Hi i have a 2002 f150 ext long box quad cab....i noticed i have four cats, and i heard the o2 sensors are in the front set,,,i really want my truck to have a nice LOUD sound to it, i cut the muffler off but it is still very quiet, if you could tell me what would be the loudest way to make this happen
i can replace the sensors if i cut the cats, but wasnt sure what type of exhaust or straight pipes or wether or not to cut off all cats....PLEASE help me

 

cut the back 2 cats off and run whatever exhaust u can afford. these trucks just are'nt loud if u dont. im running duel strait pipes with my back cats removed and no c.e.l. and its loud but has a great sound.

 

i have my rear cats hollowed out with a flowmaster 44 (that might be shortened) with dual outs and its loud. in the morning i get a little nervous everytime i start it in my apartment complex. its not the loudest truck but its louder than i would like it.

 

I would but i have an o2 sensor right after the second cats or resinators not sure which they are

talked to a muffler shop, and the guy seaid if i wanted the check engine light to stay off i should buy high flow cats, i want loud as hell to start i can always quiet it down later, but im just trying to get the loud first

any ideas on high flow cats or if the back 2 cats/resinators matter, i dont want the light on, i work at an auto body shop, and i hate when people light are on lol

THanxxx

 

i cut mine out and dont have a check eng. light on! the guy is trying to get more $ out of u!

 

What did u do with the sensors. !? I wa thinking of cutting the back two and putting stright pipes with cherry bombs. Any better ideas

 

im sorry if you guys get a lot of exhaust ?'s but im so confused

will the sensors matter if removed than put back into just straight pipes not having the back cats/res

or should i place them somewhere else on the new or old pipe

 

you wont get codes with the rear cats removed but with the fronts removed you will.

 

So what do u do with the sensors? Just pop them in the straight pipes? Thanks again. I'm hoping to get it done by next weekend

 

I took the sensors out and got a check engine light
