ok so hear we go got a 98 k1500 with a 350 in it. true dual 2.5 inch out the back with 90 degree tips. i got a knockoff brand of a flowmaster and its too quiet. but i get good mileage. and it dont sound to bad ideling. whats some suggestions for a new muffler for a loud exhaust. a nice tone would be nice. not too pricey if we can help it

thanks

 

Why not just get the real Flowmasters installed? What did you get Flopro's?

 

mine is true dual all the way back no mufflers it sounds amazing i have never got a complaint that my truck sounded bad

 

I have magnaflo's and they are great. I would highly suggest getting an X-pipe or something like it so that you get the added benifit of it. I am going to do this once I get some time on a lift and a welder in my hands.

 

i dont know what brand they are. but without mufflers i got ****ty gas mileage it dont make sense

 

You could try those vortex mufflers or even glasspacks. If you dont have much money then that would be the way to go.

 

I had a single glasspack on my 90 model dualed out and it sounded great. I had many people compliment me on it instead of my buddy's truck with a flowmaster dualed on it.

 

did you still get pretty decent mileage?

 

Its really hard to discipline myself to use very little throttle to save gas. The truck gets louder, the performance goes up, the more throttle we put to feel more of the performance. Drive a sleeper and we could cruise it all day to save gas cuz you dont hear the engine. So what I'm sayin is its hard to get an exact MPG with added performance. So I myself only have estimates, but I know for a fact it does increase MPG. You will notice it doesn't take much throttle to get going than it did before. So in a sense technically you should get better.

 

im still undecided about it but i want a louder truck. but when i had my truck without a muffler i was at about 12 mpg. and now with true dual with two mufflers it gets 15 around town and 18 highway so im happy
