So this past week i got my new 3" DMH electronic exhaust cutouts from DMHperformance.com. And i have to say, for a $200.00 mod this thing is really cool!!! Basically it's a length of pipe (3" due to where i put mine, and i have the Nismo catback) with a piece of pipe coming out the side to "dump" the exhaust and bypass the muffler. And instead of having three wingnuts and a flange to remove, you just push a button and it opens up a tightly sealed butterfly valve and bypasses your exhaust!! And the great part is that you can vary how loud your exhaust is when ever you want!
There has been talk of raspiness and loss of backpressure before, but those people had bought two of the smaller ones and put them just after their cats. To hopefully overcome both i installed mine just before the last bend before the muffler, so the resonator would still offer some muffling and hold in some backpressure. And it worked!!!! It sounds incredible!!!! Imagine your stock exhaust note that we all love, amplified 4 times!!! And you can hear the cam lope nicely when excelerating now!!! (Only car i can think to compare it to is the Volkwagon R32s, which have a real clean rumble when excelerating) I have felt no loss of power, if anything i have gained a bit at higher RPMs. And since it's so close to the muffler, there is zero rasp!!!
I highly recomend this to someone who may have stock exhaust, and is just looking for a cheap cool way to add more volume, and doesn't want to spend big bucks on a whole new set up!! It does drone on the highway. But that's the beauty of it, cause in 2 seconds you can make it stock again!!

Pics. Just washed the car, that's why it looks wet.

 

climb under the car?

 

What was the install like? Looks like a cool mod

 

Just went to a trusted local muffler shop, showed them where i wanted it, and an hour later and $45 lighter it was in!! I installed the rocker switch myself the night before. It's a pigtailed wiring harness VERY professionaly made. One 12V switched source, and one to ground. Then just plug and play the button and the dump. I ran the cable through my shifter boot. (Flame on) And installed the button to the left of the hazard switch. Switch is very high quality. And it looks like it should be there.

 

can you post a link as to where you got i? I was thinking about something similar to this dont wanna drop 1k on exhaust but could use it louder sometimes thats a great idea. thanks for the post pics would def. be cool.

 

This would be perfect for you then!


DMHperformance.com super fast shipping too!

 

humm im tempted to order right now haha you gonna be able to get any soundclips of what it sounds like opened up? if not no biggie im prob gonna get it anyways just would help a bit.

 

I may take some tonite. Not sure how to upload em. You really need to hear it in person though. I'm sure, like always, my camera won't be able to really capture the true sound. And it'll prob be all distorted.

 

Pics up!

 

I had a feeling that one of our members would do this. Looks like a trick set-up. Nice work.

 

Thanks!!

 

looks good, just wish there was a clip.

 

Ok, i shot a real quick vid. I layed the camera on the ground in such a way you can't see the car. I know i suck. I didn't realize it till i got home. And for some reason it doesn't sound very loud. But trust me it is. Esp when you hear the echo off the trees!!! I don't know how to upload on here, so this is a link to my myspace page where the vid is. If anyone would be so kind as to load it on the forum, i'll send it to em!!

wow bro that sounds alot better then i honestly figured it would. Im def. gonna have to pick this up. I wonder how loud it would be with test pipes lol. thanks for sharing bro i think you just made me spend 200 bucks. You got the 199 dollar one correct? i just need the 2.5 inch for stock piping right?

 

Glad ya like! I'm not sure what the stock pipe size is. Ask around in the forum. 2 1/2" sounds right if you're putting it in the same place i have mine, but i'm not positive.

 

you need to make a video on how it sounds.

 

Did ya read the whole post??

 

Dyno sheet would help also!! haha
Cool mod!!

 

lol, i'm sorry, i dont know how i missed it.

 

so the whole purpose of this is to make more noise and pollute the environment, also decreasing any backpressure your system may produce therefore hurting any little performance you may think you was going to get from this. go you, thanks for showing everyone what not to do with their 350Z, personally i think it cheapens the car by making it sound like a honduh with a fart tip exhaust.
