Those electric cutouts are GARBAGE. Fighters Garage installed many of them, primarily on SRT-4's. They leak, the motors fail, they're a weld-in install....they're just junk.

That is an external cutout as well, it gives you straight out exhaust, which is DEAFENING on a rotary. And crazy hot exhaust coming out under the car, cooking stuff under the car.

Cutouts aren't the way to go unless it's a full on drag car or something, and in that case you shouldn't even be playing with cutouts but with straight exhaust.

I agree with Dale.. I would not get electrical cutouts. I actually like this unity because its mechanical and simple design.

 

Dale, i just got this miracle in a box because of you review. Everything looks awesome and well built, however i have one question. How did you get the adjustment line into the cabin? what is the best route? thanks for any advice.
dave

 

I ran it near where the parking brake cable comes through into the cabin. I did drill a hole there to route the cable through.

I have the controller between my seat and the center console, just tucked in there. I don't use it that often so it doesn't have to be readily available.

Dale

 

i have one for sale if anyone is interested.

 

Thanks for the quick reply Dale, i'll update this when i have everything up and running.

 

What size? I'm looking for the 80mm (3") one pipe style (not the flange style). Let me know. Greg.

 

Sounds like something I need... I always wake my neighbors up when I go to work in the morning...

What's the difference between the flange type and the pipe type? I'm guessing with the flange you can just bolt it where there is a connection between 2 pipes (after-cat obviously). Is there any difference in terms of reliability with the pipe-type vs. the flange-type?

 

The pipe-type (or weld in) does take a bit more work to install, obviously a section of your exhaust has to be cut out and the pipe welded in place. The flange type requires no cutting or welding, simple bolt-in install. Both are really as effective I would think for muffling sound and for performance.

Any updates re this thing? especially on the back pressure / danger side of things? your engines still strong?
im going to make up some plates to go in between my exhaust flanges tonight to restrict my exhaust and hopefully make it quieter. (will be removed after i pass a noise test)
Im a little worried about the backpressure damaging something.
Im basically planning on making a couple of flange/plates with only a 1inch hole in the middle..instead of 3inch..
Any comments re this? Will a couple of 1inch recuding plates be OK? or should I drill multiple small holes?? any comments/ideas/info re this would be good.

 

Back pressure/danger? Really? I don't see ANY problems there. How are you going to blow your engine? The car is SO restricted with it closed that you build no boost and are making no power. It's not hurting anything.

You could make restrictor plates but that is gonna be a pain in the *** to get to and remove. The big idea with the ECV is it's simple to open and close at any time, you can close it to pull into your neighborhood, but have it open on the highway to have fun. Close it when you see a cop, open once he's gone.

Also, with a restrictor, you have a hot piece of metal in the exhaust you'd have to remove when you arrive at the destination. No thanks.

Dale

 

^Yea, the only reason I was worried was because someone previously said in this thread they had an ECV and it caused them to blow their engine in about a week.. Ill stop worrying about that though
I cant pass my noise test with the ECV as its easily adjustable, which is not allowed.

Its a bit of a screw around, but im basically planning on putting the plates in, driving to my noise test - hopefuly passing the test. Then driving home and removing the plates, never to be needed again.

Im not going to be taking them in and out all the time, I just need to pass this test...once.

 

Of course, most sanctioning bodies have restrictions on that tactic as well.

 

so I just found this :

All controlled by vacuum, no hassel of manually open/closing.

That looks more like a throttle body of some kind, the housing looks cast aluminum.

Vacuum control is interesting, the Cosmo actually had a butterfly valve in the muffler to shut off one port that was connected to vacuum, but it wasn't straight vacuum, it went to a solenoid valve that applied vacuum at specific times.

Also, not much "hassle" with the ECV, just pull a **** or push it back in. Done.

Dale

 

This is going on my to buy list and all the way on top of the list. The exhuast noise is killing mme .
The apexi is cheap, but would preffer a vacuum controlled system.

Which brand is that vacuum controller valve? Company?

 

can this cable be hooked up at the throtle body linkage system? It would make sence for this flapper valve to work with throttle - for example at WOT the Flapper is wide open and at idle and low speeds its to the quieter closer position?

 

A simple return spring would do the trick. When you get into boost he back pressure will make the flap open and when you out of boost your flap would stay shut to keep the car quiet.

 

where do you get that valve?

 

If you put this in rotary exhaust, it will most certainly warp and no longer open/close. Someone else has already tried it years ago. It needs to be made of a material that can withstand the heat of a rotary engine.

 

Hey Dale, seems like a cool product. Now that you have 8 or so months driving it around, can you comment on what impact, if any, it's had on your MPG's? Thanks.

 

I only use the ECV on interstate trips, MPG seems to be the same. Around town it's just like having an open exhaust, so it's as good or bad as my right foot .

Dale

 

has anyone tried this

http://www.dynomax.com/mufflers.php?muffler=vt

this is something i would love to test , but myh car is 4" exhaust , and very dificult to get these goodies for
but the drone is absolutely killing me

 

i tried it back when I had stock twins, i used the 3in center in, offset out. Its quieted things down to a good level and didnt get drony on the highway like my greddy unit (forgot which i had it had a oddly large piping) and was placed as the rear muffler. The sound is a higher pitched slightly compared to my greddy which makes it harder to come in to the interior.
