Exhaust Idea?

I had a flowmaster installed on my truck and while its ok for ridding around town, the drone kills me on the highway. I had an idea to install both mufflers and use an electric exhaust cut out to switch between the factory muffler and the flowmaster. Anyone see any problems with this idea?

 

Thanks

I'm not sure what kind of issues you'll have with that setup... BUT, it would probably be a lot easier and cheaper to just get a muffler that doesn't kill you with drone on the highway, but still gives you a nice sound for other times.

Dunno what flow master you put on your truck but. The Force 2 system is what I have on my truck. It is a little bit louder than the stock exhaust at highway speed in the cab.. The only time you actually get a good noise from the exhaust is during acceleration. I looked on flowmaster's site I have the older force II system (mine has the exhaust tips that are bent not straight DOR). My system has a resonator just past the catalytic converter. It is very quite at cruising speeds but gives nice tone. (Think this is the system I put on my truck) If you just stuck a Flowmaster on the truck get a resonator and put behind your catalytic converter.... That should hush it up..

Keep in mind that YDXL has a different motor in it than your truck does. So, that will effect the sound a good bit, too... So, you might be able to put the same muffler on your truck, but that doesn't mean it'll sound the same (it won't).

If you are talking about an 07 and up YDXL you can put the muffler from one on your truck and it will sound very close.

Problem with the electric exhaust cut outs is they have the tendency to fail where they stick open or closed. I had a few on my race car, but ended up switching it out for a manual cut out after 3 electric failures.

I don't know how they would sound on our trucks but I have a set of two Magnaflows on my Grand Prix GTP and they sound sick! There is a bit of drown around 50 MPH but certainly not unbearable, and sometimes I drive at that speed and have a little fun with the sound. :)

a few of us have the Flowmaster 70 big block. No highway drone. A bit deeper and louder.

 

I just got the Flowmaster 70 BB on Friday and like it so far. No drone to speak of. It's only slightly louder in the cab vs stock through most of the throttle range and i get a bit more of its sound when up against buildings.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
