Carburated 1987 3.9 V6
What would be the best kind of muffler to get that could use the exaust setup i mentioned above that will possibly increase power, and what about a small set of glasspacks? would that give any more power and sound good or not
it will run without the muffler but... you will loose hp. take the cat out, put in 2 and 3/4" piping and and magnaflow or dynomax muffler on it

glasspacks are loud on the 3.9, my truck came with one on it, no cat and it exits the truck inbetween the cab and the rear tire on the pass. side. its load as F***.

What specific kind of spark plugs you think would be the best?,and I do plan to use the A/C but im not sure if it works, it cycles on and off but it needs to be recahrged, and what about changing the exaust system, i was thinking of taking the mufflers off if a 3.9 V6 sounds good and then have the pipes go strait from the engine and having it coming out about a foot in front of the rear tires though thats if it will increase any power and/or tourque but i still want to hear what others think could be done

at first they do untill all the "glass" gets burnt out of them. im going to do and exhaust on mine but putting a new glass pack on it and exiting the back of the truck.
Some one i know told me about a product you can get that can increase power and increase MPG that you put in the air intake system that supposedly speeds up the air flow by forcing it into a spiral path and it flows faster though has anyone tried one for either of the engines and if so does it work or not, I think its called a Tornado Fuel Saver or somthing like that
