I have a 2015 Sierra with a 5.3. I've been running it with a K&N intake and corsa sport catback for over a year now and been very happy with it and the sound. I am planning on getting the truck tuned soon and wanted to get the most out of it so I installed a set of Texas speed longtube headers with catted Y pipe. Now the truck is WAY too loud. Just wondering what my options are and if anyone else has run into this? Would switching the muffler over to the Touring style help? and if so how much?  I'd really like to keep my catback and find a different muffler that would bolt into its place without having to do any welding or anything. I expected the truck to be louder but this is ridiculous.  I did some research but couldn't really find the answers I was looking for. Any insight will be greatly appreciated.  Thanks

Get hold of the touring muffler and switch it out, it's exactly what I did with my Silverado.  You'll be impressed with how quiet it is with the headers.

I didn't see anywhere on their site where you can buy just the muffler. How did you obtain yours?

If you email them with your situation and proof of purchase, I believe they will sell you just the muffler or keep searching for a used one.

Haha, traded with someone that had a touring with stock manifolds.

I have the GM cat-back exhaust that comes on the All Terrain X models, which I believe is a Corsa Touring muffler.  I might be interested in trading, so long as everything fits right up.  Let me know.  I'm in NY, so we would have to ship.

Just wanted to post an update incase anyone else runs into the same issue. I was able to get a corsa touring muffler and swapped it out for the sport. The truck is MUCH  more bearable now and sounds good. I'd say it's still louder than having just the corsa sport catback, but it sounds very good. Can keep it quiet when you want, but when you open it up it gets very aggressive. Very minimal drone at all but more "ticking" noise now since installing the headers you can hear more of the valvetrain movement which is expected.. Overall very happy with the setup and have gotten many compliments on it. Current setup is tsp 1 7/8" longtubes, high flow catted Y, corsa touring catback, and k&n intake with a custom dyno tune.

Did you notice significant increase in power with adding headers?

Yes I did. Seemed to pull harder through the top of second and third gear but the real noticeable gains came after getting it tuned.

Do you happen to have any videos of the corsa sport and tsp headers? 

No I don't...

      I know; crap pictures.   Anyway, as a finale of sorts to this thread, I had replaced both differential covers and since they had the capability of adding temperature probes, I did that. These are MaxTow analog/digital gauges with stepper motors. They'll flutter around like crazy for a moment and start at a nominal 100 degrees Fahrenheit.   I drove a 30-mile loop to the grocery store, averaging 70 MPH (as much as 80 to see if there was a quick spike in temperature. The air temperature is 102 (ambient ?). but the first pic is 7 miles into the trip. The second is getting back into the truck after leaving the store; differential temperatures dropped about three to four degrees in 15 minutes. The third pic in on the road to my house, about a mile away.   In that run, I saw a high of 150F on the rear differential, and 121F on the front. I'm sure a longer drive or towing will see higher than that, and when that happens, I can update the observations.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Fully warm, coolant temp >194, closed loop.   Run time can be anywhere from just reached operating temperature to having driven 30+ miles.   The O2 chart (which is a feature I just discovered after reading) for the bad idle seems to be "most" of the time. For the little time I've been watching it (scanning and driving! watchout!) I can't seem to isolate any cause or condition yet.   It definitely idles rougher sometimes than others and so far what I've seen is the rougher idles are always rich. But not enough to set a CEL.   In other news I replaced the starter solenoid. Everything on this truck is such a PITA. Starter "snout" is mangled up with the torque converter inspection cover which is tangled up with hard cooling lines and the driveshaft. But I got 'er done without too much swearing...I just go into everything now knowing it's going to be a frustrating mess.   The starter solenoid replacement kicks off the next round of work: AC, injector rebuild, cat, exhaust. I'm just going to do it all. But first:   I don't know what my fuel pressures are. I can't definitively say the issue is the injector without first verifying fuel pressures and any leakdown. I "rented" a test kit ($199.99 at O'Really's ...intentional misspelling). They don't "rent" tools anymore, they charge you for the tool and then you return it when you're done. No joke. It is listed as a rental on the receipt but the guy told me there's no difference between renting and buying  now, you just return it when you're done and they refund the credit card. Mmmkay, whatever.   I will rule out fuel pressure issues (too much), and any leaking (that's how I'll know the problem is inside the intake). I think someone said the return line could be plugged or not flowing and that could cause high fuel pressure (and too much fuel being pushed through injectors). I'll cross that bridge if I get high readings.   As of now I'm ready to tear off the intake cover, extract the injector, and have it sent off to be rebuilt just so I can rule that out.

      What are the conditions of this rich idle? Warm or cold engine? Run time? Does every idle look like this or only sometimes?
