The original plan was to do LT Headers and Full Exhaust but after watching videos on installing headers i decided my DD didnt need that type of modification haha. I enjoy doing it myself so i would want to install the exhuast but the more i read into it welding is difficult when it is still on the truck and the process to get the exhaust back in as one piece seems difficult.
I just purchased the Airraid MIT intake tube for my 2011 Sierra 5.3l and noticed sounds and power immediately after replacing the restrictive and oddly designed stock intake tube. I am looking to also maximize the exhaust and am not sure if i should just replace the muffler with a better flowing one or replace with a cat-back exhaust. I am looking to save money and with just a Intake, Muffler and Diablew Tune i do not plan on having too much HP. Will the stock Exhaust pipe size be large enough? Is there any way to easily install myself or would it require welding. Attempted to find online but people seemed to offer different piping sizes for different years and engine sizes. If the piping is 2.75" as some say, would a 3" in/out muffler fit over the exhaust tubing?
I recently purchased a 2011 sierra 1500 5.3l Z71 with Trailer Package. I noticed some wires just behind the e-brake and wasn't sure what they would be used for? i assume i have a brake-controller for trailer as i can set trailer brake gain. Any suggestions one what this might be? Everything appears to be stock within the cab.
I was looking for information on long tube headers. I have a 2011 1500 Sierra 5.3l Flex Fuel with the trailer package with increased intake. I have a tune i can use through Lew and cant decide on getting Long Tube headers or not and if it would be worth the hassle. My Truck is a daily driver and i use it on the highway a lot. I dont want to lose torque but would like to get some decent numbers and feel like the stock headers and exhaust are restrictive. Does anyone know the performance difference for just having a exhaust compared to having exhaust and headers? Also would want to keep it below 1400$ total. When removing header bolts is it common to have bolts break?
I am also interested in this, i have seen 33" tires on 3" lift (2011 Chevy) and he explained he had to cut back the front fenders to fit them (Mickey Thompson Mud Tires) I would love to put 33" on mine but cant stand rubbing. I see some people say 33" fit and some say they wont. I have a 2.5" lift and it looks as though i barely have an inch between tire and wheel well in the front. I am running 31" ATVs on 17" stock rim.
I am also interested and have a very similar set up already. Sierra 1500 2013 with 2.5" lift and 5.3l Engine. I have put the tune on and deavtivated the AFM. next year i am wanting to install new Long Tube Headers, along with a full Dual exhaust. Thinking 2" exhaust to increase flow but not eliminate the Torque. after the mods i will have it tuned for 91/93 using diablo custom tune hoping to get close to 400hp or close to 340rwhp. I know with the FlexFuel engines the injectors can handle up to 400hp. The non-FlexFuel would need new fuel line and fuel injectors i believe. If you have made any mods please lmk!
I recently purchased a 2011 1500 Sierra SLE with Trailer and Tow package. I have the 17" Rims. and tire size is 265/70/17. My truck sits higher then my 2002 ram 1500 SLT 4x4 with 33" tires and leveled. But the suspension parts do not look much newer then the rest of truck. I also believe i have rear husky wheel well liners but not sure if there is a way to tell by looking at the outside (Without trying to remove them as they are tight fit) i would like to eventually put 275/60/20 (33" tires) on truck and would imagine i have clearence. but i am just thrown off by the ride height of my truck. It has no noticeable modifications that i am aware of. Also on Ram Forums everyone loved Pacesetter long Tube Headers. Anyone have advice on LT Headers that are not more then 400-500$? I am trying to search for post related but having a hard time.
I recently (2 weeks ago) Purchased a 2011 sierra SLE with the 5.3l. do ALL 2011+ have the updates? or is there a certain Serial Number that indicates if it has the updates? Own a ram before this so new to GM but excited about building it up. Looking to get Diablo Tuner, then upgrade with LT Headers and exhaust system. Still learning the site so if there are any general (To-Know) forum or post please direct me in the right way. Already looked into removing Wheel Well liner and rear lights to clean out any dirt.
