Ok so here i what I have..

b16a

I have a 5zigen fireball axle back that I need to keep on..(Gift from 5zigen)
2.5 inch piping crush bent from cat back.. not on yet needs rear flange

So whats the quietest resonator out there?

 

Just get the longest resonator you can fit in the midpipe. It is still going to be loud because of the large piping and the straight thru muffler.

 

Any long resonator that is 20" or longer. Magnaflow makes some good ones, or you can get those cheap hi flow Cats (with no catalysts in them)

 

The quietest resonator would be the biggest baddest sucker you can find.....relative. You won't get quiet but you will get low.

Have you ever seen one of the 20"+ in SS for 2.5" diameter?

 

no haha, i was just jumping on the bandwagon =\

my buddy has an hks, it comes thro 2.1/2, and then comes out to the tip as a little small exhaust, gives that sleeper look and is pretty quite.

 

I know you probably don't want to dish out money like this but the hks is super quiet. I have one and its cool but I doubt it free up any power.

 

greddy SP2 is THE quitest. I run mine NO cat and its still the quietest I have heard on an EF. $500 shippped off ebay

 

Seems like I post this up every day

My setup

Magnaflow muffler
20 resonator from jegs

And it will sound something like this

They don't make it....only the 14" comes in stainless.

 

I just put a stock Si exhaust on my 90 hatch and I love it!! I have been thru 3 exhaust systems in the last year....each one was too loud for my taste. I did notice a power loss of probably 10HP, yes 10 HP.....it is that bad. However, I love how quite it is.....

I will be switching to a RSR exmag soon, hopefully that will be the last exhaust I buy for this car.

 

rsr or hks.......my money will be going to one of those 2.....with do ya'll think is better for a d15, gonna keep it stock

 

I have had an HKS and yeah I loved it..


this is what I have now... looks like I just need a 20' resontator..

I did not see any at Jeg's...

thanks..

 

i just got a tanabe exhaust. full stainless steel, double walled. looks nice (kinda like a thermal). it was a test item, not sure if its the same of their current lineup. but man, its absolutely SILENT. its not like their fart sticks at all. so quiet, and slight rumble. no tinny or raspy sounds. under 4500rpm, i cant even hear it over the intake, which is also completely stock. it also dynoed at 107hp. all of this is with a gutted cat.

not even sure if this is even relevent to the thread, just thought id share... heh.

btw, i want to get rid of it. but not for cheap. its too nice looking for my car, im trying to be low key. i still have my stock which was fine for me. and it has the cat. i dont care for the smell anymore, so i need to replace the gutted cat.

 

is it the racing medallion version (prototype) tyson?

 

^^^i don't think the racing version is quiet at all if i remember correctly.

 

he said he has to keep his 5zigen b/c it was a gift from them he just needs a way to quiet it down..

opps sorry...i meant to put super medalion hyper...

 

RS-R Ex Mag is really quiet. I have it on my b16 rex and until 5k rpm it sounds completely like an oem exhaust system

morons

 

There is no real way to quiet down your exhaust cept get a better muffler (non straight through or keep it stock)

Resonators lower the pitch down (from the annoying angry bumble bee sounds to low, deep, your ear starts bleeding bass). The larger the resonator, the lower the frequences of the sound coming out of the exhaust.

I put the SP2 on my 88si w/o cat and w/ header and I thought it was insanely loud!!!! It's a great tone though.
-so-
I found a factory resonator from a late model Jetta and put it in place of the resonator that came with the Greddy and it sounds BEAUTIFUL!!!! and the Jetta resonator is 2.25" so it's not restricting the flow (not enough to make a noticable differance on an internally stock A6 anyway)

I'm gonna have to dissagree with that statement based on my experiances. My work is next door to a muffler shop so I get to hear a lot of before/after situations and replacing the resonator with a bigger / better one definately quiets the system down.

 

I guess it might to our ears. In reality, our ears can't hear the low frequences it is pushing out...hence we hear a quieter note.
