I was in your position about a month ago. What every told me was it depends on your personal preference. Do you want it real loud? Or do you not want interior resonance? Also, people will differ on the same setup. Loud to one person might not seem like anything to someone else. Some are more sensitive to drone/resonance than others. You will get about every big name exhuast setup mentioned to you by people and their personal preference. Flowmaster, Magnaflow, Borla, Dynomax, etc.

 

What I did was went on Youtube and just searched different exhaust sounds from full-size pickups. I ended up getting a Flowmaster Super 40 straight muffler swap and I really like it. I like 'em loud though. I haven't had the chance to hear it outside yet except for idle because no one besides me has driven it since but interior I really like. With radio off and windows UP I can it idle at a stop and it's got a mean growl at take-off with "sweet spots" at about 1500-1600RPM's and 1900-2000RPM's during normal driving. I can't hear any thing really at highway speeds. Just a light growl.

 

What kind of engine do you have? That will make a bit of difference too. I've got a 4.8L V8 so I don't have to worry about AFM and can't comment on that.

I have glasspacks on my '07 Silverado and love 'em. Nice and loud and I get lots of compliments on the way it sounds. I have the 5.3 in my truck and I have disabled the AFM via the Predator so I don't have to listen to the ricey sound when it shoots in to V4 mode.

Yup, its a hand held programmer. AFIK, its the only hand held programmer that lets you disable the AFM.

 

how much did the programmer cost?

Get a Black Bear Tune, a handheld programmer aint worth the money.

My friend has AFM on his truck. there is a slight difference in the sound when it kicks into AFM. BUT it rarely comes on. Also a good tune will get rid of AFM if you find it annoying.

 

Also as for what brand...don't get Flowmasters!!! I got a Goerlich's Xlerator system for mine...it is very similar to Magnaflow but at half the cost (mine was $250) and to my opinion better than Magnaflow! Very nice beefy deep sound. Quiet when you want it to be and loud when you want it to be. Very good throttle response, performance, and MPG gains! Look up your truck under the performance catalog at this link: http://www.goerlichs.com/catalog.asp

I like straight pipes, but then again alot of people dont like it. I have heard alot of 5.3s with straight pipes or even just a muffler delete and i think they sound awesome. I personally dont have a truck yet because of school and money doesnt grow on trees but when i do get a truck its probably just gonna be straight piped with the cats. I have heard true duals is kinda hard to do with the O2 sensors and cats on these newer trucks. But its what you want, not us. Its your truck, and make it the way you want it. I would say if you really want it to be loud then go with a straight pipe. If you want a nice tone then go with a catback of your choice or even a direct fit muffler of your choice. It also depends on how much you want to spend.

HAHA, man you are the dude I was arguing with on Youtube. Well not arguing, but maybe not believing you got 27+ MPG with your truck.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      No, not yet. Hoping I'll have something a little more definitive in the next day or 2. They seemed to be very confident they can order it. I do have some understanding of the whole allocations and restraints stuff so we'll see.   I think this is what I'm looking for.   3000 ORDER ACCEPTED BY PRODUCTION CONTROL

      Then you haven't read your book. It also says check every 400 miles.   If you need to add multiple quarts in that distance then reading the stick isn't the issue. Put the two together and it will make sense. Read it all.

      Weird drivability problem

      By CNH-320 · Posted

      Following up on my topic, I put an O2 sensor in it which seems to have got rid of all the b2s1 codes (I ended up having multiple codes). Next I’ll try to figure out the P0011 but I might focus on exhaust manifolds first, they’re getting pretty rusty. I’m hoping this thread will help someone in the future.

      My expectations are a bit higher.    No faded paint or dry rotted plastic/rubber. I use a dressing and a ceramic sealant. No hazy headlights.  No door dings. Small dent in the front bumper. All rock chips repaired. No brush scratches. No windshield chips. No fender benders. Limit damage due to a proactive plan the included ceramics and PPF and prompt attention to any exterior issue. NO RUST. Stays out of the salt and had the rear wheel wells Line-X coated as well as the bed which has a bed rubber and has been under cover since before I bought it. Washed and detailed regularly. Rex chewed up the tow button, got whacked and the button replaced the same week. He's leaned his lesson. If I can train a dog the kids are easier.    All suspension is original save the King Shocks I installed very early on. 50 years ago dad told me a good shock will keep the screws in the dash tight and the front end mint. He was right. Everything within new spec yet, tight and aligned well several times. Coolant system is OEM save the modifications I made early on. Not a single leak anywhere on this machine. (Did repair an intake leak on #4 during the HPFP replacement.) The injectors I replaced didn't need to be. They checked out great. One of those, while I'm in there with the manifold off and the fuel rail apart things.  Not a stain or abrasion one to the upholstery. Have kept is covered since new. Never had a carpet, it's a work truck but the carpet squared I laid on the floor have keep the factory rubber liner MINT. Ceramic wind tint helps preserve the interior.    Original BRAKES with 60%+ left of the pads and rotors mic excellent. We just did a full preventative brake service. Disassembly, clean inspect including measurements, lube, Dot 4 power flush including ABS system.    OEM battery. OEM vacuum pump. In fact the only things not OEM are a pinion seal the high side pump and injectors and a small plastic shield around the starter. All hoses/belts etc.. are still in service and doing well. Original tires lasted 125K and had I known some additional details would have made it to 150K with legal tread. (Date out is six years, not 5 and Continental says they are good for 10 so I pulled the trigger to early)   I never let my children or grandchildren run the show. Feet on the floor and hands in your lap. Dog gets a pass.    A truck is a machine the gives you back whatever your willing to put into it. Same as a computer or a butter knife. I use a shovel but I scrap it, hose it off and oil it when I'm done with it. My original spade I've had 60 years.      Set the bar higher...you spend less money. No, before you ask, I have spent a fraction of the cost of a new truck in my entire maintenance program including disposables, filters/fluids etc.
