looking to put exhaust on my 04 fx4 cant figure out what flowmaster series to buy. does anyone have a video of their truck running that knows what series they have so i can hear it??
yeah i was just looking at a few on their and like what i hear from the few crappy video's i saw. my other question is what size is the stock exhaust pipe on the 05 5.4's?
Pipe size is 2.5"
Flowmasters have a kind of weird noise at full load at higher rpm.
Magnaflow's are deeper and cherry bombs are louder. I'm taking my 40 series off for a cherry bomb I think...
