Question: What's the sound difference between a round muffler and an oval muffler?


Answer: There is no difference in sound between the round or oval muffler. The only reason they are different shapes is for fitting reasons. One may fit better than the other.

Question: What sound difference will I get with a smaller muffler as opposed to a larger muffler?


Answer: A smaller muffler is going to give you a much louder sound than you would normally get with a larger muffler. The larger or longer the muffler, the less sound you will get. The smaller or shorter the muffler, the more sound you will get.

 

Sweet! Thats exactly what i was looking for!

 

1st question is wrong. A cannister muffler will make your car sound like ****. The N1 sounds like crap on max. The bigger the muffler the deeper/quieter/nicer the sound. Since cannisters are alway small they will sound bad...

 

I never knew that... interesting

 

Perhaps on an apexi muffler that is the case. I was quoting about magnaflow though. They use the same amount of filling in a oval as they do a round......even spoke with them on the phone about it. Length is the key to the sound..not the width........

 

My apex'i dunk sounds like stock but no one believes me . I guess size really doesn't matter sometimes.

 

it comes down to how much of the muffler itself is resonating material. If you look at an N1 muffler, its straight through design, with maybe an inch worth of resonating material all around inside, not to mention the size of the tips. Typical canister style mufflers like the N1, will be very loud, because the material inside does a rather poor job of muffling the sound, a type like the Dunk or Greddy EVO, would do a little better because theres just more stuff inside to muffle it, but then you still have giant tips that make it loud. A muffler that is a stock size, straight through design with moderately sized tips, would sound deeper and more rumbly than stock, but not to the extent of a straight through canister with a 4in tip.

 

well now that we are on this topic, anyone know of any mufflers that will give u better breathing than stock and a little louder but closest to stock?

 

the tip doesn't do anything to the sound. the tip is just for cosmetic purposes. like you say, the internal design of the muffler affects the tone, such as the amount of absorbing material.

 

I should have been more clear, sorry, I meant the size of the outlet itself. It won't affect the dB as much as actually adding more resonating material inside the muffler, but a 4in outlet is louder than a 2in outlet, given the same muffler.

 

there are many many options, and a search will give you the most info. but i'm still a strong proponent of the flowmaster 50 series. it sounds perfect on the maxima. little louder, little meaner, fills in the sound of the engine, but almost no drone and you can't really hear it unless you want to.

 

Ok,then hack the tip off your muffler and tell me it sounds the same....

 

i don't see how though. like on my muffler, the tip is 4 inches wide, yet the internal pipe where the exhaust exits is 2.5". so even if my tip was 3 inches, won't the sound exiting that pipe be the same?

 

No. I don't know how it works. There is a 2k2 max a block away and he has a 2.5-3" chrome tip welded to the stock muffler. The car sounds like a fart can civic, all because of a tip...

 

wierd. the stock muffler should muffle most of exhaust noise so it should remain fairly quiet, even with a tip....

i don't know

 

I would say that tips do make a difference in tone/ loudness... When i first put in my Stillen y-pipe and ran it with my stock exhaust. It was quiet with a slightly deeper tone, then i decided to cut the muffler output pipe shorter and then welded on a 4" tip and it made my exhaust louder making the deeper tone more noticeable. It's just like holding up a safety cone to your mouth and start talking, it somehow ampflies the sound coming out.
