I ordered this muffler from ibay. I would please like to know if this will muffle the sound better than what I have.

Here is the one I ordered,






I have the fart cannon cat back, you probably know which one I mean. I'm going to have this muffler welded in its place. What do you think?

 

It will be quieter. Not stock quiet especially because it is a zero chamber. What you have there is essentially a beautified glass pack.

Thanks brother. Now all I need to know is which end is the exit

 

It doesn't matter. Zero chamber center in center out. There is no designated in or out.

If it was a muffler with baffles then it would matter

I just got the muffler in the mail. It turns out though that one of the pipes is not 2.25" but more like 2.05". This is lame. What can i do to, cut the smaller pipe off and weld a bigger one? I am sure a muffler shop has everything to do that I was just expecting it to be 2.25" in and out. That's what it says.

I am trying to get the ebay seller to buy me pipe piece.

 

I had the muffler installed a while back. It helped the sound but its still too loud. No cat by the way just a test pipe. I was looking at this resonator/silencer to go in the place of my shitty ebay exhaust resonator. Would it make it more quiet if I have this welded to my setup?


Its not the cheapest but its not the most expensive. Its at the top of the list when I search "2.25 exhaust resonator". People are buying them though I I figure they're the best to make it quieter.

Should I use this as a replacement for the resonator that the ebay system has on there now or should I just add this one on there so i'll have 2 resonators?

I need it to be quietest as possible with no raspiness. Maybe the ebay resonator is bad and needs to be replaced cause the exhaust is raspy.

EDIT:

I just ordered this long one, someone told me that a very long one would quiet it down the most:

I dunno, how about you use something like, i dunno, like, uhhh, a real muffler?

 

x2 use a real muffler and a resonator in place of the cat, if you feel it necessary to run without a cat.

Been gone a month and it seems as though not much has changed...... If you want to change the size of the muffler tips ten you obviously have to cut the tip off and weld a new on in.... or use an cheap adapter..... I'm guessing you actually answered your own question when you mentioned a muffler shop..... take it to them and tell them what you want.

I'm out for another month!

 

I do have a real muffler on it right now but even with that its still kinda loud hehe. Its the stock Ex/Se muffler with a stock resonator/midpipe, but with no cat its still pretty loud. Someone said putting in a very long resonator/muffler on my ebay system would reduce the buzz and tone and quiet it down.



This is the long one I ordered. Magnaflow makes good stuff so I think this should do me well.





And about having a "real muffler" why would I want that, backpressure only lags the exhaust more and makes chokes the engine.



The long resonator/muffler is going to be put int he place of the waspy resonator from the ebay kit. That whole section on the bottom is almost going to be all resonator. Plus i'll be removing that crappy resonator that's in it already.

 

Real muffler you mean so that I can increase my performance by allowing more backpressure? Dude that's sounds totally rad!

Seriously though don't most people on here run cat back exhausts without real mufflers on them? By real muffler what do you mean anyways, the stock joint? I already have that and its still not that quiet.

I always thought that the turbo muffler I bought was a "real muffler". now i'm confused. Just cause its a straight through doesn't mean its not a muffler.

 

I consider straight through designs more like a resonator than a muffler. Yes it still muffles sound just not as effectively as a chambered muffler.

If you're worried about flow restriction use a muffler with inlet and outlet diameters and a case volume that is larger... if it flows enough it will not be a restriction. and no smart ***, adding back pressure is not what you are looking for.

See this is why I still consider you a troll. You know enough to find the answers on your own. Yet you still come on here and ask dumb questions and then start questioning every bit of information you are given.

Running a stock muffler with no cat and no resonator will be loud as ****. Every piece of exhaust that you remove, that has sound canceling or removal integrated into it, will cause your exhaust to be louder. I.E. your cat and the resonator...even though the cat is not considered a muffler or resonator...it still removes some of the noise. Obviously!

You need an actual resonator in place of that test pipe or a larger resonator inline that will cut down on the upstream frequencies/exhaust noise. Then your stock muffler won't be as loud....

 

Muffler shops have a tube expander in which they can enlarge the diameter to make it fit.

 

I'll share with you this advice I got from here a long time ago.

WS2=done. At the time, I didn't have the $$$ for it. So I did magnaflow this and that, and resonator this and that. I just wasn't happy and end up spending almost the same amount. So in the end, it's like I spent 2X the $$$.

My current car have no cat, and a Greddy SE. Yes, that cost money, but honestly, it's exactly how you would want it.

So my advice is, cut your losses now, or live with what you got. You can add a resonator. But I going to bet you are not going to be happy with it.

Learn from my mistakes...

 

I just read on a chevy forum that you can fit a muffler off a 90's camaro onto an accord! You should give it a try at least 10 hp+ gain!

 

That's not JDM. WE ONLY ALLOW MEGA TYTE JDM FLOW IN HERE.

 

You can tell its JDM VVV

 

That is so sweet dude, you did it to your car didn't you? Man let me know how it works out for you.

 

Dude man, I wasn't talking about removing a piece of pipe (resonator) but I was talking about adding a longer resonator in the place of the crappy ebay one that's already there.

Car's got a resonator and a stock muffler right now but its still loud cause it has not cat. I heard that the smaller the pipe the louder; but the bigger the pipe the deeper the sound. The extra long, quality resonator by magnaflow should make it better. I'll let you guys know and perhaps I will even upload a video of it. YAY!

 

IS THAT A TYPE R???

 

For telling us how much you know about cars in the last thread you sure ask some noobish questions.

 

Yes I had to hack up and put aluminum foil on the bumper so it fits and doesn't melt, but that's the price you pay for performance! I cheaped out by using clamps and JB weld instead of getting it welded, hopefully it holds up. I just got back from the dyno not too long ago, legit 7 whp gain! What a mean growl it has guys.

 

Acoustic filters are used throughout the intake and exhaust track of any given vehicle. Once one begins to change or remove these devices the audible output of a given engine will change, and sometimes it is not the most pleasant of tones.

On the subject of mufflers there are two basic types, absorptive and reactive.

Absorptive mufflers absorb the sound waves through a media surrounding a perforated tube encased in a larger tube/casing. Or more commonly referred to as a glass pack muffler. Usually straight through type design. Good high frequency sound absorption, but low frequency suffers. Reduced back pressure compared to a reactive type muffler, but tone/effectiveness may wear out due to absorbing media degrading or blowing out.

Reactive mufflers redirect sound waves in order to cancel each other out via multiple chambers. More commonly known as 'turbo' mufflers, they have better low frequency cancellation, but do not perform well at higher frequencies. Higher back pressure than absorptive type but are durable and less likely to blow out or change tone over time. FlowMaster mufflers are reactive type as they use reflection and redirection of sound waves to cancel out undesirable sound waves, this also gives FlowMaster mufflers a distinct sound.

Reflective mufflers are a form of reactive mufflers as they use chambers and redirecting walls to self cancel out unwanted sound waves. However, unlike typical reactive mufflers that do not use a straight through, reflective mufflers will often be of a straight through design with ports leading to chambers that are designed to cancel out sounds via reflecting the sound waves 180° to cancel out sounds. MagnaFlow have several straight through reactive type mufflers. Benefit of both types without the disadvantages.

Catalysts and diesel particulate filters are acoustic filters as well. Not originally intended to be, but are very good at canceling out or preventing unwanted sounds from passing from the exhaust. Removal of these devices tends to make an otherwise stock, or stock like, exhaust system rather raspy and/or resonate.

One other aspect of the exhaust system is vehicle type and where the exhaust exits. Shooting brake vehicles with dual exhaust that exit straight out the back will resonate pretty badly causing a drone inside the cabin. This can be remedied by either using turndowns, or exiting the exhaust behind the wheels. The rear cargo area would become coupled acoustically creating drone. Simplest solution would be to change exhaust exit location. With that said, prior to changing anything major in the exhaust system, temporarily add 90° bends(be it turndowns or piping) to the exhaust tip(s) and see if this changes how the exhaust sounds inside the cab.
