Well despite all the bad talk about flowmasters I decided to spend the 200 bucks and get a couple 40 series put on. Now I'm not a human dyno but I really can't feel any difference, meaning no bad difference or good difference. But oh my goodness does my truck ROAR now! Its a nice mellow tone at idle but when you give it a little gas it comes alive! Now I can say my beast actually sounds like a beast! For those who can't afford bassani or jdm's silver bullet I would say that flowmasters really are not that bad at all! They sound very aggressive (spelling?) and deep! The only problem that I am having is that since there are 2 mufflers in a place designed for one big muffler its making things difficult. I am having clearance issues with the mufflers, they are stacked sort of diagonally but sometimes when the truck rocks up and down the mufflers hit the bottom of the truck. Not a big problem and I think I fixed it but it does get annoying when stomping on it and hearing this *thunk* sound. All and all my devil sounds a bit more evil now

 

Sounds great. For a Mod that doesn't really give us any HP to talk about $200.00 seems like a good price too, keep us up to date and good luck

got any pictures ?

 

I'm sort of a dumba$$ and don't know how to post the pictures, but I'll figure it out, its dark out now so I'll take some pics tomorrow in the nice day light!

 

HA HA HA....Hey InS0mNiAc,
when you figure out how to post pictures let me know too! I think I'm in the same boat!

 

You guys need to set up a F150 online gallery

Then you can post the pics from your album.

 

I'll try that, thanks Don.
