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.
