electronic exhaust cut-out

[Hussain]

ok so i finally got my electronic exhaust cut-out. i'll take pics and post em tomorrow. monday i'm going to the shop to get it installed and then tuesday morning me and my friend are going to run the wires and mount the switch (he already did it on his car). so hopefully by tuesday my car will be a beast lol i have 3" piping before the cat so i got a 3" exhaust cut-out and i'm going to mount it before the cat.

[Hussain]

ok so i went and got the piping cut and welded and had the cut-out installed. they told me $40 but charged me $60 cuz they had to add piping (they said usually $80 but gave it for $60). tomorrow morning i'm going to my friend's house and we're going to run the wires and mount the switch. i was running late for work today so i just dropped my car off and went to lunch and picked it up and rushed to work (no time for pics). tomorrow i'll have pics and hopefully vids too so stay tuned! lol

can you explain what this is and the purpose it serves for some of the guys who dont know... i mean... im not one of them... but... yeah...

[Hussain]

some people want the loud sound of exhaust when showing off or at the track and also the power gains..... then when it comes to having to deal with it being loud everyday gets REALLY ANNOYING. so an electronic exhaust cut-out is controlled by a switch mounted inside the car. you can go from super stealthy dead silent to obnoxiously loud with the flick of a switch......

when the cut-out is closed its like the way your car is now. then when you hit the switch it opens up a hole in the side of the piping allowing the flow to bypass the muffler (and the cat in my case ). iv'e tested my car at the track and noticed huge improvements from running it with no muffler and with no cat.....

[LongBeachCoupe]

Isnt your exhaust a straight pipe anyways? when you flip the switch... does it let the exhaust out before the cat? almost under the engine?

I started my car without the catback when i was putting it on to see what it would sound like... a 900cc motorcycle lol!

[RobPaulson]

that is sick dude, sounds exactly like what I would want, but is most likely very much out of my budget.

Hussain can you take a look at the thread i just posted in the performance section, I had a few questions about going cat-less

I have herd of E cut-outs before, but are they legal? Also, does anyone know if letting the exhaust fumes out of the car before the cat are harmful to the driver and the car itself? I don't think I've heard of anyone putting one on before the cat, only before the muffler.

[Hussain]

i've had the car with no cat on before and a Y-pipe is under development for the altima coupe that gets rid of the cat...... so you don't need the cat. as far as it being legal, i have no idea. they might look at it as when its closed its like being stock. or they might look at it as tampering with emissions. either way, if i get busted and they get mad i'll just go back to the muffler shop and cut that section off and replace it for $20. then come back and get it put back on for like $40 lol

where are my pics at ?

[Hussain]

my friend is supposed to email them to me...... on my way home just now i saw a Nismo Z and i was messing with him the whole way home when we were in traffic (not driving wreck less, just had the cut-out open and playing with manual mode). then we end up at a red light together. light turns green and i hit the gas but it looks like hes not going to go so i let off and then he floors the gas. so he got a better start then me but the actual race, he wasn't really pulling on me. once my RPMs got up, thats the distance that stayed between us the whole time. so the Nismo Z that i raced was a tiny bit faster then me with the E cut-out open

how hard is it to set one of these electronic exhaust cut out? cuz im thinkin of doing the same thing.. getting striaght piped.. and getting that cut out i save like 600 or 700 by not getting the artisan or any other exhaust.. but i gotta hide it from my parents so this is a biG!! + for mee i gotta no how to do this hehe

[Hussain]

lol ya i'm actually thinking about putting a resonator on my car cuz i have a Magnaflow cat-back exhaust and no longer need it to be loud now that i have the E cut-out. easiest and cheapest way it to do it AFTER the cat.... heres a pic of the cat when i took it off (i put it back on lol)

when i put the cat on i didn't put that flat part of piping, i have that part 3" and thats where i have my cut-out mounted. so if you want to put it before the cat you would have to have a muffler shop replace that flat part of the piping..... the cut-out was $171 shipped to my friends door (didn't want my parents to see it lol). costed $60 to have the muffler shop put it in (they usually charge $80). then me and my friend ran the wires and drilled the hole....

Legality will vary by state; any state that frowns upon messing with the emissions system will say this is illegal.

Does it hurt the car - no, but that cat was put on there to reduce the emissions output. So saying the cat is not needed is technically incorrect. Yyou may not "want" it, but the Earth thanks you for poisoning her a little more.

Does it hurt the driver - probably not. If you are at a stand still there's some possibility that the exhaust gases could be vented into the car but you are more than likely having the cut-out open only while you are racing so are generally in motion most of that time.

actually, it's been proven that without that 3rd cat the car will still pass a emissions test but if your state (like California) does a VISUAL inspection then you will fail. so according to what i've heard (from the ppl making the cat-less Y-pipe) it wont make any more pollution in the air then the car that pulls up next to you at a light... you still have the other 2 cats that have sensors and according to Stillen we also have cats IN the headers so those would still be there

Some people were asking about the emissions aspect and your statement makes it sound like its equivalent to keeping the cat there, but its not. A straight-pipe does not capture any pollutants; the cat captures some of them. Whether or not the difference is enough to make you fail emissions doesn't change that. Whatever emissions the person's car next to you is putting out has no bearing on what your car is putting out. Some people's sense of social responsibility directs them not to unnecessarily increase their environmental impact. That statement you made would steer these types of people in the wrong direction.

I'm not preaching against doing this, just wanting the people who are considering doing it to be able to make an informed decision.

+10 for a well said statement, momma earf thanks you!And depending where the pipe cuts out, you may find yourself keeled over the wheel while your waiting at a drive thru!

[Hussain]

thats why you close the switch at the drive through lol but ya, i agree with the other guy's statement........... my friend is hella lagging on the pics. i forgot my external hard drive at home or i would have just got the pics and would of had them uploaded hours ago lol

[reflexx]

ya im thinking of doing this.. but ima wait for the Y-Pipe then do this its the same situation right hussain? it can be done with the Y-Pipe from racingline?

[mrodrig2]

You can put the cut-out anywhere you want as long as there's enough space to fit the opening/closing mechanism and enough length of wiring. It's just sensible that you put it somewhere closer to the front and before the cat or y-pipe if you go that route. It wouldn't make sense to have it after the cat since the point of this thing is to have free-flowing exhaust and that location would be restricted by the cat.

[Hussain]

ya you could do that cuz the racingline Y-pipe eliminates that flat spot in the piping along with the cat. if you go that route, when you get stopped by the cops you just unbolt it and put the stock part on..... you would still have to go to a muffler shop to have them connect the E cut-out to the Y-pipe but that shouldn't be more then like $80 or $100 tops (cost me $60).

[reflexx]

alright thanks alot for the input guys ima jump on this as soon as the y- pipe comes out

[Hussain]

ok, FINALLY got VIDS!!!! i made a fly by vid at WOT but there were other cars driving by and it was at night and not that great so i just deleted, will make more vids later. next wednesday i'm going to the track with a bunch of my friends so ill let you guys know what i get in that thread along with pics and vids

heres a vid of me reving it..... let me know what you think of the cut-out and also my magnaflow cat-back exhaust when the cut-out is closed (when the camera guy walks to the back of the car)...... ppl have asked for exhaust vids for a while

and heres another vid of it while we're driving in the car

Ok well here's my first post and the pics of the install I pretty much did/helped Hussain with.....This will NOT be a full "HOW-TO" being as there isn't enough pics but it's pretty self-explanatory.

Ok I don't have a pic but we ran the wiring from the cutout along the subframe(ziptied) and behind the sideskirt and up the side of the door, we then took my antenna off my srt-4 to pull the end piece through the rubber boot which contains the power wires for the door, and that leads under the dash(everything is zip-tied up and out of the way). I did not know which wires of the Altima Coupe were power wires so I extended the switch power wire under the steering wheel to the cig-lighter power wire under the radio(Spliced and heatshrinked). Now that that's out of the way let's get to it.

Here we have the main portion of wiring and toggle switch..... The cutout height above the ground(Stock Height), compared to standard water bottle..... Took of the underside of dash to see if it will fit next to TCS button.....it didn't. Ok well here as you can see is what happens when you mark a spot for a hole before checking behind it. Behind it there was a plastic reinforcement type piece that was in the way so we triple checked and moved it to a better location.... Now I don't have a pic but when you have the plastics off you will see probably the biggest bundle of ground wired to 1 chassis bolt for the ground, I ran the switch ground to that location...Here is a somewhat decent pic of the power wire being ran to cig-lighter power wire..easy to get to from passenger side....

And FINALLY a pic of the first opening....... Hope the pics work

OVERALL IMPRESSIONS,Now the way his set-up was stock it was fairly quiet. I remember him saying "Man I wish my car would pop and burble like yours........"That's the stage 1 doin that lol....anyways since I'm used to my car screaming as I build boost and such, his car does have a nice, loud, smooth growl. It's far from being annoying, and I probably saved him a few hundred dollars instead of buying a full exhaust kit that's not adjustable and may be too raspy or annoying. I think it sounds great and really sets it off with a pretty unique sound. Hussain you better be happy you had me to do it for you lol. Find a way to fix the hole and hit me up. BTW Nissans are "ok".....J/K fellas....lol

[916SilverRT4]

Can someone help with the pics? Don't know what went wrong.....

[Hussain]

its cuz its in a weird *** format, ASPX..... i can view them on my comp (justin emailed me the pics) but its trying to open it in notepad for some reason but i got it to work on my comp but i can't upload it to photobucket.... anyone know how to fix this or convert the pics to a different format?

[Tommy:]]

You could try printscreening them and saving them as a jpeg

[mikegtr06]

ok so i right clicked on the pics and went to properties and then copied the url into my browser and that worked and so i attempted to instert them and that was a no go. as you can see.....

[Hussain]

thanks mehdi

That lets the exhaust out RIGHT under your seat!

Seriously... you need to be careful sitting in the car (or bringing children, infants etc) around because its as close to putting an exhaust hose in the cabin as you can get!

Does it sound like a rice rocket motorcycle? a "Waaaaat" sound?
