#5 of 160 Huge Exhausts by okrafeet Jul 03, 2006 (6:49 am)
This applies to all vehicles...not just Chevy.   Honestly guys, what is the point of those huge, loud exhaust pipes? Especially the ones that sound like there's water in them. The U.S. has enough noise pollution with subwoofer bass and now more noise.   The reason neighborhoods are not zoned commercial is to keep a sense of quiet and calm which we all need after a stressful work day. Now, I can't walk outside without hearing a neighbor's truck roaring by sounding like a dump truck or eighteen-wheeler.   And it's now constant, all day, all night. I'm starting to hole up in my house on the weekends even though the noise comes through the walls.   Why can't STEALTH become a new thing on vehicles? This has affected so many lives in a negative way now. The sounds of nature are a thing of the past in my life.
#6 of 160 dream to beat a ford lightning by 03chevy Jan 12, 2007 (8:31 am)
does any one know the cheapest most reliable way to make a 4.8 beat a lightning? who has done it and what mods do you have. I have a 2003 4 door 4.8 arrival blue ss clone. ARE intake, magnaflow exaust, and super chips programer and i removed the MAF screen. The truck only runs in the low 15's now.

#11 of 160 Re: Hypertech III [buzzard_69] by sombod99 Apr 21, 2007 (3:20 pm)
Replying to: buzzard_69 (Jan 19, 2006 4:55 pm) First of all   Ditch the Hypertech. Deprogram your truck and sell the hypertech on ebay. Then, go to Westers garage for a replacement PCM. Leaps and bounds better than a hypertech.........truct me, i did it and will never look back. This Westers guy is amazing. The install takes 20 minutes and is so worth it I can't say it enough   Beyond that, As far as taking out a Lightning, you WILL need to supercharge your chevy absolutely..........or have twin turbos installed. Pulleys, Cold air intake, headers, 3 inch exhaust, a new cam, lower it for better wind resistance profile. After that, its just tiny steps to get you where you want to be. Whether you can take a lightning after that is up in the air. Maybe, maybe not. A shift kit is essential also. If you are looking to run a quarter or thereabouts, replacing the Z71 gear with a 4.10 will get you running. it will kill your mileage but its better than the stock 3.73 for your purpose.   I've read of people working an exhaust with a shortcut that is manually enacted. Basically, when you want to run, bypass the cats and the muffler and the 7 feet of exhaust piping. Its just a simple install upstream of the cats that can open on demand. Makes your shit loud as all getout but will make your truck run like a scalded ape   beyond all that, good luck brother................if you fall short, you can look into better heads and consider a valvetrain that won't burn out on you after a few runs. You are at a disadvantage if you have the 4.8. Obviously the 6.0 is the way to go and the 5.3 is also a better option to start with. You can bore the 4.8 out. But after doing all this, make sure you have someone that understands how to repair your truck and that you trust not to take you for a ride if you know what I mean   goodluck, and you better have deep pockets
#12 of 160 Things I've tried by chain1 Apr 24, 2007 (9:36 pm)
I have an 06 Z-71 silverado with the 5.3HO. It has 12k on it. I tried putting an S&B cold air intake, Jet chip stage one module, and Gibson dual exhaust. Power increase was nill and economy didn't get better either. Mileage got better after pulling the chip and intake. S&B cold air systems are a joke! I had to modify the intake tube, buy hardware, and use some of the factory tube seals because the kit was either incomplete or had incorrect hardware with it. If anyone wants this stuff let me know. I think I may have tranny and engine pcm issues.
