Wow! I took my truck to get it's inspection and my mechanic said my catalytic converter was going. MY truck is 01 1500 ext cab with 124000+/- miles on it. Said it be around $750 installed. I told him to hold off. I called the dealer (just for laughs) to see they want $850+. Am I wrong or is it bolt on bolt off? I called Napa and he quoted me $480.00 oem. I'm thinking of doing it myself. I loked in the book and it all didn't look that hard. So my questions are 1- Those of you who have changed it how bad is it? any special hints to make it go easy? and last How come the dealer won't offer a dinner and a movie before they "do it to you", who knows maybe I wouldn't be as shocked if they eased me into it. Any help is appreciated. Thanks

DO a Google search and see what the GM warranty is on Cats. Every manufacturer has to warranty emissions equipment (especially cats ) for extended periods that go far beyond the 3 / 36 the rest of the vehicle topically gets .

OK, so the next step is looking at the entire exhaust system, Is the whole thing shot? Do you want the rig to breath better and sound better ? There are aftermarket exhaust systems (legal ones with high flow cats) and you can probably get the whole thing for the same price as a single stock cat. I'm a big fan of Flowmaster, but there are a bunch of other great exhaust systems outhere, ad you'll feel like you are driving a new rig.

I'm kind of in the same boat. My cats are rattling and the lead tech for the dealership's service team I'm with said it could be tomorrow, next week, next month. So I'm also trying to find out if there is a way to do it myself for cheaper than the dealer. They want $850 to $1000 to do it.

For the OEM cat system for my Jimmy they wanted $380.



I just took the sawsall to the pipe and bolted in a universal cat.

 

 

 

  • Universal cat---- $45.00 (Magna Flow)
  • clamps-----------$6.50
  • Adaptor sleeve--- $3.00
  • Borrowed sawsall--Free
  • amount saved ----$316

When I called NAPA they quoted me $480 for a direct fit, I just don't know if it's easily done. It's "supposably" bolt on bolt off but it's always the case that those bolts will not come off. I repalced my duals with a stainless system after they rotted off, plus my head was throbbing after 5 years of a throaty exhaust. I'm gettig to be an old man at 28

Yea, I've run into that lately modding my truck. I tried doing my brakes myself and I couldn't get the bolts off the caliper it was so rusted/tight. The dealer had problems getting them off!

 

So thats my only worry is that I'll dive in, find bolts that won't come off, and still end up paying $600-$700 total for someone to do it.

The fix for rusted bolts on exhaust systems is , cut off wheels , sawzalls, and or torches, nothing is worth saving it can all be replaced new for pennies on the $ for labor and time spent. The key to replacing items is to always have new nuts bolts and washers and clamps before you attempt the fit, spray everything with a penetrating spray 2 or 3 times over and hour or so before you attempt to remove anything. If the wench wont work , cut it. The proper tools make almost all jobs easy, and the improper tools make even the easiest job a nightmare.

Any time you are going to be taking off any fasteners that have been heated (like exhaust and brake bolts) you should hit them with PB Blaster or Liquid Wrench and let it soak in for a good 20 minutes. In the case of exhaust bolts - chuck 'em - as mentioned they're cheap enough that you don't wanna worry about stripping them or them rattling later on. As for brake caliper bolts, I always chase the threads of the caliper and the bolts to remove any shmeg and hit em with anti-seize before re-installing.

The cats on my 00 Silverado were replaced at around 300K, only due to the fact that running over a deer carcass broke the flange of the exhaust where it bolts to the manifolds. Since the flange part that broke was part of the down tube which has the cats integrated, the dealership replaced both cats (thank god for insurance) and the shift cable (broke where it hooks to trans). total was about $1100.

 

otherwise, they appeared to have been operating fine.

 

Rusty crud - PB Blaster (aka Panther Piss) or the smoky wrench :rolleyes:

just buy universal fit hi-flow cats, $90 each and perform better

 

Just from a tech point of view, I have worked at GM dealers for 15 years and in the aftermarket for 5. Go with the oem when it comes to cats. I have been burned too many times going with the cheap model. I am not trying to sell you anything, do what you will but the cheap cat comes with headaches later.

I cant compare cause my truck came with the Hi-Flow cats on it, They are Magnaflow Stainless Steel cats, MAgnaflow makes great stuff, and really helps increase the sound and it doesn't smell bad outside.

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      2015 Silverado 3500 right rear turn indicator failure

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
