alright guys i have a 99 f150 with pacesetter longtubes and highflow cats true dual with a set of race mufflers on each pipe than exited 45 down with tips out behind the tires.. the pipe is 2.5"

I was wondering if i put a x pipe in there would it give me the low end i want? or would it not matter?

idk if i am not gettin enuf back pressure or what.. It is still fast just not on low end...
idk what it could be..
if you have any other ideas let me know
thanks for the help

what race mufflers? and do u have any sort of crossover? yes, the X pipe will help without a doubt. 2.25" would have been a better bet, but no going back now haha.

 

The X pipe will help balance both engine banks velocity to level out a proper scavenging level for your true duals. Keep it as close to where the OEM Y pipe was as possible.

sorry guys when i wrote this i wasnt thinkin i do have 2.25" pipe and i will put the x pipe in there just like darren said thanks i appreciate the help.. i just bought a edge programmer also wow its a new truck i just want more low end...
thanks

what race mufflers do u have?

 

flowsound race muffler its a one chamber flowmaster muffler with just a backwards v in it.. i went from true dual to that and it was a huge difference also they sound GREAT! loud!

 

went from what to what?

 

from true dual with cheapo napa mufflers to these..

 

Chambered mufflers do not equal good performing mufflers.

 

2.5" true duals are overkill, 2.25" would have more low end.
