Straight pipes. That red truck was one of the worst running & sounding I've heard on here.

[@sdusb1243]

Yeah that thing needs other work before a muffler, lol

[@r.t.1942]

the z85 needs a tune up it's missing

[@LandonClimbs]

Missin badd

[@lsgt5132]

Needs something for sure.

[@vtx1300c74]

the straight pipes turn a regular old truck into a thing of beauty

[@gmega8]

Z85 with that chug chug idle wouldn’t be surprised if it stalled half way down the road. 😂

[@Silvermoss-Auto]

"Like a rock!"

[@eddiecampbell5925]

The gray truck sounded awesome!

[@landscapingspecialist]

Wow i just bought an ‘04 sierra w this motor! Looks like ill have to get some longtubes and a magnaflow 👌🏻

[@SteveStoltz]

Sounds like they need a tune up on the red truck.

[@adamgugin3012]

I was gonna say the same thing

[@lsjionredlinesupercharged2049]

Agreed

[@TerryByrdJr]

Yeah it sounds like shit

[@98silverado]

Red one . Didn't even sound like it's on

[@mikewasko4964]

4.8 are notorious for having throttle body issues. If it's starts to lag ,spit and sputter over 3500 rpm , it's most likely the throttle body. $190 at auto zone and about 20 min of your time it will run like it's brand new.

[@nah6430]

I think my completely stock 2001 Silverado 4.8 sounds better than the red one lol, I'll be straight piping it though

[@erichaley6776]

Gray truck sounds awesome!!!!

[@mikewasko4964]

I bought a 2016 Silverado 2500 with 6.0 brand new and cut the muffler off and replaced it with a peice of straight pipe the 1st day i had it. No muffler needed and everyone always compliments me on how good it sounds where ever i go and ask what muffler i have on it. Ive never been pulled over for noise and its just got a mean sound that isant over the top.

[@smooth235]

That red one sounds like a loopy cam

[@lenwoodcruze3594]

YIKES! Definitely a big NO to the Magnaflow setup..... what was wrong with it?

[@gunnykiller1623]

Sounded more like a engine problem more than the muffler

[@mitchlehammers1883]

i think it needs engine work, has a bad miss, plus I never seen a 1 in and 1 out muffler that sounds worth a crap.

[@itstherightone5179]

The red truck has clogged catalytic converters.

[@joseluisespino185]

i have a 2005 z85 after seeing this im straight piping mine

[@Chris-pz4mb]

I didn't know GM made a 4.8 5 cylinder. 😆

[@richgwozdz8580]

Bro my I say that every time I restart my 4.8 till i rev it up and it clears out it sounds like a 5 banger lol

[@BradHuey1992]

I liked the duals

[@AdmiralRustyShackleford]

Red truck giving that Magnaflow a bad image. Should've spent his money fixing it up first. If the engine is on its way out, I'd hack the muffler off and call it good, wouldn't spend any money on it.

[@Low4.8]

I had true dual straights coming out like the side like the red truck and I had the cops called multiple times on me for them

[@carlos5.030]

The red one is dying

[@ightbet4054]

What is that called for the silver truck liek half the exhaust?

[@williamhoffman6133]

I did this to mine. Will hst hurt my tires?

[@kankan572]

Isn’t straight pipe just everything is gone like muffler delete etc? My son has a straight pipe Silverado that he bought from a guy that had it completely customized but his is LOUD LOUD!!!!

[@KR_Diecasts]

Straight pipe wins !

[@Ran_Ptat]

Yikes, that red truck doesn’t sound very happy😬

[@andyworgess8998]

Grey truck was great

[@mitchlehammers1883]

seems like it rains a lot there.

[@mattkiser9965]

I have an '02 Silverado with the 4.8 V8 in it and a single in/dual out Flowmaster Super 10 installed and it isn't loud enough for me especially at idle. Would you say a muffler delete would be the route I should go?

[@mattkiser9965]

@M Jr. I ended up doing true dual catback straights with an X pipe and it sounds awesome!

[@keatonmoss7366]

@@mattkiser9965 I have the same setup and the same exact problem the super 10 on the 4.8 just isn’t quiet loud enough, but I wanna know how clean does the x pipe sound with those true duals.

[@mattkiser9965]

@@keatonmoss7366 Honestly the X Pipe really sounds awesome with a true dual setup. As long as you leave the cats intact then it won't sound super clappy or annoying. I have true duals 2.5" diameter pipe with an x pipe and it is just about perfect for me. I have thought about taking the x pipe out just to try it out for a while but I'm afraid it will be too loud. If you want loud and smooth then go with true duals and an x pipe but leave the cats installed.

[@frightenedskillet1051]

The thing about 4.8’s is they flow almost nothing at idle as well as all of them idling extremely low

[@user-vj5bz4vc9p]

There was no “Z85” package for those trucks, that’s just a 2WD owner that wants his truck to be a 4WD z71 so bad , I think his main focus is a tune up, not a $300 exhaust

[@doug42780]

I have a 00 dodge durango. What would be the best sit up to put on it. I want it to be sound deep

[@user-vj5bz4vc9p]

Don’t put a sound system on a Durango, please

[@joanrodriguez5848]

Everyone says straight pipe but drive one truck with straight pipe for few days and you will get annoyed lol

[@AdmiralRustyShackleford]

If it's out the back like this, it's not loud in the truck. I ran straight pipes on my old truck in high school (no cats or muffler, sounded awful) and it wasn't near as loud as you'd think.

[@joanrodriguez5848]

@@AdmiralRustyShackleford I have my 2011 Ford F-150 with the 5.0 had straight pipe with no cats 3” all the way it sounded nice but damn it got me annoyed

[@joanrodriguez5848]

@@AdmiralRustyShackleford after that I added a carven r and was good but same thing a lil to loud, now I have a magnaflow 14” and is to quiet lol

[@AdmiralRustyShackleford]

@@joanrodriguez5848 Has the Magnaflow broken in? With no cats it should be fairly loud.

Red truck sounds like a lawnmower

That thing ain’t straight piped, straight piped is no cats no Muffeler an true duals🤦🏼‍♀️

Is the 4.8L reliable?

[@darkside2521]

My 4.8 has 272000 miles of being hammered and going with out no oil in the engine for months but still wont break at all , I been try to swap a 6.0 in but my 4.8 thinks it's God and refuses to die. 😐

[@str33ttun3r9]

Red one misfire ? Lol

[@Kenny370]

Owner of the z85 needs to spend his money on maintenance before buying an exhaust

[@Powerstroke_Co]

Red truck sounds sick 🤢

[@Thebumpinthenight]

Red trucks need a tune not exhaust work

[@98silverado]

It's got headers long tube u can see. Red one. They missed that. And wtf it's sounds horrible

[@the_graham20]

that z85 sounds terrible. thing needs some work lol

[@xavierbratrsovsky9464]

That red one is not healthy

[@thesoggybaguette4465]

Those 4.8s just don't sound anywhere near as good as the 5.3s and 6.0s

[@JohnSmith-xx1lx]

MagnaFlow sounds horrible. Straight pipes for the win by far.

The red truck sounds like shit. Not the mufflers fault.
