Research video from the R&D dept. at Borla shows how the Ford valves respond to rpm changes in all driving modes. 2018 Mustang systems: www.borla.com/ford-2018-musta...
@@codcade no, it's an option during the build and price stage (extra thousand bucks)...and then if you're buying from a dealership prebuilt, and you don't want active exhaust then don't buy the specific mustang that has it. You can just legit have them just do a search to nearby dealerships with all options of the car you're looking at, minus the active exhaust, then boom.
Nice video....most of the time I am in Normal drive mode. I have the exhaust in Track mode all the time. I also deleted the resonator and installed a H-Pipe. It is loud and sounds awesome. Loving my 2018 GT.
hey quick question, so the active valve exhaust is only in the muffler in the back right? if i add an x pipe or h pipe and have it on quite start it itll still be quite?
So when the car is in quiet mode are the valves actively fighting back against the exhaust or do they just sit closed without having to apply pressure? So if you put the car in quiet mode then remove power to the active exhaust, will the valves stay closed when driving or will they just fly wide open due to no power?
@Borla can I go to a muffler shop and ask them to cut out my active exhaust and just weld on a muffler to the active valve and still have functionality?
So the muffler is a mostly regular muffler and the valves open up depending on what setting you're on and what rpm the engine is running at that moment?
I have a question, what direction are the little springs on the motors supposed to be installed? There's only two ways they will sit and I've seen them both ways. The Borla install sheet shows them sitting (with the actuator post in the "bottom left" corner if you are looking down at it) with the widest round portion facing "up" and slightly "left", and I've seen them the other way, like in a CJ Pony parts install video of a ATAK system? Which is correct? Or are they side specific? Or does it not matter as long as they seat in the grooves and don't bind?
Hi. Thank you for reaching out. It may be possible to change the factory tips without losing your active exhaust valves, but it will be difficult. You will have to cut the tips after the active exhaust valve. Also, you would have to make sure that the new tips you choose will fit with the valance.
how does the active exhaust compare to GT without the active exhaust. In other words is it worth the option if i plan on keeping it on track mode all the time. I assume thats how a GT with out the valves would sound. or does the active exhaust in track mode louder than stock GT without active exhaust
I drove both and the active exhaust is louder and makes a rip sound on shifts, sounded amazing. I bought a GT without them though, I may add electric cutouts and hope for the rip sound on shifts
I was always debating as to whether I should get a muffler delete on this car but track mode is pretty much just free valve so like I might get one of these
Harry Jerry one of these what? They are just showing the stock valve actuation. Yes it is a neat feature, but the added complexity makes aftermarket solutions very kludgey IMO. If you know you are going to throw an ATAK or Extreme on the car then don’t do active exhaust...again IMO only. Active exhaust with the switchfire x pipe or the ford performance side exit xpipe is all I’d do unless I had an issue with one of the OE components.
Muffler delete is completely different than track mode. The muffler is still there, but it's allowing flow through the muffler baffles and then both exits. Muffler delete is just that, no muffler. A delete is much louder than track mode
The behaviour in Sport mode looks strange to me. Why do the valves continuously close, then open, then close again? There are even times when they are closed almost completely. Shouldn't they always be in a position that's wider than Normal, though not as wide as Track? The same behaviour, though to a much lesser extent, can be seen in Normal mode. Only Quiet (always closed except at high revs) and Track (always wide open) seem to make perfect sense.
The 2018+ Mustang GT has quad exhaust tips. Only the inner tips on each side have active valves that open and close based on throttle input. Even in quiet mode the valves will still open.
Hey Borla are you guys going to make an exhaust for the 18 mustang that does NOT have the active exhaust? So that we may fit it on our 2016 gt with Roush rear valance.
Unfortunately, we would not be able to guarantee fitment with the Roush rear valance. Our dimensions, pipe routing/spacing will be based off of the factory system.
It may fit perfectly fine. We just can't guarantee that it would as we will not be test fitting it on a Roush rear valance. If the Roush valance cut outs have the same dimensions as the factory valance on the 2018 Mustang GT then there is a good chance that it will fit.
Does anyone know answers to the following questions: 1) how many wires control the valve? 2) Is the valve opened further simply applying a higher voltage across 2 (or more?) leads of the valve controller? 3) Is it 0VDC for closed, 7.25 VDC for half open, 14.5VDC for open? (in other words, is its actuation linear as the voltage is increased?) 4) what is the current draw at full voltage? 5) If I can source some take-off valves from a mustang that had these valves removed, are there any after market controllers available? Thanks
I was about to make a video to explain this.... But I'll just share this video. When will you have an exhaust to compete with magnaflows active exhaust?
I just got my active Valve Borla attack exhaust done yesterday. I will upload vids soon! Im 1 of the 1st if not the 1st to have it done! IG @murduredmustangs FB @jackroush
Hello! The system in the video is the stock exhaust to show how the Active Exhaust works. With our Cat-Back system, you can expect a gain of about 10-12 horsepower on a stock vehicle. You may also be able to find third party dyno results of our Active Exhaust system for the 2018+ Mustang GT. Here is the link to our video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JbfYzekuxt0.html
Thank you for reaching out. Unfortunately, we only have active systems for the 2018+ Mustang GT as they come with the option from factory. Sorry about that.
www.mustang6g.com/forums/threads/2018-active-exhaust-install-guide.101913/ while this is for 2018+ this method can work for all cars as its employing a switch instead of using the selection on the car
Don't worry about him he's being pedantic. Anyone with half a brain knew what the video was about. 1st clue would have been not installing a goddamn video camera inside the Engine.
Poor valve design. That will rattle like a pneumatic drill after a while, before Ford issue a 'fix' to epoxy the ceramic pin at the base of the valve like GM did!
its really only there to not piss off the people next door at am hours. on track mode its is way louder than a manufacturer would ever make it with out the quite funtion. you can hear a cold start in track mode a mile away...
Hi! We removed the Active Exhaust valves from the stock exhaust and made a rig in order for us to see how the valves behave in different modes. The valves are in the front passenger seat so they aren't changing the exhaust sound in the video.
Track and sport are the same. But this made no changes in sound at all. On the stock 18' quiet mode is as quiet or ever so slightly quieter than a 2011-2017 gt. Normal sounds like a mild exhaust upgrade on a stock gt. And of course sport/track soun slime a full cat back system.. but for a Borla system, there was no point in putting the active valves on the aftermarket mufflers. Pointless.
The purpose of this video is to show what the Ford valves are doing and how they operate. We re-routed the wiring for the valves to our jig inside of the vehicle. Therefore the exhaust system that was on the car did not have functioning active exhaust valves. We plan on offering several exhaust options with active valves and without, and we will have videos that compare the Borla sound levels to stock. Stay tuned!
Stupid. I want my car to sound a certain way, this is just something else for manufacturers to put in a car, break, and have the customer pay through the ear to replace. No thank you.
