Muffler Position, Does it matter?

[Swans.2000.3500]

Just like the title says does putting the muffler in a certain position change power or sound? For an exaggerated example should I put the muffler just downstream of the y-pipe or should it be right before the exhaust tips?

Putting it under the cab will make it louder in the cab and more likely to drone...not sure about performance

Mine has 3" straight piping all the way to about the rear tire, then cut. Seemed to open up the engine quite a bit when I took the cat off. Stock headers and Y-Pipe.

Ill be running LT headers w/2.5" collector, 2.5"piping to y-pipe, then a single 3" out the back with a spintech 6000 on a RCLB

Usually the farther back you put it ( towards the tips ) the louder its gonna be.

I don't want it to pop like a glasspack so what position would be ideal

 

[am92]

I think you'll be fine with the spintech, but I'd say factory location is a pretty good bet

and for the single piping should i go 3" or 3.5"? I hear people are running 2.5" dual=9.82 sq.inches and a 3.5" pipe=9.62 sq.inches

I'd go with 3" single...I know a lot of people (myself included) run 2.5 duals, but on a stock truck 2.25 duals are probably better for exhaust velocity

Alright one last question, is a DI/SO just as effective as a y pipe and then a SI/SO
