I have a 1998 f150 4.6L V8. When I bought the truck it had dual exhaust on it already. A week ago, I put on a flowmaster 40 series on my truck to make it louder, and it's not that much louder. What else can I do, or should I just dump the exhaust?

 

if you want loud go with 12" glass packs i put one were my factory muffler was and run two 18 echo chambers out in front of the rear wheel like on a lightning and I think its the loudest truck in town course theres only 5000 people in town too.

 

i dont know a lot about glass packs. do you keep the muffler on and add the glass packs to it? is it alot louder? I just got the new muffler and i dont really want to take it off because then i just wasted a $100

 

huh I would take the 40series off but U spent the money so next time U get it redone and if you still want it loud go with glass packs my buddy just put a 40series on his and compared to mine his sounds stock, dont know what they would do or sound like behind the flowmaster id think it wouldnt do any thing in front of it but behind it I just dont know, and hey if you get them look at them before you get them welded on and make sure you can see all the way threw them other wise they will just sound like a muffler.

 

thanks for the help. i will probably get some glass packs and keep the muffler for later on if i want to make it quieter. does anybody know about dumping the exhaust? that is my other option. i heard that its not that much louder, just resonates more in the cab. is this true?

 

or anybody else know anything i can do that i dont know about?

 

if youve got a 4.6 with duals and 40 series.. it should be very plenty loud, unless you still have cats, take the cats off or go with high flows, glasspacks are stupid and sound like a dump truck.

 

I would go with some offroad pipes or go with Magnaflows.
Glass packs sound to deep and dont have that true truck sound.

 

i dont have true duals. just a single pipe going into the muffler with two coming out.

 

Dumping it could make it a little louder. Upgrade to ceramic headers and high flow cats too and it will be.

 

what are some good cats and headers and about how much would they cost

 

header and high flow cats

 

i looked at alot of headers and they were about 500 to 1000 dollars. i dont have that much money. are there cheaper but good ones out there?

 

I have to disagree it all depends on how you dump it after you come out of them Im very happy with the sound of mine ofcourse it could be a SEMO thing o and It depends on how long of a glass pack you buy mines a 12" I think they make them in 12-18-24" not to sure but most bob/dump trucks have 24's and they dont sound as good as a short one with echo chambers....

 

agian I disagree it has a un explanible sound not to deep kinda can i say hi sounding for a truck well very unique dont know I like it.
very very loud like hear it four blocks away loud!!
