I am wanting to get exhaust put on my husbands 2005 GMC Sierra 2500HD, but I want it to sound good, Im thinking straight pipes from the converter back, with 3 1/2 to 5 inch tips anyone have a better suggestion. We like em loud!

5" tips!? Is it a diesel?

 

long tube headers with 3" open exhaust all the way to the bumper.

 

Actually, 3" exhaust from the cat back would hurt performance. You could go for a 3" in/dual 2.5" out Muffler of choice, and run 2.5'' out the back with 3" or 4" or whatever sized tips you want.

 

If youre wanting to go straight pipes, you could get a Y pipe thats 3" in after the cat (i think the stock size is 3" up to the muffler) and 2.5" out and run straight pipes out the back with whatever tips you want.

3" in dual 2.5" out sounds about right. Just a bit bigger than stock without losing backpressure, if that is concern. If not a concern, the mid range could open up with headers, true dual 3" in/out all the way back.

 

 

Go street legal headers if you can find them for your application. Try JBA Headers.

 

As far as muffler, I have been satisfied with Magnaflow for years now on all my vehicles. I like the low deep sound and open design Magnaflow has brought forth. Borla has a good sound, I don't know if they make them for your application. Also check Dynomax.

 

Check with TBryne, a sponsor here, he handles better than decent performance products at decent prices. I was just researching the products last night that he deals with for a buddy of mine that has a SRT8 6.1 Charger. He's been good with the F-Body crowd as well. Definately has a good name out there for himself. Then you would have to find an installer at your choosing.

 

Good Luck! :)

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
