Hey all

I currently have a 1998 f-150 4x4 extended cab with 33's.
its got the mean look but its laking in the sound department. The gibson setup just isnt cutting the cake. im think about puttin a true dual setup on with the 40's. the only thing is that i dont know if it is worth changin the cats. Its got the 5.4 in it now. I want loud!!

 

if you want real loud just cut out the cats and get a true dual..that'll be gettin ir done

 

Yea but then the check engine light will come on. ive got an o2 sensor after the last cats. itll also run like crap.

 

Do you have headers on it? I just put BBK shorty headers and a Gibson Super Truck muffler on my 97. Its a 4.6 and its plenty loud.

 

Thats a good idea. no i dont have headers. were they something that you were able to do yourself. The only problem im having is whether the 4 cats make a difference. im kinda running on a short budget. im thinkin about what muffler. i think im sold on the imco extremes. i dont know whether i should put hi flow cats on or not would it make a noticable difference or would it be loud enough with the stockers.

 

Nah. I didn't do it myself. It's kinda tight in there, so i took it to my mechanic. I decided to do one because I blew a cat and the dealer wanted to charge me a ridiculous amount of money to fix it with the stock parts. So I said screw it and went with headers and a new muffler. I did stick with the stock cats though. Still its plenty loud. I'm not sure what kind difference high flows would make.

 

long tubes and glasspacks or single chamber IMCO's is as loud as it gets using a muffler

 

What you want to do works wonders. I already did exactly that on my navigator. I have a picture posted here: http://navigatorfourms.7.forumer.com/viewtopic.php?t=4

I ran dual 3 inch from the manifold back, with jeep 6cyl cats and flowmaster 40 series. ANd its loud, oh yeah it loud

 

hey guys thanks for the advice. i tink im just gonna keep the cats take out hte y and weld in a x pipe and do 3 inch duals into 2 imco extremes. if this does not do it i will just put the magnaflow hi flow cats on. thanks again!!
All HAil the blue oval.
