Yes you will. Long tube headers usually will set a catalyst efficiency code without proper tuning. A tuner can tell the downstream O2 sensors to ignore all activity, preventing the setting of code P0420 or P0430
Is there a big difference on daily driving, part throttle, trailer/hauling and fuel economy between stock manifolds and long tube headers? or the difference (apart from the awesome sound) is it just at wide open? I don't know if I want to spend that much on my 2015 5.3
BadAssEngineering all I can say is bottom end torque is "noticeably" better like climbing a hill or towing but I wouldn't say it's like putting a stroker kit in it better. Also mpg was only like 0.5 mpg increase
It is tuned therefore I don't have a check engine light. A good tuner has the ability to make the computer ignore all downstream O2 sensor activity thus not setting a code for catalyst efficiency on both banks
shawn cordeiro you’re right. unfortunately I did a tune the same time as the headers and it shifts later at a higher rpm as part of the tune. I should have in the “before” filming put it in manual mode and let it rev out to 6k rather than the factory 5.2k shift point. The sitting still revs are same rpms though cause in Park/neutral it’ll only let it go to 4k but with the engine under a load it does go 800 rpms higher in the “after” film
@@APMotorsports0 no near the beginning in neutral/park you reved motor more aggressively and favoured the camera angle for the long tubes Is there a way you could make another comparision video ? im wondering if theres differance in sound between shorty and long tubes I dont think theres much but everyone is different
Hi I notice your battery gauge is like my truck( same truck )is below 14volts ,is this normal for this trucks cause while I was on the road my battery gauge started dropping to about 12 or13 volts and stayed there didnt go back up till I pulled over turned engine off and turn it back on I thought voltage is somewhere above 14 volts when engine is running
Tony Tapuro mine has been doing it for years. I wouldn’t worry about it because I have not seen any negative performance from the vehicle that are related to voltage issues. Oh course yes it creeps me out seeing a gauge reading slightly off but if no problems are present then I wouldn’t try to chase it too much
Alex Perry .. Thanks got my truck second hand and no owners manual it's 12 silverado 1500 Ext.cab LT 5.3 4x2 rolling on 24s .. Did you have any clearance issues with the long tube headers and did you install any AFM disabler module for the 4cylinders issues I heard they go into 4cylinder mode to save gas ..that really sucks v8 should stay v8 mode at all times
Alex Perry .thanks my truck came with the aftermarket dynomax full exhaust and it felt like there is no low end torque or I'm not driving it right cause of the 24 in wheels I also added AF cold air intake to see if it'll make a difference I think their in there just for looks anyways cool truck and thanks
Tony Tapuro Hey guys if you're wondering about why the voltage goes down sometimes it's a weird program in certain newer chevys like this. In the ECU there's a weird little program that has the alternator stop charging the battery when it doesn't need to be charged. That's why when you shut your engine off and start it back up it charges it again because it resets and also because the battery was discharged from restarting the engine
I absolutely LOVE Chevy and GMC trucks. I eat very well and am building quite the stock portfolio making BANK fixing all these dumb as shit LM7's, L33's, and LBZ's up here in Alaska. Oh and AFM deletes. I can do those in my sleep. You CAN possibly get the WORST engine GM ever made and get you a 5.3 that has AFM & VVT.. 🤣 Oops huge mistake of a design.. lol. Those are what separate the men from the boys. Real men don't play with that garbage. They delete the AFM ASAP because it causes a myriad of problems down the line. I've reset a shit ton of AFM lifters. They catch later on down the line if you don't keep that screen cleaned out under your oil pressure sender on the VLOM plate.
Where did you buy the headers from?
@gavinpetty07 I purchased them from www.texas-speed.com/. ARH does make all their headers to order, mine took about 3 months to come in.
Man when you were gearing down that sounds wicked can't wait for my long tube headers and true duals
Sounds pretty dam good chevys for life baby
Do you need to tune it to pads smog and for check engine?
Yes you will. Long tube headers usually will set a catalyst efficiency code without proper tuning. A tuner can tell the downstream O2 sensors to ignore all activity, preventing the setting of code P0420 or P0430
Nice video
made it sound completely different cant go wrong with corsa and longtubes
A vid of how to down shift like that would be sick🔥🔥
I think its in tow mode, I have a 2014 6.2 and it will do that
its not that hard lol you just put it in manual and drop a gear
@@chrishansen7004 how do u drop a gear?
@@nnbsjesse2447You pull to Gear stick down after drive it has a manual mode and then you can use the plus or minus

Thanks, Alex, I would love to get a set, maybe for Christmas, I need to save some cash for it lol
Alex Perry 0.5 mpg with a tank of gas that could be like 10ish or more miles
@@ethan41623 shorties and custom tune gave me 1.5 mpg better
Was it tuned or nah, and did the high flows give you a engine light??
It is tuned therefore I don't have a check engine light. A good tuner has the ability to make the computer ignore all downstream O2 sensor activity thus not setting a code for catalyst efficiency on both banks
Did your notice any considerable gains?
I would say the gains were “noticeable” but unsure of exact numbers because I have never been on a dyno
What cat??
Did you just cut two cats into the off-road y pipe?
What muffler did you have on before the headers sounds good
Rigo Ramirrz it is a Corsa DB series exhaust
What size pipe you running from y pipe? & tip sizes ?
Jason Reyes it is 3” from y pipe and the tip is a dual 4” tip
What muffler u running
Dylan Mann it is a Corsa DB series muffler
gearing down realy sounds like a ol school 2 stroke Detroit desiel gearing down dont belive me look it up
You are not wrong. Gotta love the screaming jimmys
Is it in neutral at 1:48 ???
Xrhydraulics Hydraulics I was manual mode shifting down gears
nice video bud but how about a fair comparision meaning camera mounted in the same spot and not reving vehicle higher with the long tubes

Tony Tapuro personally I didn’t have any issues with clearance at all. And my AFM was deleted during the tuning process

Thats kinda Unfair different camera angles. Commonsense tells you the one right in front of the tip would be more louder🤦🏽♂️👎🏽

Do you need to tune it to pass
smog and for check engine?
