March 27, 2010hey guys i was just wondering if i would be better off adding a muffler to my exhaust. the guy i bought the truck from left the cats in and just cut out the muffler and ran dual pipes out the corners. it doesnt affect my inspection because i have a guy that will do it but would it sound better if i put 2 magnaflow mufflers on there, although it sounds pretty darn good now! will taking out the muffler affect the truck in a negative way? Thanks

March 28, 2010taking stock muffler off defently helps. puttin on a magnaflow would defently quiet it down and maybe give you a little more power
March 28, 2010Removing your muffler will not adversley effect performance or mileage. The engine is a thermal machine that likes to breathe- so no backpressure is desireable.
For years there have been several that say an engine needs backpressure. With EGR valves in the late 80`s that was correct. Not anymore. If you like the sound- leave it out. You should pick up some performance although it will be so slight you probably won`t be able to feel it. Usually in the realm of 1-2% max.
March 28, 2010if i add 2 magnaflow mufflers will the sound change alot?
March 28, 2010ya it will be a lot quiter...i had straights and then put glasspacks on which are almost as loud and when i did that my truck had a lil more power and i picked up .5-1mpg but nothing incredible...if u like the sound dont do maganaflow go glasspacks 12" preferably
March 28, 2010whats the difference in glass packs and a muffler? Are they expensive?
March 28, 2010glasspacks are a straight through design that just have fiberglass in them to obsorb the sound, mufflers have chambers that the flow has to go through. and glasspacks are cheap you can get em for round $30
March 29, 2010if theres not much difference between the glass packs and straight pipes i think ill just stick with what i got and spend money on another mod
March 30, 2010i would just put the one magnaflow behind the cat and run duals out.
February 8, 2011Take off them cats!! Mine has none, and you get more power and better sound.
