  1. Just for clarity- 3.5" is the diameter at the end of the y pipe? Thanks for the suggestion on MBRP, I just checked their site and unfortunately they don't have any pre-set systems for the 6.2 (They have 4.3/5.3/6.0) However when I bump the year to 2011, a few systems pop up. They do specify 3-1/2" Exhaust as well. What changed between 2009-10 and 2011- I have an easier time locating systems for the 6.2L if I filter from 2011 and up (most places don't offer any 6.2L systems until after 2011 Silverados)
  2. Hello Everyone! Before I get started I want to thank anyone in advanced who responds with pertinent information. I'm looking for a replacement exhaust system for my 09 Silverado 6.2L 4x4 Crew Cab/Short Bed. My current system has lots of rust (living in MD, they heavily salt & brine the roads here) and has sprung an exhaust leak right behind the muffler on one of the pipes. I've been searching around (thought it would be easy to find a system) but have not had luck in finding what I have been searching for. There are plenty of systems for 5.3L & 6.0L motors but scant any for 6.2L. On my truck currently is an aftermarket cat back system that was there when I bought the truck (not sure which brand.) It is a single in / dual out muffler with dual pipes going out the bumper. Questions: What is the factory flange diameter at the end of the factory Y pipe? I'm seeing conflicting information (this will help me determine what muffler to buy if I piece meal a system together) If you have any suggested systems, here's what I'm looking for Material: 304L Stainless Steel Volume: Loud/Agressive Configuration: Dual exit at rear bumper I'd consider a long tube header setup w/ high flow cats as well (I would like to maintain all emissions equipment) any suggestions there are also welcome. I can always get a quote from a shop but I wanted to shop around first before I did that.
  3. I called my dealer today and they told me they don't do it for consumers. I'm in South West AZ. Per the Service specialist they only do it for government vehicles and then they have to fill out a form to get the BCM flashed. Here are some other posts I've found regarding the BCM flash. https://gm.oemdtc.com/4610/bcm-calibrations-to-restore-bulb-outage-detection-turn-signals-flash-fast-2007-2016-chevrolet-silverado-gmc-sierra <- GM Tech II info on BCM programming options http://www.dieselplace.com/forum/76-speciality-forums/81-electrical/573585-reprogramming-2007-bcm-led-lights.html http://www.duramaxdiesels.com/forum/showthread.php?t=55843 <-Best thread with most responses http://www.silveradosierra.com/electrical/dealer-reprogram-bcm-for-leds-t245442.html <-Some references to BCM flashing http://www.gmfullsize.com/threads/led-hyper-flash-2500hd-custom-bed.278672/ <- This dude built his own flatbed with LED's, and was given info on flashing the BCM. I found a technical bulletin for these year trucks, hopefully it helps https://www.gmupfitter.com/files/media/photo/734/UI%20Bulletin_81c.pdf And the website where I found it https://www.gmupfitter.com/pages/technical-bulletins
  4. That's how I had it initially configured. It won't hyper flash when the DRL lights/low beams are off. As soon as I turn them on the hyper-flashing begins.
  5. Hello everyone! I wanted to upgrade my rear tail light bulbs (not the entire taillight assembly, Just the Bulbs) with LED's. I purchased a pack of 6ohm 50 watt load resistors. Vehicle: 2009 Silverado 1500 LTZ, 6.2l Upon removing the drivers side tail light from the housing, I found the main part of the harness has 4 wires before dumping into the lower blinker light: Green (reverse light) Yellow (upper blinker) Brown (lower blinker) Black (ground) After wiring the load resistor to the brown wire and a separate resistor to the yellow wire, I decided to test them with the LED bulbs installed. (Note, no led for the reverse light, stock bulb.) With the DRL Lights off, the bulbs blinked normally. Upon activating the DRL Lights, the bulbs would hyper-flash after 3 normal blinker flashes. I tried relocating the [yellow wire] load resistor in-between the upper blinker and the reverse bulb but had the same results. Also worth noting, I tried removing the resistor from the yellow wire and the result was continuous hyper flash regardless of DRL lights on or off. Anything I'm missing? Thanks in advanced.
