Good evening everyone. I did searching and think I may have my answer, but just want to confirm, and see if I could get any opinions. I have a 2016 with 6.2, and am looking into swapping the exhaust. After looking, I'm considering swapping just the muffler on it to a corsa touring muffler. The touring muffler I'm looking at is 3 in 3 out. Would this fit my truck?

 

I believe the trucks are 3.5 in and 3.5 out, but the stock muffler is 3, is this correct?

 

Anyone who may have done this on a .2, what are your thoughts.

 

I really appreciate any feedback and answers.

I have a 6.2 and I believe all 6.2's are 3.5 inlet and outlet.. so no that corsa that your seeing won't fit direct..

Depends on the truck.... the 6.2 trucks are goofy for 2014+..... the outlet is 3" to the flapper valve. The inlet on my stock one was 3.5" as they all should be..... some of the crew cabs neck to 3" and just stay at 3" all the way to the tip of the tailpipe.

 

Easiest solution.... crawl under your truck with a caliper and measure the inlet and out at the muffler.... then you know.

For reference that was my stock catback I took off the truck when it was brand new.

On a 6.2L crew cab here is the way it goes. From cat to right in front of the muffler, the pipe is 3 1/2 inch. Except for the place where it is flattened for clearance around the crossmember. Right before the inlet to the muffler, it necks down to 3 inch. The outlet of the muffler and flapper valve are 3 inch and that is welded to a 3 1/2 inch tailpipe through the resonator and to the tip of the exhaust pipe.

 

On that note, if anyone knows of a stock muffler that is 3 1/2 inches inlet and outlet that would fit in this location, I would like to know about it. Good luck with your exhaust choice.

Not all 6.2 crew cabs.... if any as almost all I have looked at have a 3" tailpipe and resonator. I took pictures at a dealer lot last summer and posted them showing this. In fact in this body I have never seen a crew with the 3.5" resonator and tailpipe from the factory... only double cab trucks like mine pictured above. Makes no sense as the double cab standard bed and crew short are the same exhaust system lol.

For reference that is a 5.3 trucks tailpipe.

1994Vmax is correct. My mistake. The 6.2L trucks have a 3 inch tailpipe from the resonator to the tip. Nice digital caliper. The only reason I can figure for the different size pipes and muffler are for sound resonance in the cab.

Could very well be. I just thought it odd guys saying they can tell a 6.2 truck by the tailpipe... I know with the crew cabs I sure can't lol. That 1/4 of an inch increased diameter isn't particularly noticeable.

At that time the HD gas pots were the only 3.5" tailpipes on the lot

      OCI, not when but why?

      By PunchT37 · Posted

      When I was there, most to all did not have an hour meter. They just did 5000 miles on regular vehicles and 3000 on police stuff. The modern oil change monitors should take into account engine hours, weather, etc. I don`t use the monitor on my stuff. I pull the stick, look at it, smell it, rub it between my fingers, etc. That`s my oci.   I have had many engines. Some bracket race. No problems doing things my way. I was in the mechanic business for 30 yrs or so. I still do things the old school way. Don`t care who laughs at me.   Understand, I was in the main shop. We didn`t do oil changes or tires. We had a service station for that. I don`t remember the hours they used for tractors, lawn mowers, etc. Something in my head says 250 hours.

      I don't know how far back vehicles had hour meters, be it driver accessible or diag accessible but was wondering if there was any rule of thumb your shop came up with in regards to an hour limit on engine oil regardless of the miles on the oil.    I know with construction or farm equipment its almost always based on engine hours for maintenance scheduling as no other metric really applies other than a seasonal time limit that one self imposes on items like engine oil.

      I'm not sure what to say on that mess but I will say that is an odd thing for that mechanic to speculate on as per assuming its been run out of oil a few times as the odds of that engine having instead piled up with a complete seizure would be very high if such events had actually taken place. However there is nothing saying that the oil has ever been changed although once again, what filter was on that engine as that would tell part of the story if its possible to figure out if its a factory installed filter or not. Too many items unknown and a lot of speculation, but regardless of that its one fubared mess that is mind boggling to see for a vehicle that new and its hard to imagine how it ever made it that far in life looking at the top of the engine.    His scanners, I've watched him before here and there and I'd have to say if I recall correctly that some of his scanning equipment is one or two steps up from a child's Exo Sketch 😋

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      CLASS ACTION SUITS?  Does anyone know if there is already a class action suit for the paint - which was to have been fixed, changed in after the 2020 GM vehicles?  Does it look like this?    Just started 3 weeks ago - No help from GM as of yet - Dealer will not assist in speaking with GM on my behalf. Confirmed it is the paint they use along with the way the put it on that causes it to fail.  Clearly a Manufacturer's Defect.
