I have a 2001 Silverado ext cab Z71 with the 5.3L. I bought the truck last May and in two days put on a K&N FIPK and replaced the muffler on back with a 3" Flowmaster and non-mandrel bent pipe. Don't know if the exhaust work gave any gains but it sounds good. Any other low buck or free mods? It's my only vehicle and down time must be very minimal. Thanks.

Yelo

Do a search for "free mods"...it'll save you alot of time and alot of flaming from those of us that have typed that list 500 times......
