Hey guys I want to straight pipe my 07 and retain the stock cats, the pipe size would be 3". How will it sound? Will it drone at all?

 

anybody have a 5.4 that is straight piped??

 

straight pipes will sound ok but not good, if you just want loud its good but daily driving wont be fun. if you get a cat back you will be better off. i have an edelbrock sdt (saleen edition) cat back and it is nice, loud when you want and fair when you want (cops) i only paid like $180 on ebay (new)

 

Just do it and see if you like it. Should not cost but $20 at a muffler shop.

I put a Thrush muffler on and no piping at all after the muffler. I got the Thrush at cost from a friend. $25+tax and I installed myself. I think it sounds pretty damn good

 

I found a borla cat-back, How do you all think this would sound? Here is the link:

Stainless Steel Cat-Back? System | 140136 | Ford F-150 5.4L 8cyl - BORLA - The World's Most Winning Exhaust

 

it looks nice but also not cheap, check this out (since you seem to want single pipe)
YouTube - MBRP SI/SO Exhaust system - 2008 Ford F150 one is on ebay for $377 buy it now price

 

my 04 5.4 is straight piped, sounds fantastic, i turn off the stereo just to hear her pull the hill, or echo in between buildings or off barracades...but if i let off the throttle, hardly audible, never even had a cop give a warning for noise, had it done 6 yrs ago...

 

Sounds crappy in my opinion. But, everyone is different.
