I just purchased a 00 cmc half ton 5.3l 4by4 and Am lookin at getting the super 44 muffler. I am too poor to run true dual at the moment but cannot stand a quiet truck (all my other vehicles car, sled, bike) have aftermarket. I will just go dual from muffler back. I would like some feedback on what you guys are runing and where to get the best deal. thanks alot

Flowmaster 50HD on my 6.0L.......never heard it from the outside but everyone says she sounds pretty horny!

i have a magnaflow true dual exhaust on my 2500hd. sounds awesome. fairly tame at cruise and idle but give her some gas and she growls. flowmasters are louder and they have that drone that i dont like. everyone has their own opinion when it comes to exhaust.

Cut the cats off and put on a 50 series flowmaster with a turndown befor the rear axel. Cheap and sounds great
This is what i got. Its fucking loud

I have a 99 f150 with the muffler cut out. no too loud and doesnt sound bad I also have a 94 f150 with the cats cut off and true duals with two cherry bomb glass packs. sounds awsome

On my 98 Ram 5.9 i have the exhaust dumped right about were the bed starts with no muffler. Everyone says it is the meanest sounding truck the have heard.

yeah right!

Remember to pass inspection, not sure what that means in where you are. We don't have inspection here. On my Fords I run dual after the cat(s), no muffler. I've only had older Chevys but that was always a no-brainer for exhaust.

none, straight pipes baby. Chevy silverado

none! I have a 2.5 inch duals. Cut that muffler off and run a Y with 3.5 or 4 inch tips. You will love it.. I have the same truck, its a 99 GMC half ton

Banks

Stacks...nothing but stacks.... Oh and it is on a 6 cyl chevy.... They look cool

Hey i know a kid that had A stack on a f-150 and even though it was really gay it sounded awesome.

I would have put stacks on my Dmax if I didn't have a tauneu cover. I'm thinking of cutting the cat off. I gotta see if it has any sensors on it first though.

i have a 40 series flowmaster on my truck welded in the stock muffler location and single chamber flows on my camaro, both are pretty loud

I have a Flowmaster 50 series SUV. I like it.

I wouldn't pay extra dollars for a flowmaster. There patent is up and there are companies out there making the same muffler for much cheaper. Here is a link to some cheap mufflers that are essentially the same as a flowmaster.

The single chambered mufflers will be the loudest. One of my buddies has a single in/dual out flowmaster original 40 series on a truck very similar to yours and it is badass. Put a single chamber on there and you will be noticed.

Flowmaster single chamber on a 03 5.3

Same on a 4.8

I have an Flowmaster original 40 on my 5.3 and its loud outside the cab, and fairly quiet inside until you get on it. Another friend of mine has strait pipe on his 4.8 and it sounds like a stock car, wont pass inspection either.

first cut out the cat as long as you dont have to pass emisions tests. next if you want really loud put strait pipes. but if you just want a nice loud put a cherry bomb but install it backwards so that the baffles dont grab as much.

Depends what truck you have, I know someone that cut out the cats on a 5.3 and strait piped it and it sounded like shit. I know another person that cut out the cats, put on some lt pacesetter headers, ran 3 inch diesel strait pipe and it sounds sick. All depends what your setup is.

Yeah I have a Duramax so It'll be fine. I checked it last night, no sensors. WOOHOO!

yea your good to go then. Idk why I thought the 5.3 with straitpipe didnt sound good, but its pretty good sounding. But its not as loud as you would think for some reason.

I know what you mean. My friends 5.3 wasn't loud when his muffler came off. But my friends hemi was when he took his off.

not sure what trucks or when they started but on my 2004 HD it had true dual all the way to the muffler, so it was easy to do custom true duals with glasspacks out at an angle behind the tires! wicked loud!

7.3 powerstroke thats been played with alot, runnin 4 inch from the turbo back no muffler then dumps in front of the pas side rear wheel. Sounds sick when she's rollin the coal.

for some reason dodges are always a little louder than anyother brancd with the same exhaust. maybe its all the fuel running threw them lol. can't beat cutting out the cats on any truck even with stock mufflers

the best flowing chambered muffler is the hooker "aero chamber", center in center out. it out flowed the flowmaster 40 series 2 chamber. remove your cat (check local laws first) and use one of these (or 2), it will sound sick and perform! i have 2 of these on my street driven drag s-10, its loud and turns EVERYBODYS head! they make them for cat back dual systems too!

i am running dynomax on my 78 z28 but they are not loud, honnestly if you want to go loud, buy flowmaster

cherry bomb, either glasspacks or extreme

ultra flow (i think thats what the brand was...) i had them on my f250 before i sold it and it sounded amazing

Why did you sell it? Used too much fuel?? What do you drive now?

yeah it had a big block and 33s so i was getting about 8-9mpg and i didnt have a job at the time, plus it still needed some work.... right now im driving a stock (for now) 91 bronco

got a 04 2500hd 6.0l with true duals, only 2 streak glasspacks then out at 45's to the back! very very loud.

ok, first of all with emissions: i have a 02 silverado 5.3 and instead of cutting the cats off, i just made a couple of cuts, opened them up and hollowed them out and welded'em back up. you will get a ses code, but go to any decent performance tuner and he will delete the rear 02 sensors. i have passed emissions with flying colors and it sounds badass and unique. right now i am running a single moroso spiralflow with a 3'' in and 3'' out dumped out the muffler. it was too quiet so i cut it in 3 sections, removed about 6 inches of the middle section, welded it back up and it sounds mean and offers just the right amout of back pressure. the muffler is only about 50 bucks from jegs.

i have a 02 5.3 sierra, i'm thinking of putting on straight pipes but i have a couple questions

-Can straight pipes be bad for your motor? Shouldn't you have some backpressure?
-Do you guys get pulled over a lot?
-I haven't even checked but is the stock exhaust welded or is it held together with clamps? Would I be able to easily swap back to stock for inspection? Do the sensors just unplug?
-Besides wanting to stomp on it everywhere, does this effect gas mileage?

Sorry for all the ?'s

Straight pipes will give you enough back pressure, but it can hurt you in the power department and your gas millage will most likley go down. I had mine dumped right after the cat which was very loud, but yesterday i had to put my thrush muffle back on due to i need every MPG i can get. I have never been pulled over but i have a friend who has, but he has headers and his truck is lifted so it sticks out a lot more.

Go to your local muffler shop and see wut they got for prices for mufflers, cats and pipes first. They will tell you wut you need and if it will work on your truck correctly or not. Ive put 3 different mufflers on my truck before i found the right one for sound and milage now i just run a high flow cat with no muffler, but its a older chevy so theres only one sensor to worry about. I dont know about yours sledmaine. Go to a salvage yard if you got one near you, you might get lucky and find a system off a right off if your lucky.

That's a good idea, you could save a lot of money
