I have a 2012 GMC Sierra 1500 with 2.75" exhaust pipe. I am wanting to delete my muffler and add a glasspack without welding. Problem is, I can't find any adapters to fit anything. Do I go with a 3" or a 2.5" glasspack? And whichever one I go with, what size adapters/reducers do I use? The muffler shops in this area charge around $350 for this work, so that's the reason for doing it myself. I appreciate any help given!!

Issues with my 2012 Sierra
rob1231 posted a topic in 1999-2013 Silverado & Sierra 1500Hey all, hopefully somebody can help me out here. This past summer i bought a new Sierra extended cab SLT, and it seems all I have had so far are problems. I purchased the truck from a reputable GM dealer near my hometown. The truck was listed as a demo, the only driver being the actual owner of the dealership. I saved a good amount off the original sticker price for only having about 18,000km's on the odometer. ISSUE #1 - HISTORY I purchased the truck on July 7th 2012. I noticed on August 4th 2012 on the front drivers leather seat was beginning to "ripple" if that's even the correct terminology. I gave it a few days to see it it would "tighten up" after giving it a good clean up and conditioning the seats with the dealer provided solution at the time of purchase. I took a photo of the seat on August 10th 2012, a few days after noticing the damage. Nothing too serious, but beginning to bug me a little, considering I had just spent nearly 40K on a vehicle that I thought was well built.. I contacted the dealer I purchased my truck from and talked to the sales person whom I dealt with directly on August 13th 2012. I was told over the phone that leather on a truck this new would not let go this easily, and that I may be over exaggerating the problem. I brought my truck in the following day. I got a big story of how they had never seen such a problem on any vehicle, let a lone a vehicle this new. They continued for a little while and eventually handed me over to the service department. Service department told me it was an easy fix by re-tightening the leather from behind, a two hour job at most. I ended up getting scheduled for an appointment a few days later. On the day of my appointment I was told the upholstery person was too busy and they would give me a call when the situation got better to reschedule my appointment. October 23rd 2012 - A few weeks later, I was able to get the truck in for them to take a look. The service department wasn't able to fix the seat and would require ordering a new seat cover from general motors. November 13th 2012 - 3 weeks have passed since I was last at the dealer. The cover came in and truck was in for replacement. Job took about two hours. I was given a car for the day and came back in the afternoon to pick my truck up. (sorry for the blurry photo!!) Tonight (December 12th 2012) Second seat cover, same problem only worse. Keeping in mind, I'm a pretty small guy, so I don't think this is a weight issue by any means. The first time the dealer was unwilling to replace the whole seat, or even the bottom section. I almost fear that's what is needed in order to fix this problem. What to do? It almost feels as if the seat cushion is sagging underneath. I have never seen this on any of these trucks, sadly only mine ISSUE #2 Transmission is starting to slip when accelerating between 2nd gear and 3rd (its the 6 speed, 5.3L). This truck has just reached 40,000km (about 25,000 miles). Its hard to pinpoint it exactly, as I've only started to notice it at the beginning of this week. Please don't tell me its "just the way those transmissions shift" its not, i know it isn't. I'd hat to run out of warranty on my truck and all of a sudden left stranded with a blown transmission on the side of the road, and kicking myself for not taking action as soon as I noticed it. Any help and guidance with either issue will be greatly appreciated.

MrBooger posted a topic in New Member IntroductionsWhat's up folks! i signed up after reading an amazing thread on upgrading the stereo of an 06 silverado. I got a lot of good info from that. I am the proud owner of a 2012 GMC Sierra CC Z71 SLE. I really like the truck but it has a few "quirks" that are just annoying. First, when cooler outside, when the truck is completely cooled, when taking off at a descent acceleration, we'll say 1/2 throttle, shifting from 2nd to 3rd it does what GM describes as a "flare". it is almost like a slip but not an actual slip of the tranny. More of a long, slow shift. They say it is normal, as i had the 2013 loaner doing the same thing in no time. GM actually had my dealer take 5 new trucks off the lot to test. 3 of them did the same thing. it only does it once, but is still annoying. 2nd, the freeking headlights/dome lights. My headlights flicker when both at idle and driving then the a/c compressor kicks on/off. domelight when at idle dims when you press the brakes...they also say this is normal..whatever.. But i do love the truck! So far i have only tintet the glass and upgraded the headlights to Sylvania silverstar ulras. BIG DIFFERENCE! i'm not a big fan of the HID's, so i just went with a bulb upgrade. I want to toy with the exterior lighing, maybe some led lights and such. Mainly i am wanting to upgrade that weak stock stereo. It is the non Bose system. After some of the reading i have done, i will probably keep the stock head unit, and for now just add an amp (probably the pioneer gm-d8604) mounted on the rear wall behing the rear seats powering the Alpine SPR 60C components up front and Alpine SPR 60 in the rear doors. I have read in a few places that the 60C's tweeters will actually fit where the stock tweeers are located. I really hope that is the case, i really dont care to drill holes in the truck. Maybe one day add a sub, but im not too much worried about bass. i mostly listen to rock and dont want any sounds drowned out by excessive bass...plus im too old for all that crap now. Any ideas or tips? I'll be doing the install myself, eventually...The boss/wife kinda has a hold on my spending for now..
