I have a 96 F-150 and i want to start fresh with exhaust from manifolds or before the cats back. i want LOUD!! but legal. i don't have to worry about cats so they are GONE! I was thinking about Flowmaster 80's but i don't know how loud they are. i heard they were one of the loudest Flowmasters but i dont have a brand preference just Loud!!!



Help!

 

if u want LOUD u could always straight pipe it. not sure how legal it is tho. myself, i think flowmaster 40's would sound good, and loud of course. im puttin a fm 40 si/do on my f150 in the near future. imo, id go 40's.

 

I'm running true duals with 12" Aftermarket High flow cats and long tube headers.... It's just about as loud as when i had 27" cherry bombs bolted to the headers, mayber even louder. Best of all, it's quasi-legal

 

If you want loud, take everying off, the manifolds too, that'll be LOUD....

 

i'm sure he wants to keep his valves and wiring also. i had a 302 with true duals and 8 inch glasspacks and bells angled out the back. that was loud. 4o series is the deepest most aggressive muffler made by flowmaster.

 

... oh, btw the 80 series is a GM F-body crossflow muffler... I had one on my firebird

 

A set of Flowmaster one chamber race mufflers would be loud too. Never heard a set though.

 

What is a crossflow muffler and how does it work??

I've never heard of such a thing (i'm not questioning your knowledge though)

 

look up under the *** end of a firebird... the muffler is set sideways and flows in a patern that i can't describe here...

 

Go with true duals and glasspacks..... they are a muffler so itll be legal..... the shorter the glasspacks the louder it is, and then put echo champers (big mouth tips) out the back ..... itll be loud loud.

 

yeah like i had on my 82 302. true duals with 8 inches on it no cats and big bells. my truck had a problem so it even shot 3 foot flames out of each pipe out the back when you revved it 3 times in a row. that was real loud and cool cuz nobody would park behind me at school. LOL

 

lol@f100 ...... that would be cool, LOL

 

How did you cut your cats off when you have o2 sensors?

 

you put a bypass on the oxygen sensors it called a mifeliminator or something

 

flowmaster makes 1 chamber mufflers that are pretty loud call up jegs or summit for prices and avaliblity
