Hi all,
maybe it's an idle talk, but I would like to reduce noise inside a car somehow (made by muffler). Especialy low frequences. Does anybody here experience with this? Thanks -------------------- No more replicas... This is evolution... This is SS-four :)

Those crazy civic drivers  , or you Could shove oranges in it(just kidding). Right now i can't think of any other ways besides getting a different muffler.

Lay another piece of carpet across the back of the car. And you can also get a silencer. I don't like putting my silencer in if I can help it, it hurts performance. But performance shouldn't be a problem for you with a custom cylinder head and regord block. I'd like to know more about that by the way.

1. resonator
2. dynomat or other sound deadening material Bulldog is right about the silencer. Its effective at noise reduction but reduces exhaust flow which is generally bad - especially for FI applications. I am putting a 36" mid-muffler on my car next week to reduce the noise of my 3" straight through exhaust. -------------------- QUOTE(lagos @ Jul 10, 2006 - 1:55 PM) [snapback]454118[/snapback] i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this. |

Like hold a camera 2 meters away from the tip of your exhaust and get us a comparison shot. I would love to here the difference the mid-muffler makes. |

I would like to put a mid-muffler as well cause the droning is killing me esp. on the highway! I got 2.5" piping with 2.5" dp and magnaflow muffler. Muffler is only 5'x8'x14".
Thinking off adding a 18" long 6" diameter mid muffler just like jgreening is doing. |
