I currently have a nismo ypipe and a magnaflow x-pipe muffler new in boxes. I plan on cutting the "y" portion of the ypipe off and using it just as two separate pipes to start my custom part. I have decided to use my magnaflow x-pipe muffler at some point in the project, along with Vibrant products. I can not decide whether to put two vibrant resonators, then the magnaflow xpipe, then the vibrant mufflers, or what. Also thought about using the magnaflow xpipe, then a vibrant xpipe muffler, then two resonators. Would having two crossover pieces have any pros or cons? Any ideas would be awesome, thanks!

Thanks for the drawling. Looks like a plan to me.
Resonators before mufflers of course.
Do you think that you might have too many mufflers?

 

x2!

 

Well, I have long-tube headers and must eliminate the rasp.

Also, I heard that you want to place the xpipe as close to the engine as possible. Is this true? If so, does anyone make a resonated xpipe? (not muffler)

 

A resonated test pipe is a muffler - it's hard to perforate an x-pipe and pack it without an enclosure

Magnaflow...that's your solution.

 

I would start this differently.

Go from duals into the muffled x-pipe, all the way back to the vibrant resonators. See how it sonds and works first. Maybe wait a good 1000 miles for everything to season.

If you need further sound tuning, add the 2nd set of resonators after the X.

Basically the same design as the Fast Intentions Intimidator system with different components.

Hey Wren why don't you just sell me the headers .

 

So you would go with the x-pipe muffler THEN resonators? What about the "resonators before mufflers, of course" comment? Is that simply wrong?

Whats the fundamental difference between them? I've never understood.

 

You have to realize that the muffled x-pipe, is basically an x-pipe and resonators in one unit - not so much of a muffler.

You can always add small resonators before it, in the S part of the front pipe turns, but likely not needed. You would add resonators between the center brace and the differential, just before the mufflers, if you need to add them at all. You will also risk more drone by adding them.

The comment is not wrong at all..you shape the tone the mufflers give you in the END with resonators UP FRONT. But you wont get too much help, and the resonated X is fantastic.

If you haven't heard the FI exhaust yet - go to www.fastintentions.com - and you'll get the idea.

Xpipe, resonators then another setup of resonators in the rear. If you can the cats then you will want to go with a larger body resonator.

A resonator is a muffler is a resonator. It depends where you use it. For the most part, a resonator is in the middle of the car and mufflers are in the rear. Another way is that the largest unit is the muffler. Each manufacture lables it different. Another way o flooking at it to is if it has chambers or tubes in it, its a muffler.

In otherwords, a resonator can be a muffler and a muffler can be a resonator depending on where its located in the vehicle and what OEM manufacture makes it.

For the most part, the smallerr straight through cylinders are resonators. I have however used them as mufflers too on my personal z that i had.

 

Resonators and mufflers are not the same.

Mufflers are designed to reflect and deflect pulses...resonators do not and cannot do that on their.

you don't use resonators 'as mufflers' on a car...you simply do not put mufflers on a car and only run resonators. This would be a sound tuned open pipe scenario. The flow restriction is VERY minimal, and so is the effectiveness of the sound tuning...the more you use, the slower the pulse, the quieter it can become. The more devices used in a system, meaning the more complex it is, the less efficient it will be, and the more prone it will be to drone.

so you would go with the magnaflow xpipe and then resonators... with no mufflers at all? won't that be extremely loud with long-tube headers?

 

Magnaflow X and then mufflers.

 

Resonators and mufflers are teh same persay. Its based on what the manufacture wants to call it. Look at the huge "resonator" in a charger which sits in the middle. Thats not straight through, it has baffles inside but they call it a resonator. I know what your trying to say, but im just telling you that its preference of the manufacture. Ive seen a resonator from a company and then they take the same res and weld a tip on it and call it a muffler.

 

OK - so it's not what I'm trying to say, it's about specific design of the device. If the device regulates flow and reflects or deflects pulse for sound tuning and performance, it is a 'muffler'. If it does not do that, it is a 'resonator'. Technically, any flow altering device is a muffler, including a CAT, however some have other specific purposes and are called other things, like a CAT or a resonator.

Definitions of resonator on the Web:

A small auxiliary muffler that assists the main muffler in reducing exhaust noise.
www.cdnauto.org/glossary/r.aspthe body of an instrument, or any device to which the vibrating column (eg, a string, air column, or membrane) is attached. The resonator acts like a filter on the harmonics of the vibrating column, so that some of the harmonics are amplified, some attenuated. The interaction of the source vibrating column and the resonator produces an instrument's characteristic timbre.

A small auxiliary muffler found on some vehicles that further reduces the noise of the escaping exhaust gases.

those parts of instruments which resonate or vibrate, thus enhancing the sound of the instrument, particularly the body of a guitar (an example of a resonator box)

A resonator is device or part that vibrates with and amplify waves.
