Hey guys, did a little searching around and there isn't a whole lot of discussion on louvered exhaust so I'll go ahead and ask my question in a new thread. Anyone know any good louvered systems? I figured that the added backpressure would lower the note of the exhaust and give it a good growl that I'm looking for. That combined with a 5/16 spacer and MREV2 should sound pretty badass. Has anyone heard what a louvered exhaust sounds like on a Z?

 

What the hell is a louvered exhaust?

 

+1.

 

+2.......can you clarify as i am interested in what this is

 

+3????

 

Spiral louver core. That is the what it is called. It is older then perforated core. They were generally found in glass packs years ago. It riffles the exhaust out opposed to absorbing more of the sound like a perforated core would. Personally we have tried to get away from that because of many reasons. First, like I said they are louder and we have tried to quiet certain systems down. Second, we have found that they aren't so good at cutting rasp down, or out so we use the alternative....Tony

 

Sorry guys, here's some pictures:

Those bumps that you see here only go one way, so the air exiting can move fast, but the back pressure is increased therefore giving you more sound.

 

AHHHHH. Ok, then the answer is no.

 

Well I'll be damned.
