Exhaust Cutout? Good idea?

Myspeed12 said:
cause on the switch theres already a mount that is connected to the switch on speedbeaver it looks like he just drilled a whole and put the switch through their. theres a link below, when you look at the picture theres a swtich, and the black thing im reffering to is what its placed on.

I understand now, that is the actual switch you are refering to, the trigger for the switch is the lever coming off the black box, the lever is the part you actaully move to open and close teh switch. I assume that the black box of teh switch is behind the blank, beaver drilled a hole through the blank, then there is a small nut that comes off around the lever and you twist it off, put the lever through the backside and coming into the cabin, then you spin that nut back down and it holds the switch in place. Unless it uses some other type of system, I have seen switches like that for fogs and what not.
 
Here is my switch:

I will need to work on getting my video back up from home later today.

i see so basically just drilling a hole so the switch can fit in
as far as I can tell from the pictures. Speedbeaver, any comment?

Yes, just drill a hole.

Personally I didn't even used a drill. If you go too quickly with a drill you'll end up breaking the plastic. What I used was an electric welder with a really sharp tip. So I melted the hole and the plastic didn't broke in multiple peices.

Then you just have to put the switch on, through the back, and screw the nut on the front.


Tip: do that in a well ventilated place... the fumes can get to you really quick and make you dizzy.... (stoned)

so they are a good idea? and what was that about it hurting your turbo? i want to get one and i was wondering where to put it? and is it a good buy?

What I did on my car:

I took the stock midpipe out and I had a new one custom made.
I replaced the cat closest to the downpipe by the exhaust cutout and the second one by a high-flow cat. I also putted non-foulers on the oxygen sensor so I don't get a CEL.

Result: closed - I sound bone stock. opened - well, you heard what it sounded like in the video above (glare)

And hurting the turbo??? First time I heard of it. The only thing that you might get is maybe 0.5 to 1.0 psi more boost when opened due to the backpressure loss. Just be sure not to spike above 9.5psi to be safe and you won't have any troubble.

You might also notice that the torque is slightly less in the lower rpms but there is going to be significant increase in the higher rpm range. Also, instant spool when you hit the throttle in 2nd gear.

To me It's only positive: all of the advantages of a downpipe-back, whithout the drawbacks of getting tickets for a loud exhaust. And of course, you could get everything done for about $300-$350 (if you put in a high-flow cat) vs $750+ for a downpipe-back.
 
speedbeaver do you think you can help me out with the electrical part, how did you wire it from the cutout to the switch?

What I did: I tapped into the fog light harness. Maybe that wasn't the best idea because for the switch to have current, the headlight switch need to be turned on and the dimmer need to be at zero (when I tested the juice I unplugged the dimmer switch so I didn't realized that it would be less than 12v if that switch was on).

Honestly, if I had to redo it all over, I would find another STABLE source to tap into. But on the plus side: when I go to the dealer I'm not worried that the mechanics will play with the cutout since they won't know how to get the juice to it.


Volcifero probably found a more reliable current source than I did.

is their any other sources that it can connect to?
ignition, no problems there and I have my cut out and turbo timer off it. I'll post up a pic tomorrow and a video of the cutout.
 
Myspeed12 said:
but at night would the dimmer stay bright or will it turn off?
You can manually ajust the dimmer. That's not a problem.

But if I had to redo it, I'd use the ignition wires.
 
ok...so ill just use the ignition wires...velocifero said he'll post up some pics on how to do this
 
I just drove a car last night with a 3" electronic cutout and it wasn't at all loud. T3, 11-12psi, fast as hell, and much quieter than my Racing beat catback + mam catted midpipe + ractive header protege. He has the stock exhaust hooked up to the other side of the cutout so um yeah with it closed it's at least 60whp power loss but it's nearly silent at full throttle and still much faster than my protege. I was shocked at how much a turbo quiets things down.

yeah, its raining pretty hard here right now, so I can't take the pics here at work, but when I get home for sure.

What kind of car?
