performance/7442-performance-exhaust-less.html

You guys definitely tempted me! Shame on you!! lol. I received my FM 80 series yesterday and since I'm in NY for a couple of days, I figured I'd have it installed here. Went to a Monro Muffler shop in Valley Stream and the guy told me he couldn't do it and wouldn't even recommend doing the swap. I went to another shop (American Muffler) and the guy there (very nice guy!) was very professional and if I didn't have to leave tomorrow, I'd probably do it because he'd be able to do it tomorrow and if that wasn't enough, if ever I wasn't happy with the sound, he offered to convert back the OEM muffler. Now one minor concern, since the current muffler is stainless steel, rust was never a problem. However I noticed that the FM muffler is aluminum and in Montreal, winter can be harsh so what do you guys suggest as a good way to prevent rusting? I was thinking high temp paint maybe. I want to get this taken care of before installing it.

Don't worry about having to convert back to the OEM muffler, you won't want to once you hear the FM! I had the guy that installed mine use a high temp. black paint just as you suggested. He actually painted all the way to the exhaust tips, which really helps to hide the muffler from view. Used the same guy to install FMs on my camaro a few years ago, and the paint he used is still holding up well. Unless somebody throws out a better idea, the paint is a good option and will help hide the muffler.
