Performance Exhaust For Less

As much as I enjoy the quiet ride of my 2006 Murano, I really wanted a throatier, meaner sounding exhaust.

After reading the forums, I tried just removing the center muffler (which is just a resonator). That yielded a slightly louder exhaust that bordered on a rice burner sound. Definitely not a throaty mean sound.

Buying a $1000 Murano performance exhaust was out of the question. So I described the sound I wanted to my muffler guy and he suggested replacing the Murano muffler with a Flowmaster muffler for the V6 Camaro. My roommate happens to have a V6 Camaro, so I compared the two mufflers. Sure enough - the inlets and outlets are in the same place and the Camaro muffler is slightly smaller.

I had the Flowmaster Camaro muffler installed. Keep in mind, the center muffler was already removed. At idle, the Flowmaster exhaust had a nice deep rumble. But on acceleration, the noise was unbearable. So I went back to my muffler guy.

He put a 24" resonator where the original center muffler was located. The result... SUCCESS! The perfect exhaust sound!

Now the Murano idles silently from inside the car, and it has a barely audible low rumble outside the car. On acceleration, it lets out a sweet throaty growl. I love the sound of this car!

Total cost - about $350 installed.

Original look was preserved. The benefit of the smaller muffler is that - unlike the original muffler - it can't be seen from behind the car.

alright, now that this mod has been around for several months, i was wondering if anyone on the forum went a different route and put in a magnaflow rear muffler instead of a flowmaster. i'm thinking about going that route.

Quick Exhaust Fix

I finally got tired of seeing that mid-muffler hanging there in front of my snow-plow fuel shield. So, I went to the local Midas. Mr. Midas suggested that, with the ginormous muffler in the back, the middle muffler is likely unnecessary.

So, they took it out and welded-in a piece of straight pipe. I can hardly hear a difference in the exhaust sound (tone or volume). My wife didn't notice a difference either. I don't hear a rice-burner tone like Linky described when he removed his mid-muffler.

In addition to not having to see it, my MPG has gone up... from 16.9 to 18.5. That's with slightly-oversized Yokohama Geolandars..... I think the actual MPG number is about 5% higher due to the tire size...

So, overall I'm pretty happy with the outcome.

I appreciate everyone's willingness to share their experiences - thanks to all.

Yes I did, see page 5 of this thread, it is not loud but but a nice deep performance tone.
How does it sound? Similar to an FX or FM exhaust? I am debating which route to go as I get good prices on Magnaflow over Flowmaster but most people on this forum has gone with the Flowmaster.

Do you have a sound clip?

Re: MAGNAFLOW 14266

reddog said:
Well, I went ahead and did it, I installed a Magnaflow 14266 and 14865 in the center, muffler shop used 2.25 pipe, from the cat all the back. Sounds nice and deep, and is not much louder than factory installed. But my biggest fear with doing this is that my MPG would suffer, in fact it has gone to other side. I use to get 18-19 MPG, but now I get 22-23 in traffic, can not wait to make a road trip, great power and very good acceleration.

So I am very confused, here. Could someone who has much greater knowledge about this tell, or me or come up with an idea. As how heck this mod has got things so much better. Honestly I was after a deeper tone, and was willing the pay the price in lost MPG.:confused:
any sound clips?

Linky, you're the best! This is precisely what I want for my MO, and it's cheap too (only $100 on Amazon)! I think the stock exhaust tone sounds very empty and gutless. I want an exhaust tone that is subtle during normal driving, but has an aggressive growl when you punch it that matches its aggressive looks (not loud and/or ricey). This mod is strickly a sound enhancement, not intended for any performance gains (you would need to overhaul the entire exhaust system with a cold-air intake, headers, true dual exhaust and less sound dampers for significant gains...iow, stock car missing 2 cylinders!). I hope to have this done in the springtime!

Bambus, I appreciate your YouTube - Stock VS FlowMaster video comparing the stock muffler sound to the FlowMaster from both outside and inside the cabin. Well done sir!

On a side note, Linky, you still around?

I just got this done with the flowmaster 80 series in the back with a 40 series for the mid with 2.5 from the cats back and i would say that it sounds comparable to 350/fx/g35 with mild exhaust (75-80% sound match) thanks for the heads up linky!!! great job!

yeah, they're 4" oval, double roll, double wall stainless. total cost was around $400US. a majority of that was for the welding and piping (I ran 2.5" from the cat back) that part was $230.

Just put in the order for the FM! Under $100 with free shipping from Amazon! :7:

My mechanic said to make sure it was not a universal fit but 'true fit' or something to that affect. He basically said he doesn't have the equipment to bend pipes and such. Does anyone know if the FM needs any special piping work or if it's essentially "plug-and-play"?

Thanks,

Patrick

EDIT: This muffler needs custom piping to work. It cost $150 for the total install.

Anyone running a Magnaflow? If so, what is the model number? How does it sound compared to the posted Flowmaster clip?

Im asking because I get Magnaflow at cost pricing.

Sounds amazing!
I actually did mine too about 6 months ago and love it.
I have actually had 3 people ask me if I have a G35/37 exhaust when at a red light. :D
I did swap out the tips for a larger one too!



Just switched my stock out w flowmaster 80 series today. Sounds awesome!
