Does anyone think it would be possible to have 2 exhaust options? By this I mean cut the exhaust system just before the muffler and put in an electric cut out, from the cut out, run one way to the muffler #1 (this one would be a more tame exhaust sound) and then the other exit for the cutout would go to a much less tamed, much louder muffler, muffler #2. For these purposes lets say that muffler #1 would be an 18" or 22" magnaflow, and muffler #2 would be a 14" magnaflow or a super 40 series American thunder from Flowmaster. After the mufflers, the pipes from each would them run to the same exhaust tip(s).

 

It's something I have been wondering about. I mean, we all have those times where you don't want to wake up everyone in the neighborhood or in your house becuase you are leaving early morning so you would want your truck to be a bit more on the quiet side, while at other times you are wanting your truck to just shut down anyone else who tries to roll up next to you and rev their exhaust at you.

 

Anyone think this would be something worth trying? After I get everything else done that I want to do to my truck, I may try this. Unless someone already has and had a bad experience.

Corvettes have what is called "Dual Mode" Exhaust. There is a butterfly valve in the 2 outside tips (4 total), that can be controlled by a remote (Called "Mild to Wild" Controller). The valves are controlled by a vacuum line, either open or closed. Closed = quiet rumble... Open = Ground pounder. Pretty cool system.

 

Not impossible to rig up on a truck, but it would take a lot of custom work!

Finally had the tips moved to rear quarter flush and with a slight stagger.   Sent from my HTC One using Tapatalk

The number of hours spent on any given forum are directly proportional to the number of dollars spent on subject vehicle.   Ask me how I know.

So I can anyone with the Corsa side outlet exhaust comment on the sound and drone (if any) in V-4 mode on the highway and around town? I'm very close to purchasing one but I can't find many reviews of the exhaust system. Thanks in advance!

Go to a muffler shop have a y pipe put in front of the muffler run a dual pipe with two exits. Weld header flanges on the tips with wing nuts, wild and mild. You could even run the wild side in front of the rear tire. You don't really have to flange the quiet side, you open the loud side it will just flow that way. Ive done it, its a blast.

Is there a way to control that from inside of the cab?

Yes, electric cut off. It doesn't take long to undo three wing nuts. Caution where gloves when hot.

Thanks man. After I do a few other things to my truck I'll probably do this mod. I've been thinking about it for quite some time but knowing that some others have done it before makes me want to try it more haha. But as I said, this one will be after a few things. Tint, lift, tires, light bar. After those mods, it looks like I may have a real "true dual" exhaust. But not how most people think of true duals haha.

Drone is terrible with my 14" magnaflow. Thinking about buying that AFM delete device from Range Technology. Plug n play and can remove when you want the AFM for long trips and what not. Its 200 bucks though.

Do not waste your money. All you have to do is shift your trans into Manual mode(I use M5 mostly) .and the truck will not switch to V4. Works great.The new trannys are not really "MANUAL" shift any longer. It will run thru first to fifth just like normal. and when you get on the highway ,flip the little switch on the shift lever to 6th and everyones happy. Just remember to flip the switch every time to M5 or you'll take off in first gear. After a few weeks it will become second nature and you won't even realize your doing it. It will seem like a different truck. Hope this helps. OH I forgot to tell you that when you do flip the switch to 6th the truck will go into V4. And be shure to use the switch and not the shift lever . Don't want to go shifting into reverse at 70 mph. :driving:

Its shifts right at red line too, sometimes on the 1-2 shift it bounces the red limiter, pretty cool. I don't go into m6 till after 60, no change in gas millage.

I just want something that is gonna sound good, with a nice growl, not be too loud on idle, and absolutely will NOT drone in V4 mode....there are so many choices. Anyone have suggestions?

 

I've heard good things on Corsa and Borla cat backs. And they are guaranteed no-drone.

Corsa if you have the dough.. aFe if you like your wallet fatter. I had the corsa on my 05 and loved it. Also, now am running the aFe on my 14 and love it. Helicopter sound is there when switching from V4 to V8 but in town I run it in m5 like everyone suggests. On the highway there is no drone but get on the gas and you can tell its there.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      Most thermostatically controlled ATF systems use a 'wax' pill just like the one in your water thermostat. They work on the expansion volume of the wax and the pill is constructed in such a way as to limit the travel to remain within that range. This means it has an opening temperature often called the 'cracking temperature' and a fully open temperature. For whatever reason oil is designated by it's fully open temperature and water by it's cracking temperature.    Between the two it the "Regulating Temperature" The entire range is about 20 F from closed to open. In your example the lower limit, opening point of 145 F then has a fully open temp of 165 F and a throttling temperature of 155 F.    Thing is, the throttling temperature needs two things to work properly. Enough system load high enough to reach the minimum and a heat sink (cooler/exchanger) large enough to prevent any load applied from exceeding the fully open temperature.    If your system exceeds the fully open temperature it is screaming MORE COOLER.    Here is the silly part of the whole thermostat system where the oil is cooled/heated by the radiator. Nothing is flowing to that system until the oil temperature reaches the cracking temperature unless it is equipped with a minimum flow bypass orifice or a bypass built into the seating surface of the plunger. That system meant to get it up to temp quicker isn't doing a thing until WORK drives if from ambient to cracking temp. One a cold winter day, like zero F, it may never get hotter than about 110 F. Sometimes not even that.    People forget or are young enough to not know that until this millennia transmissions were cooled by the radiator cold tank alone and without a thermostat at all.  In the 50's they weren't even cooled. OEMs learn everything the hard way.    When an OEM tells you the trans "Works best" between 175 F and 220 F it means works best for THEM. The transmission thermostat is fuel play. If you watch you trans temps like I do you will learn that it may take a hundred miles if you are not towing and not driving more than say 55-60 mph on a zero F day to even reach 120 F and it might sit there all day if it's colder. Yet if functions perfectly over about 100 F. It may need to get a bit warmer for the fuel and spark maps to go without an multiplier.    Worry more about too hot. Use a cooler large enough to put that thermostat in range.

      Gas Prices

      Around 2008 if memory serves they took sulfur out. That was when diesel went up.

      Gas Prices

      By richard wysong · Posted

      Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas

      Transmission Temperature Hitting 220s

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      Some Assembly is Required

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.
