What he needs is better heads. One of the main issues with stock LS 5.3 heads, is they start to drop cfm's in the higher RPMs. A little bit of head work or some custom heads with a nice intake manifold would boost way more horsepower than some simple exhaust and intake tube with a logo on it. He's not pushing much more than stock. Especially with as much as he paid to have all of this work done... could have made way more power with actual engine work. These LS engines do great as is with the stock manifold and stock exhaust. You don't gain lots of horsepower by changing out the intake tube/ filter. Changing from the stock manifolds to the long tube headersonly grants you another few horsepower. That's why I've never understood the idea of bolt ons like this. If you're going for a sound, buy the long tube headers. If you're going for horsepower, modify the rotating assembly.

[@noahtheviking1]

@@sethh8892 those heads are good tho

[@sethh8892]

@@noahtheviking1 I didn't say the heads are bad. But if you know about Stock ls heads, then you would know they fail in the higher RPM range bc of failing CFM flow. Around 5200 RPMs, the CFM flow actually goes DOWN. Meaning they're pumping less air in each cylinder at a higher RPM range... this is what they should NOT be doing. Again, a little head work and valvetrain work would have put more power to the ground than these weak bolt ons.

[@countrykindaguy366]

@@sethh8892 that’s why you look at shortys vs long tube in the headers category. The CAI and Exhaust does not void factory warranty and DOES add horsepower. I have both and have dyno’ed before and after. Once you start messing with the block, that’s when things start blowing up sir. Screw your CFM readings lmao.

[@musicmixcapecod]

Wow the sound on that dyno was amazing

[@richfarfugnuven6308]

Just an FYI on my old truck(5.3L Suburban) I also did hi flow cats and ditched the muffler as well as a larger diameter exhaust. It helped a lot.

[@yaelchavez4282]

What type of exhaust does it have

[@GustavoEscobedoJr]

Very nice bro. Clean Chevy. Keep it up.

[@joseguzman9949]

Keep us updated bro

[@navy_vet493]

Sounded like a manual transmission on the first run lol

[@caldergray3973]

any exhaust changes on these engines tend to make them shift kinda loose. and he had the towhaul engaged as you can see in the cluster

[@joshardy25]

thats because he had it in manual shift mode. look at the dash and you can see.

[@RidinChevySolo]

Calder Gray thats traction control, not tow haul. Tow haul holds gears longer and is slower, imo. Just lettin ya know.

[@joshardy25]

yes I know what tow haul does. but just to let YOU know that M on the dash stands for manual. That let's you change the gears manually.

[@jacksonross6409]

He had it in manual on the first run and regular drive on the second run

[@AGearHead4Life]

Good video and info man

[@alipontiac]

Big improvement.

[@sethh8892]

No lol. These LS engines are good and all, but their main issue with the 5.3 liter heads is the cfms start to drop off at roughly 5200 rpms. They're simply not able to flow the air. If he actually wants to boost some power into it, he should dohe should do valve train work and head work. A mild cam, quality valve springs, maybe a slight port and polish (or bigger heads to begin with) and he'd be pumping out 50 more horsepower EASY. All with the stock intake manifold, intake tube, and exaust. The intake and exhaust on these engines were really nice and definitely do not limit these vehicles until you start pumping out about 400 horses. Once you start getting up into their the stock intake manifold starts to limit you, and the exhaust isn't able to scavenge properly. The only time I think it's acceptable to add a k&n 'cold air intake' his whenever you're a high school kid that doesn't understand how horsepower is generated in a motor. You can stick a filter on the throttle body and call it a day... matter of fact get a intake manifold that can support a larger throttle body, and get a tune. More flow, with proper fuel to mix = more power.

[@63Imp283]

i thought 5.3s were weak, i guess i was wrong. i think i found my engine choice for my '63 impala keep up the good work

[@patrickjordan7359]

Nice truck bro, what exhaust system (or specific muffler) do you have after the LT headers in this video?

[@SnowAmbassodors]

Did you do a larger throttle body as well? I know most 5.3l engines come with an 87mm but some say with a 90mm throttle body throttle response is incomparable

[@kongchingpow]

Like a few other people on here...I'm wondering why it sounded manual the first time...I actually thought to myself that a manual is not very common in those trucks...and then on the dyno and the second run it was auto...idk. the power numbers are probably pretty accurate, but it really just seems louder. It did seem to rev a little higher though on the first shift.

[@scooterbobscout]

Them stock 5.3s are quick

[@TheManfromNibiru]

HAAAAAAAAAA! That's perfect ! 5.3 has some nads to it just from stock . I punched mine and almost when side ways so I know its over 300 HP ! Its all aluminum block so its light , great fuel millage for dual cab 6000 lb truck . 15 to 20 mpg .

[@SimbaCortez1320]

Yeah man, after we added the 373's and swapped underdrive pulley I noticed when 125+ it starts humming then vibrates, idk what it is forsure but im sure it is the driveshaft as well. im going to see if we can upgrade it.

[@smokendatires]

im running 4;10 gears and my humstarts at 90 mph. scared to take it past that. i need to upgrade my driveshaft aswell. Setup is 24's with 4:10, tune, K&N. Longtubes and full exhaust coming this week with a retune.

[@lorenblackledge7932]

I have a 14 I tuned it and the driveshaft snapped on me after 107

[@leeburks3048]

Drive shaft not ment to go over 100mph on them trucks

[@sethh8892]

@@lorenblackledge7932 how the hell do you do that? Torque is what's going to snap those drive shafts. Not rotational speed. Unless you twat waffles have some warped axles. These trucks and the Yukon/ tahoe can go upwards of 130 before you need to worry about that.

[@addictedtofishing7080]

More noise but i notice that you turn on the tow haul button and that reva more the motor and transmision but sounds great

[@oldassz]

I just ordered the pulley and front bumper cap from slp. What did you think of the pulley? Another nice little addition you may want to consider is the LS3 TB ( 90mm instead of 87 ). I put a jantzer ported and polished LS3 TB on my 2011 4.8 and I seem to notice alot more throttle response.

[@allancoates5863]

[@chinoYle]

Esta perrona la troka compadre.........

[@SimbaCortez1320]

I would go with longtubes, and i think the check engine light will come on but after you get it tuned it will go away. about the brand, I went with OBX but its all about how much you want to spend because the brand pacesetter is a little more expensive.

[@dapitbull2009]

Props man. Good looking truck. I have an 08. I kinda wish mine had traction control. Would help me out in Illinois winter months. Just curious how they tuned it. Use a programmer or try tune the computer itself

damn so you are making around 400 at the crank? thats awesome man

[@gunnerscustoms]

[@mjc_208]

Dis you have to do any other mods to the exhaust? Or did the LT headers just bolt in? And did you just do the headers and intake? Thinking about doing the same thing to my '06 5.3L.

[@jamesguralski5156]

Hi. Links to the headers? Links to the k&n kit? Did u do new cat n exhaust system? Links to that's stuff too! Please! Did you delete the displacement on demand system? Or did you totally program at out and or change Cam and lifters?

[@SimbaCortez1320]

yeah man, we started with LT headers, Intake then tune, and it ran good. After awhile we did the 373 gears and swapped the underdrive pulley, and we recently cammed it. It's a beast now. Next is the stall.

[@Still_Strugglin]

[@_E_B_]

I had a 2005 Chevy Silverado reg cab 5.3L with intake, headers, exhaust, 4.56 gears, and a tune... Also had a 2013 ram reg cab hemi with just a flowmaster super 44 muffler and it would destroy my modded Silverado from a dig, from a roll, at any speed. Chevys are nice. Rams are nice. But the Rams are just quick trucks. With a chevy... you really need the 6.0L or 6.2L v8 to compete with Ram and Ford. The 5.3 L v8 is a great motor for forced induction. But bolt ons...it doesnt react well to bolt ons unless you also have cam, heads, intake manifold, etc, etc. Simple bolt ons like intake, headers, exhaust dont net it much power... But nice truck either way...
