Anyone fimiliar with exhaust sliencer?

I just got my Greddy Evo catback installed. I knew it's a louder catback, but I didn't expect it to be this loud.( I don't know if it's b/c it's a dual or not.) I'm considering adding a sliencer, but I can't find much information on it online.
Is anyone here fimilair with the sliencer?

First off, that's a great catback you got. I've always wanted that, just couldn't really afford it.

Yes I'm very familiar with the silencer, because I had one myself. I changed my catback too and it became very loud, much louder than I had thought. So I put the silencer in, and it greatly reduced the noise, but now it wasn't just loud, it had become loud and very crappy sounding. I showed it to some friends of mine who are experienced with cars and they said that it sounds cheap, like one of the cheap exhaust mods people do at junkyards. (They call it "Mexican" exhausts).

I'd say it's stupid to put it on. It sounds dumb, restricts exhaust flow, and just ruins the whole point of changing the catback.

Sound clip?

Already took it off.

Nono, of the Evo.

use glasspack to reduce the noise..use like 2 feet of it ..thats what i did

Where'd you get it and where'd you put it?

go to kragens or autozone and buy the cherry bomb glass pack...its a red long tube that varies in size...you should put it right after your cat converter...the longer the glasspack the more it'll reduce noise

does glasspack go on the outside of the piping?
will it give the exhaust a bad sound?

No, it's a glasspack muffler. Really just a resonator with fiberglass packed into it. The longer the resonator the quieter it gets, and to a point, lower in tone. I had a cherry bomber on my car for a while and took it off. But again, that replaced my muffler; it wasn't in addition to it.

So if you have bolt on cat-back, do you have to cut the pipe and weld the glasspack on?
So does it go between resonator and the muffler or does it directly replace the muffler?

I believe hes talking about in between the reso and the muffler. It'd be just like another reso...Im thinking of doing the same thing, except i have neither the reso or pre-muffler and its only loud and annoying on the inside..

it's going to be most effective upstream of the resonator.  I don't have experiance with silencers, but if I were to get one, I'd go with the ATS by Apexi.  http://www.nengun.com/apexi/active-tail-silencer

.... or you could sell the EVO mufflers and get SP2's

I've listened to them on YouTube before, and they sound about the same. Actually, the EVO2 sounded a bit quieter than the SP2.

I have an SP2, and love the sound.. On steady RPMs you barely even hear it, if at all; I mostly only hear it as I'm accellerating, and even still I have to gun it to really hear it. But tehn again, I've got an i4, not a v6 (waaaaaaaahhhhhhhhhhH!!!!).

The design of the EVO2 and the SP2 dictate that the EVO2 is louder ..... and is confirmed by users.  The flatter SP2 or WS2 muffler changes the airflow direction and turbulance more making it quieter.  The EVO2 is essentially a large resonator with slightly offset piping.  The EVO will give off a deeper tone.  Lower tones carry longer and have more sound power.
