2007 Lt1/5.3/3.73 -> RE: '07 Remington Edition..EXHAUST (8/25/2007 2:15:19 PM)

Hey remington, I just purchased a 07' siverado with the 5.3 gas motor and am starting to look into preformance possablities, I talked to the dealer and a local exhaust shop that i have used in the past who is known for custom systems. 1st of all the dealer told me if i replace the exhuast it Would void any exhaust related claims, but i doubt that would ever be a issue, secondly the muffler shop suggested a CAT BACK system by Megaflow, basically they would replace the muffler with one that crosses the flow from side to side and then split into dual pipes, he said that there are O2 sensors in front and behind the catalitic convertors, and that ya dont wanna remove them! he quoted me around 375$ for the system, I am guessing you have chevy's cat back system which sounds like the Megaflow system, you might find some true dual system out there but Id be prepared to pay the big bucks and your truck may not run well after that!, if you do id be willing to buy your chevy cat back system?
