So i cut the stock muffler off and replaced it with a trush cherry bomb. It had a unqiue sound wicth i liked but i imdeitally saw a sharp decrease in mileage. 10-12mpg. I wonder what on earth is this all about. So i did a full tune at 76 the whole package. Same kinde of mileage. I was scratching my head, then someone at work told me to put my stock muffler back on.( glad i kept it). My wonderful fuel ecomony sudenully returned. I was overjoy. I would say put your stock exhaust back on if you want ur mgp's. Backpressure what a wonderful thing.
well im sure it would prly help... but my bro took the stock muffler off when he had it. lol so i have not the slightest clue ware it is lol... but my pickup sounds so sweet for a V6... everyone says man this thing has a V6 in it i say yeah... and most the time they either say why do you have such a small engine... or wow it sounds like a V8... im not gunna lie it does... i have 2.5 inch exhaust with a 2 in 2 out cherry bomb... cant remember the name of it tho... all i can say is i have never heard a V6 quite like mine. i will keep the sound and lose a few MPG i guess
lol
thanks for the sugestions again guys!
