Does anyone have FlowMaster 40 muffler on there trucks? I'm thinking of getting one for my truck. I have some knock off FlowMaster on it now and you can't hear it at all. It's on a 351 Windsor so if anyone has a 40 on their Windsor, could you post a video of it so I can hear what it sounds like? Thanks.

 

I dont have a 351 but i have 4.6L v8 with an Original 40 Flowmaster, sounds really good i think. I have no mods (ie. CAI/Tuner) just stock cats and SI/DO

clips in my profile at the bottom

 

I have the 40 on my 4.6 with magnaflow high flows...Lets just say you can hear me coming from a long ways away...If you want loud then the 40 is for you

 

40 series is a good sounding muffler. Plenty loud.

 

Good cause that's what I want. With the muffler I have on it now you can hardly hear it when you're standing right behind the truck.

 

Check out some YouTube videos of F150s with 40s.

 

nvm

 

i have the Super 44. i have it dumped right after the cab. it sounds really good. i occasionally have someone drive my truck so i can listen to it lol

 

LOL.

Well, I ordered it this morning so should be here sometime this week I'm hopin.

 

Edit, Wrong Thread.

 

sweet. You should be happy. If not, then its time for some cat work.

 

I hope not, I'm kinda tight on money now.

 

Well, put the 40 on last night and at first it was really quiet. I've put 100 miles on it today and it sounds like it's starting to burn in. Will it get much louder or will it be on the quiet side?

 

I would estimate 300 to 500 miles. I was disappointed in mine at first. After about a week, it sounded great. Loud enough to hera when you accelerate but not irritating.

 

it will get somewhat louder. what year is your truck?

Mine was better with the 40, much better when I replaced all 4 cats with 2 high flow magnaflows cats. Then even better once I dumped it right infront of the rear axle.

you could just try that. cut the pipes off and you will be able to hear it better in the cab.

But highflow cats the way to go. 80-90 buck each or something like that..

or maybe that was for the pair I forget.
