#292 of 340 Re: NewGuy with 1997 Silverado C1500 Questions [tbdomenz] by dlovesb Dec 05, 2007 (7:09 pm)
Replying to: tbdomenz (Dec 05, 2007 9:07 am) Hi TBDOMENZ. I have a 1999 siverado z71 4x4 with the series 40 flowmaster.I had the exhaust installed at a muffler and brake( actual name) shop. It starts at the cat and flows into the flowmaster single inlet then splits into two 2 1/2 "pipes from the single outlet that are angled out the back behind tires. The tips are rounded stainless and are over 12" long each. This shop also installs the magnaflow but agreed with the flowmaster as the loudest. I love overpasses and the Boston tunnel! The cost 500.00 installed and garranteed.Performance is improved or at least I think it added pep. You can got to the flowmaster website and hear all the mufflers for yourself. If you want even more power and sound , remove square airfilter box right out of truck. Replace with an airhog square filter that will fit like any other one and zip tie the filter in place. Face the filter down and let the air from the bottom of the truck under the hood blast into it! I clean the filter about every 3 months with the cleaning kit that you only buy once. it gets about as dirty as it would in that big box but with the entire surface of air getting in it!

remove the restrictive screen on the MAF with a dremel and watch the air flow.

Replying to: simmons4 (Dec 12, 2007 7:11 pm) Yep thats the DRL. You can temporarily disable them by depressing the dome light switch 4 times. It will come back on with the next startup. There is no permanent off switch.
#300 of 340 Vortec Max 6L rough idling by canw Dec 19, 2007 (8:07 am)
I own a 2008 Chevy Silverado LTZ with the Vortec Max 6 Liter engine. This truck is a 4x4 regular bed with about 3500 miles. When the truck is in gear but stopped (ex. at a stop light) it idles erratically, going up and down several hundred rpm. Then when we're underway, it runs fine. I've had the dealer service guys check it and they tell me everything is within the computer specs--it's just the way the engine was designed. I contacted GM and they tell me the same thing--"it's just the nature of the beast." Anybody else own one of these and experience the same kind of problem?
#301 of 340 What brand of rotors / pads should I buy? by topsail33 Dec 22, 2007 (2:59 pm)
Hi all. I have a '00 Silv ext. cab 4x4, 4.8L auto, with 95k miles.   The parking brake shoes are shot, and the rear rotors look like they're in need of replacement. I had all my rotors turned back around 45k miles.   I was wondering if anyone had comments about Napa-brand rotors / pads? They are the closest parts store to me, and I like them. If not Napa, what would you recommend? OEM ? This is a truck that gets little-use, so I don't need any HD or cross-drilled (over-priced) stuff.   Thanks - Mark Replies to this message: dlovesb (Dec 22, 2007 4:02 pm)
