I installed a flowmaster super 10 series which they said is their loudest muffler. I  left the V4 flap and deleted  resonator. Ive had this new set up for 2 months now and there is quite a difference. I plan on taking out the V4 flap because at low rpms it makes the exhaust hiss a little, ( it does sound like a exchaust leak but I've had many people look at it and they say there no leak and that hissing noise is the v4 flap opening and closing. But driving around in tow mode takes that problem away and definitely turned heads. 

 

I hope this was somewhat helpful. 

 

I plan on going this weekend to have the Flowmaster 10 Series installed.. First just the muffler, start it and see how it sounds with the resonator in place.. if not to my liking then ill have them remove it.

But where is this V4 flap? is that inline somewhere in the exhaust?  Is that a job for the muffler shop? what does removing it do?

Depending on what year your truck is it'll be in front of the muffler of behind it. If you crawl under your truck you'll be able to see it.

Went first thing saturday morning :)  had them just install the muffler in place with everything else as it was and started it up, sounded ok, but really couldnt tell it was a 10 series at all, so had them remove resonator and flap and just dump it.. MAN what a difference.. def alot of drone in the cab, but only at certain speeds/RPM ranges.. but i love it.. more than the 40 series i had on my 15.

If i were you, id have them remove the resonator, keeping the resonator on keeps the truck sounding like its still stock. 

 

And the v4 valve is inline with the exhaust, located after the muffler. Any muffler shop can remove it, all they have to do is cut it off and weld in a new piece of piping. By removing the v4 valve it makes the truck sound alot better and takes away the hissing noise.

Is there any value to our OEM Exhaust once it is removed? I took mine off at less than 2k miles and couldn't bring myself to let them "just scrap it", however I'm not really sure if I have the room to just keep it around the house either. It still has the Chrome/Polished tip and the V4 flapper and everything else utilized with the stock setup.

ANybody have the CORSA dB exhaust single exit? I’m looking to get that for my 2017 5.3L but nervous about the V4 mode sound issues in general when replacing the stock exhaust. I’m assuming by installing any exhaust system that replaces the stock muffler, the V4 flap is removed? Also it says that the CORSA dB is made of T409 steel so I don’t understand why people on here are saying that it’s made of a lesser grade steel

I believe the Corsa is made from 409 stainless and the dB is made from 439 stainless.

I believe the entire Corsa Sport system is 304SS with double tip, and the dB is a 304SS muffler and single tip but 409SS tubing. The tip and muffler look great on my dB, but the tubing has surface rust.

How long have you had the exhaust on your truck for? And what area of the country do you live in?

I actually bought it used and have had it on my truck for almost two years. I live in Ohio and drive it daily all year round.

I have a Magnaflow Offroad Pro Series Exhaust on order right now, just waiting for it to show up but pairs nicely from a video I seen with the K&N 63 Series Cold air, will post pictures once installed

Anyone on here have the MBRP cat back? I have a Magnaflow 12909? 22" muffler, left the flapper ( zero drone) and resonator but it's too quiet. I can get the MBRP for $322 right now and if it's too loud for long family trips towing I can swap it back. I'm so ready to pull the trigger soon how it's "black Friday" lol.
I want a deep, powerful sound and not raspy and poppy. The videos I've watched make it out to be what I want.. I'm just nervous it will be too loud.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      By KARNUT · Posted

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
