was bored and was throwin around the idea. anyone do it? are there any negatives? Gas millage? Backpressure? power?

I had only cats and no mufflers on my 99 5.4 F150 and sounded good and had no problems

sounds too farty and unclean is what everyone says. atleast get some LM2's or race bullets or something. they don't really muffle anything they just help clean up the sound instead of strait piping it.

Yeah, don't do this lol. More than likely it'll sound like crap.

I have a buddy with a 2006 gt, with a catted h, and muffler deletes, and it sound terrible imo.

Will it be loud... yes! will it sound good...no! And as far as the other things i dont think they will be affected much at all

dStuck

well i tried it just cause i had nothin better to do. it doesnt sound bad. lust louder and deeper. my buddy said it doesnt sound too different from outside when i passed him just slightly louder and much deeper. inside it is a huge difference, but it's also dumped after the H-pipe and is right under the cab.

i'll prob. run it like this a little while i replace all the rusted bolts. and stuff underneath

Which you running around with??? H or X??? Id say that the x would probably be raspy as hell and the h i dont think would sound too terrible. lol so i dont see a problem with it. might try this myself someday soon with the catted x.

Id just keep the mufflers...mustangs don't sound well without them...i think anyways.

This is a bad idea..

i have the stock H. it sounds pretty much the same as my magnaflows just louder and deeper. not really more raspy or anything
