Stock or quiet Muffler with Headers?

I am looking to quiet down my exhaust, by a lot. I currently have American Racing longtube headers, no cats, and a Magnaflow resonator ("race muffler" is what they call it on their website). The truck is way too loud. Wakes my neighbors up even cranking it in the garag. I think it sounds great when your pinned to the floor but can not stand the super raspy tones that it sends out at mid RPM.

 

I am wanting to leave the longtubes w/o cats and add a muffler just cant decide which one to go with. I'm wanting to go much quieter so was wondering how much power I would actually lose if I were to install the stock exhaust with longtubes and no cats. Trying to describe the sound I'm looking for is very difficult but I feel like the stock muffler or maybe one that quiets it down a lot would be what I'm looking for. The only thing I can think of to describe is the sound of a stock Z06 Corvette. Obviously it would take a lot more to achieve such an amazing sound but hopefully you get the picture.

 

To narrow it down, I'm looking for a quiet, inexpensive, exhaust that isn't going to make me lose power.

 

The ultimate goal for the exhaust is to make it quiet for cruising and have an electric cut out for when I really want to open her up.

 

Thanks in advance! Looking forward to getting this right!

 

 

 

Below is a video of what it sounds like now.

Depending on the neighbors stock may be your best bet without cats and resonator. You might get away with say a 22 inch Magnaflow or such but probably not without adding a resonator. Contrary to belief cats do tame down exhaust sounds considerably.

I dont have an answer for what you are looking for, but i just had to say DAMN nice High country!

I have kooks 1 7/8 LT catless Y pipe on order now and running Corsa Sport now.

I know some people run Touring mufflers and they are super quiet, not sure on the price though.

I'm running two knock off Magnaflows 14" and a 22" welded back to back and with non-catted headers and a blower it's still loud as HELL!

07 do those knockoffs have any packing inside to dampen sound? Magnaflows do so they will be quieter but probably not to the extent RaptorEater is looking for. Shoot even a Borla Touring is loud as heck in a 5.3 with LT headers and no cats.

Good luck with your test 07 hope you get the sound/tone your after. Like I said without the cats it's tough to get a good non raspy tone that won't wake up the dead or piss off the neighbors.

I have the 12909 Magnaflow 22" for mine. At idle most think I am stock as it is fairly quiet no drone when cruising... I am not running headers though... Removed the flapper, and resonator as well. When I gun it, it gets quite a bit louder... I doubt it will tame your catless longtube set up but it could be a good place to start. My understanding from the stock muffler cut in half images I have seen is not a straight pass through setup which may affect your performance gains of adding the headers. Just my thoughts.

I run the oem catback with my catless headers/y. I replaced the oem muffler with Borla 40359. The key in my opinion to keeping that sound down is the stock resonator, which I still have in place.

 

Maybe just try adding that back in first and see if it helps you.

Grab a muffler from a previous generation 07-13 6.2 truck, they flow really well, and sound great. On my 2011 6.2 Sierra I had Kooks 1 7/8" headers catless going back to the factory 3.5" cat-back, loved the sound. Nice and quiet on the highway, but had plenty of growl when you laid on it. That's the setup I plan to run when i get some headers for the new truck.

Thanks for all of the replies! So i guess the question is should i try a resonator, stock 2014+ 5.3 muffler, or 07-13 6.2 muffler?

Would you happen to have a video of yours? What are you referring to as OEM if you replaced the muffler? Just the piping and resonator? Definitely sounds like something I'm looking for. Thanks!

      OCI, not when but why?

      By Atlas · Posted

      And yet the median household income there is a hair over $50k and 12% of families and 16% of the total population lives below the federal poverty line. That's low, and high, respectively.   You can choose to ignore reality...that's not what I'd call affluent but hey, you've got yours so nothing else matters or could be true, right?

      It really doesn’t matter to me. Making a blanket statement that can be refuted will be. As I pointed out the information is out there. Hey google.

      My area is one of the most affluent areas in Texas. And yet affordable housing is close by. My family business pays top wages and turnover is very low. You can’t but people in a box if you want to succeed the opportunity is there.

      AC diagnostic on a neo-classic Camaro

      By Atlas · Posted

      It was previously working, but the continually running compressor threw me for a loop. It wouldn't be out of the realm of possibility that a 26 year old AC system had lost some of its charge and could be exhibiting low charge indicators, so I thought I had it licked. Add some refrigerant to get the low and high pressures in range like on the old 134 systems.   I learned the continuously running compressor is normal, and that I need to know how much is in the system, as well as needing to meter what goes in. I'm only used to working on older R134a and R12 systems that aren't variable displacement. This is how we learn...LOL.   Long story short, I had a 20% off coupon for a new Jiffy Lube that opened nearby. I took it up there yesterday and they did an evac/recharge using their brand new machine from Mahle. Had a good conversation with the guy, they loved the car and I was out of there for $159 plus tax. Digitally measured charge, exactly 1.5lb of refrigerant went in.

      In most areas of the country, wages have trailed CPI increases over time (let's say, since the 70's) and things like housing, energy, and food have vastly outpaced wages on the whole. Can't ignore that, it's very real.   That isn't to say there aren't ways to live in ways that mitigate some of that, including moving to cheaper areas of the country. In KNut's neck of the world, median housing prices in "nearby" Dallas are more like $500k. If you're raising a family and young in a successful career, your economic opportunities are probably going to be better living closer to Dallas than Cornhole. A 3 hour (6+ round trip) daily commute probably isn't tolerable for most folks. Grumpy mentioned economic migration; but we've seen what happens when people populate and grow an area. It becomes more expensive when economic opportunities come to roost.   One thing different now from back in the 70's is our quality and standard of living has changed. Healthcare is light years better, for example. But it's also much more expensive. And we have communication and information/tech tools that folks in the 70's could never imagine, and they're accessible to people of just about all incomes. Cars are light years safer, faster, and filled with tech advances. Homes are larger, more energy-efficient, and more luxurious on the whole, from starter homes to luxury homes.   Seattle was once affordable. My folks came here in the 70's with a lot of other people from California looking to escape uncontrolled sprawl, smog, and rising prices in the Bay Area. Seattle and the surrounding area has grown considerably; The home they bought for, I think it was $70k or $80k in the late 70's is now worth $1.2M today. The same house.   So while there have been obvious boosts in some areas of quality and standard of living, regarding opportunity, that's a bit more nuanced. It's really not possible for young people to get started in similar situations in areas of the country that have become "HCOL" (high cost of living). There are many more areas than before, which is to say they exclude younger workers or make their lives significantly harder. They have to commute farther and longer to afford to live in the area. They have to take outsized risk, take on more debt, significantly delay family planning. Or, they could move somewhere cheaper, but there's usually a loss of economic opportunity that comes with that. Even for the same job, it may pay a lot less in a LCOL.   What I don't like are Boomers with phones thinking they have all the answers and outright saying that if people stopped paying for their cell phone that they'd be rich. It's as stupid and misguided as people who think they'd only be rich if taxes weren't so high. Sorry guys, Elon proved you wrong on that one, I guess you're just lazy and blaming your own situation for the reason you're not wealthy. Mobile communication is basically an expectation in a modern society and workforce and it's often cheaper than having a copper landline these days, so... What's your point?
