Well until i figure out which exaust i want to run..and get some money next pay check... i couldnt stand having the muffler on my truck anymore. So i cut the muffler off and welded in a 3 1/2 pipe in its place... and i must say it was LOUD.... Almost too loud! My question is.... is removing the stock muffler Realy helping anything other than making it a big noise machine??? I dont have Guages yet so i cant tell if my Egt's are lower or not. Im running a sniper chip on the 100hp setting and i dont want to tear anything up. Guages are on the way and that sniper is out the door.. Going to look into a DP Tuner! Anyone know anything bad about taking out the muffler?
