360 Exhaust Valves Plugged....and sounds GREAT

I did the same, also going into my challenge exhaust. Did you just plug the vacum line or did you disconnect the connector on the valve ? I ask because I had originally disconnected the wire harness on the valve, then I experimented reinstalling the connector and plugging up the vacum line and for some reason it sounds much louder, which enjoy more.

anybody chime in to correct my theory.

 

I don't think you will get a CEL with a 360 from plugging the valves. I think it's similar to the 430 but I could be wrong. With the 355 it definitely would set off a CEL if the valve was wired open.

If the sound gets too much for you, put in a remote valve controller like the one that BISEL sells here on Fchat. I installed one in my 430 and I love it. This thing is an absolute MUST in these cars!

My F430 came with the same "mod" done by the previous owner! It sounds great too!

Sometimes I'm curious what it would sound like stock... but I cant get myself too hook the lines back up!

 

Disconnecting the vacuum solenoid valves on the 360 is no problem at all. But, on the F430, if you disconnect the solenoid valves, you will get a DCT (Diagnostic Test Code), but not a CEL. At least I do not believe you will get a CEL.

The better solution is to disconnect the exhaust bypass valve vacuum hose and plug the end. The valves will remain open and no worries about the a CEL or a DCT.

Of course, you could install a controller and have the option of switching back and forth.

Buy the remote valve controller Bisel sells, it's great... I also notice a slight performance decrease when valves are open at normal slow driving... But it sure sounds better..

 

Yeah I should have been more specific... The vacuum hoses are disconnected and plugged on my 430 so no lights or issues!

 

As you have a 360, and all you did was disconnect the vacuum line to the bypass valves, I doubt that the CEL is related. Let us know what you discover when you read the code.

I agree. I just purchased a 2000 360 and it also has this mod done and I have not seen the check engine light and neither had the previous owner. I'm sure it has to do with something else that you better get checked out.

 

Installed Steve's bypass controller on my 430. Awsome sound and with the push of the button you are back to stock. Easy to install and no CEL problem. Buy it.

 

Glad to hear it! The way I did it while I wait for my in-line petcocks to arrive is to cut the vacuum line midway between the solenoid and the side panel, shove a 2" long 3/16" steel rod with a layer of electrical tape (thicker in the center) 1" deep into one end of the vacuum line, then shoved the other vacuum line over the other end. Good seal, secure, and ready for the petcock on/off switch when they get here..

 

3/16" petcock slightly too big, finally found 1/4" in line, should work perfectly. $25 mod and 30 seconds to go from open to closed.. With my Challenge exhaust it's pretty loud!

All in good jest ... no disrespecting your method ... but, you need to total the time to stop the car, open the door and get out, open the rear deck lid, close/open the valves on both sides, close the lid, get back in the car, close the door and get back to speed.

Actually, looks like a nice easy way to force the valves open or return them to ECU control.

If the pipes are pulled off and not plugged then it is possible that the ECU will throw a CEL due to a loss of vacuum in the system that operates the valves and stuff like the variable length inlet manifold, etc, etc.

Rather than plugging the pipes, I like to fold them over and hold the fold with a zip tie.

 

Steve, is this what it's come to, are we really that lazy?? LOL

 

LOL Gary ... hey, I remember when I had to get out of the chair and walk across the room to change the TV channel ... I thought I had died and gone to heaven when we got our first remote control ... and that remote had a long wire attached to it. My grandsons cannot even comprehend that one would even have to do anything so primitive as going across the room to do something like change the channel or volume.

Steve

 

Why not just unplug the electrical connectors?

 

Why not just purchase Steve's remote bypass valve controller? I can't tell you how easy it is to install. There is no way I'm going to pull the car over, open the engine lid, open a petcock or remove golf tee plugs before I come back to my development when I go out for a night cruise so I don't wake up my neighbors. Just press a button and PRESTO!! Just my $.02.

I agree with labman,a Steve's remote bypass valve controller or as mine came with a capristo remote controller.Nothing easier than a remote in your hand to open the valves and close.I have had mine for two years and never a light came on.

 

I'm not sure that big remote would mount well on the back of my CF engine panels...
