2000 f150 5.4 Lariat. i have true dual 2 1/4 inch x pipe with 3 1/2 inch tips. two rear cats removed. how can i make it louder? i want to keep the x pipe
in. thanks to everyone who answers.

 

what type off muffler's are you running?

 

take your muffler out if you have one, or the front cats, and if thats still not loud enough, longtubes, no cats, and no muffler....

 

front cat delete wont do much, depends on what mufflers your running.

 

im not runnin any muffler

 

I think the only way to get it louder is LT's or no cats at all

 

sorry..but what are LT's..

 

long tube headers. Either buy those or remove all your cats. Your truck really isnt loud enough for you? I have a 3" bullet with all my cats, CAI and its loud as hell.

 

Pfft! That's not loud.


Removing the small, front cats is about the cheapest/easiest thing to do right now (seeing as you want to keep the X-pipe)...

Replacing the X with an H pipe, or running no crossover at all would make it louder as well...

 

ok but will removing them mess with me engine or cause problems? it the cel dont come on ill just take them off

 

CEL will come on if you aren't running converters, and it will run like hell until you custom tune it.

I kinda figured you have no mufflers judging by how you did not list any in the original post. I would make the exhaust exit before tire, but unless you have the few hundreds for Longtubes, give OBX a call and get their $500 stainless set on order.
