removing the muffler

[airdahl]

I have a 4inch silverline exhaust with the muffler. Is it safe to remove the muffler. I don't want to hurt my engine. Will it give me more power or smoke?

It is totally safe to remove the muffler I like many people on here have a straightpiped exhaust it will not hurt your truck, as for power and smoke it really wont make a difference with an aftermarket muffler cause they are normally straight thru mufflers but it sounds better in my opinion with a straightpipe

You be fine with no muffler and this is how it will sound
YouTube - Powerstroke no muffler
YouTube - Powerstroke start

removing the muffler is probably the next best thing to slice bread

this is kinda off topic but someone told me adding 4" stacks made him LOSE 2 secs of his 1/4 mile time. My bs meter started to twitch but i didn't know cause I havent installed mine yet. (mbrp stacks still in living room floor)

2 seconds? ha, i would have laughed and walked away. theres TONS of people running stacks or even a stack. 2 tenths and maybe i would have listened for another minute or 2. but 2 seconds? no way

Theres no way he lost 2 seconds going to a stack. Must have been having a bad day

[Matt P]

yeah there is no way he lost 2 seconds with adding stacks thats just not possible, something else was the reason for the lost two seconds
