5.4 straight pipe

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?

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

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...
