Exhaust Cutout? Good idea?

[chaos2015]

i know it defeats the purpose of having a cut-out but then what do you guys think there would be any benefits if you were to put it right after a catted mid-pipe. Would it be the same has having a j-pipe back exhaust on command with and electric cut-out?

i have a catless midpipe with a cutout running to the stock axleback, and i gained 10 whp on the dyno running it open. so yes is u have a restricive muffler

Another questions to those with cut-outs....Do you see a psi change common when installing just a 3' catback associated with the cut-out? I would think less backpressure would result in maybe a minute psi increase???

In a N/A car, backpressure is certainly something that needs to be considered. However, if you are turbo, the turbo is the biggest source of backpressure you will ever need! Think about it, the turbo itself would be a huge restriction if it wasn't giving back the extra power. How do you think some cars exhausts end right after the downpipe? So, you should not see any real difference in PSI, just a sigh of relief that your car can now breath like it was supposed to.

I just got my QTP, im excited to have this on, but Dont know how to set it up does anybody have an install guide or something.

depending on the size of the turbo and how close the cutout is to the turbo (i gess piping size would also be a factor), a cutout could do harm to a turbo. so sure there are advantages, but the turbo might be unhappy. a good rule is put the cutout as close to the firewall as possible if u have room. if u dont have room, then ehh... just put it where u have room.
heers somethin that sound like a good idea... maybe? http://www.sptimes.com/2005/09/28/Tampabay/Nitrogen_in_your_tire.shtml

my switch = crawling on the ground and taking off 3 wing-nuts... old scool it and get a cable operated! thats all 70`s.

is there any way to put next to the lighting adjustment on the left side of the steering wheel

thats the same switch i have(first)

Thanks YellowMsp... I was wondering if maybe te cat on say the vibrant would hold the turbo back a little?? I guess with a high flow exhaust the small restrictions due not matter if the trubo is flowing well enough... This mod is in my future for sure...

I put my switch in one of the blanks next to the dimmer

 

[Myspeed12]

yea velocifero, thats how i want my setup...how did you get it their? What does it took to have the swtich their?

12v source, drill, welds, and patience.

Here's mine:

I have a different style switch than Beaver, that is one reason I went with DMH for my cutout. mine is a flat rocker, so it sits pretty flush and isn't really that noticable. I'll snap a picture for you when I get home, or if you want to PM me your phone number and can receive pics from a tmobile phone I could take a pic on the phone and send it to you. For mine I took out the blank to work on it at a bench, cut the appropriate hole (dremmel or drill works easiest), installed the swtich into the blank then ran the wiring through the firewall and through the opening for the blank, connected the wire and switch, reinstalled the blank (just pushed it back in), ran the wire coming through the firewall to where the cutout would be, then since I don't have the tools or knowledge to weld I had a trustworthy exhaust shop here weld my cutout in place. WE actually decided to remove the highflow cat from my vibrant and install the cutout there, he put flanges on the cutout and on the removed cat so I can always drop the cutout off and rebolt the cat for emmisions or any other problem. It is definetely easy to do the wiring and switch yourself, but if you don't weld then get a good shop to do it.

ok mines is gonna look like speedbeaver most likely, so what 12v source did you use, and how did you get rid of the black looking things that is originally connected to the switch?

Ignition, same wire I used for my turbo timer, it is a blue wire that is left of the steering column, there are two red wires, I need to look at them to tell you which one I used. not sure of what you mean by the black thing originally connected to the switch?

Can yall repost your videos? I didn't get to see them.

 

[SpeedBeaver]

My friend was hosting them but it seems he removed them. I'm going to ask him tomorrow to send me a copy and I'll post them.

 

[Myspeed12]

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.

Ok, I found the fly-by video, I had to zip it so I can attach it.


Oh and, tunnels for the win! (first)

The camera car was actualy a 2001 mustang GT with a 3" catless, muffler-less exhaust so that gives you an idea of how loud the cutout can be.
