Has anyone decided to do this on there car yet? I'm actually planning on doing this at the same time as my headers. Any feedback on this?

 

yes... ITS LOUD.....

 

I would love this! was thinking about a pneumatic cutout (like the intake flap) which would be AWESOME because I'm planning on going w/ headers & stock exhaust

edit:
forgot to mention that my only concern is venting the hot exhaust gas under the car at speed. . .

 

That shouldn't be an issue...there's a company called "DMH" that sells them...but i'm contemplating as to where to cut it.

 

^^ Not much room.. BUT my guess would be two E cutouts after the O2 sensors..

Man its going to be silly LOUD with dumps & headers...!!!!!


Here is the OEM mid section..



Here is the PTS-JoeZ X-pipe...

This was done looooong time ago, like 2 years ago, and I believe it was posted here in CL. Link to the video:

Wouldn't the car perform worse since the computer isnt expecting anything different every time the cutout opens?

 

I don't know how it is with this car...but what happens is it basically bypasses the muffler (hence why it's so loud)...I'm gonna take Joe-z's advice and do it after the o2 sensor...should be no problems that way.

 

yo let me know where your getting the work done.. I want to do this for my IS as well..

 

Well I'm gonna have a buddy of mine...(pm me for information on him) do the cutting and welding. As far as the wiring goes...I'm going to wire it myself. I'm gonna run the wiring by the change holder and put the switch in there.

 

^^ Is this more for power gains or sound gains ??

Because honestly with headers, the exhaust & intake.. you will be putting doing approx 400 Rwhp already.. And its going to sound sick with the headers!!
