What kind of budget are you looking at? Lots of people do the basic cat back exhaust, cold air intake and tuner. Replacing the stock muffler with an aftermarket one is usually much cheaper than a whole catback system. If you're looking for more power, a cam swap and a custom tune to go with it would be a good place to start. The right cam can really wake these engines up and should be good for about 50hp Sent from my LM-G710VM using Tapatalk

As far as I know tow/haul changes the shift points and increases fluid pressure in the transmission. Not sure to what extent it would increase the life of the transmission, but it would definitely reduce slippage. The way GM set these transmissions up from the factory is straight up garbage. They prioritized smooth shifts over longevity, thats why i have a corvette servo and transpo hd2 shift kit in mine. Installing a shift kit will do much more to extend the life of the transmission than leaving it in tow/haul. Sent from my LM-G710VM using Tapatalk

I had to pull my y pipe, the nuts came off mine luckily, but i've broken and stripped studs on manifolds in the past, i've always drilled the studs out and replaced them with bolts. Sent from my LM-G710VM using Tapatalk

Yeah, none of chevy fenders/hood, etc. will work without changing the whole nose. I believe all 99-06 gmc fenders, hoods and lights are the same, 03 changed the bumper and grille. The yukon never got the facelift though, so all yukon parts to 06 should work. Not sure about a 2500 or 3500 though. The 99-02 chevys were different. Sent from my LM-G710VM using Tapatalk

Assuming you're talking about hood/fenders/grille etc, 99 to 02 should be a direct swap Sent from my LM-G710VM using Tapatalk

I took my truck to 2 different shops for an alignment and its pulled to the left ever since. The camber is 0.9 on the left and 0.5 on the right. The caster is 0.1 on the driver and 3.5 on the passenger and they say that wont cause it to pull, which I dont believe. The second time I brought it to this place (4th alignment total) they said the adjustments were maxed out, but the pull was due to me installing the pitman arm wrong, but the wheel goes 1 3/4 turns each way from center, so I don't see how that could be. They told me to fix the pitman arm and bring it back. The truck has leveling keys and add a leafs in it, but I didnt think it was impossible to align a truck with a leveling kit.

As long as all 4 tires are the same size it shouldn't be an issue. The computer wouldn't be able to tell if all 4 tires changed in size, although your speedometer would be inaccurate. That being said, you can use a tire size calculator on the internet to find a tire size for an 18 or 20 inch rim and match the stock outside diameter. You can buy a new truck with a 20 or even 22 inch rim, and those tires are pretty low profile Sent from my LM-G710VM using Tapatalk

Do the turn signal indicator lights work? Those and all the backlights are the only incandescent bulbs, the rest are leds. Seems pretty weird that all of them would be burned out like that Sent from my LM-G710VM using Tapatalk

I bought a set of oe style flares for $50 on ebay for my 03 sierra, and they fit like garbage. Im willing to spend some more money for something that fits better. Has anyone had any luck with any different ones? I know you get what you pay for, but am I going to get the same exact flares if I buy a set for 100 bucks? Im not looking to spend 130 each for OEM ones. Thanks Sent from my LM-G710VM using Tapatalk

Got one for my jeep at advance, im sure the chevy ones pretty common also so most parts stores would probably have it Sent from my VS987 using Tapatalk

Definitely fixable if you're good with a grinder and a welder, probably worth fixing with that low of mileage, but probably not worth your while at that price Sent from my VS987 using Tapatalk

Did you replace the turn signal relay with one for led lights? Sent from my VS987 using Tapatalk

https://tiresize.com/calculator/ Might want to look at a smaller size if you're at stock height. 275/55r20 is an oem size on the newer trucks i think Sent from my VS987 using Tapatalk

2wd or 4wd? I usually buy the moog problem solver parts. Theyre supposedly better quality than their other product line but who knows Sent from my VS987 using Tapatalk

I've seen plugged cats trigger a MAF code. It had no power, replaced the MAF with no change, loosened the y pipe bolts and it came right back Sent from my VS987 using Tapatalk
