| I have a 1995 GMC Sierra 4x4 350 extended cab shortbed and I am putting it in my buddies barn to do a lot of work on it. One of the things is new exhaust. I don't really need to replace everything but I thought I just should since I'm putting on headers, one more cat for true duals and two new flowmaster mufflers and tips.(allready halfway there) I am pretty good at welding so I can do it all myself for it will be a lot cheaper. I bought flowtech headers(long) about a year ago and still have not put them on, so now would be a good time. I did not purchase a y-pipe to connect them so I thought I would just make it true dual exhaust.(kinda a all around handyman) Right now the exhaust goes from my two manifols into on catalitic converter and then back into duals with two mufflers(owner before me did that whole setup). The oxygen sensor is right in front of the catalitic converter. MY PROBLEM is that when i make it true duals there is only one oxygen sensor, so would anyone know how to hook up a second one, and where to hook it into, so the computer still reads both banks and doesn't make the truck run bad because it can't read one bank. Maybe all I have to do is splice it into the other one? don't know. thanks a lot for your help Derek | |

I have the same question as stacks about the O2 sensors. Any help on this would be great.

Isn't the plate holder molded as part of the bumper? tranny seems funky Yeah GM hasn't gotten the programming right on the 6 sp auto. curious what that muffler looking thing is at the passenger rear tire If it's smaller than the muffler it's probably a resonator and will be removed if installing a catback which again doesn't do much except increase incab noise. |

I'm kinda curious as to how involved troubleshooting an "egr system failure" code on my truckis. As the truck is pushing 14 years old i figure this kinda stuff happens but i dont wanna tear into it completely blind. If anyone has any tips or ideas as to what the most common causes are, Lemme Know! i just put a new O2 sensor in a month ago so thats not it. The damn check engine light comes on and goes off sporadically so i figured it was just the gas cap leaking but the clown at O'reilly's says this is the problem, whatever. Any Help would be appreciated.

i have a 2003 sierra 1500 and i was wanting to do something with my exhaust, possibly 3 inch straight pipes. I live in saskatoon, and i was wondering where the best place would be to go to do something like that! I just cant stand not being able to hear my truck roar when i drive, its just too quiet.
