Ok i just got done with my swap about 1 week ago. Up until yesterday i was running open header, and of course vtec engagement was loud. Yesterday i had a greddy sp catback from a 96 prelude fitted onto my 92 four door. My question is why is my vtec not as loud as all other b16's? I am running a prelude stock intake with a aem filter on it. I mean you can here the vtec engage but its not like what other b16's with intake's sound like. Not as loud. It is almost as quit as a b16 with a stock air box. Any ideas on what is making it quiet? And i don't now if this matters,but it is a SiR II.

 

people have different mods so every car sounds different. dont worry about it, as long as its engaging then i wouldnt worry about how loud it is.

 

ludeSH, do you have any more pics of your 4dr? It looks clean as hell from the small avater pic, hehe.

 

 

Stock intake piping suposably lowers the noise, the sounds bounces of metal pieces better there for it's louder.

 

Yea thats what i was thinking, but it just seemed very quiet to me.

 

Have you got a pod filter fitted? The VTEC engagement screams if you do. Also if you don't have a pod and want big noise - remove the plastic piping attached to your airbox - it does get a little bit of cold air from under the bumper - BUT.... it's mostly for noise reduction - like a muffler. Even louder still - bore out the whole into your airbox - K&N filter panel replacements make it breath harder - almost as good as pod.
