i have a 2000 f150 with the 4.6 triton, and i was wondering what would be louded and overall sound better- flowmaster 40 series, or like glasspacks, im doing side exhaust, something like the lightning. just curious, thanks guys(and girls)

 

I vote neither. I suggest using a stainless-steel, straight-through design muffler. Each of those mufflers has one of these traits.

 

just go ahead and get straight pipes because the glasspacks will plowout anyway.. and the 40 will sound good but straight pipes will be louder and cost less.. just my 2cents

 

in my opinion the straight pipes will be louder but the 40s will have a better sound to them just my 2cents

 

glasspacks are louder 40's sound better and straight pipes are loudest,but if you want it to be loud but still keep a little backpressure on it then go with glasspacks,more performance go with flows

 

I have a glasspack and to tell ya the truth it's not very loud. Cut off the last two cat's and throw on straits, then you're cookin!

 

I vote for the 40 series flowmasters. I had a true dual setup of 40 series flows along with headers on my old 97 4.6L.I loved the sound and everyone who heard it loved the sound. I went a different way this time with the L. I put on a set of magnaflows. Its a different tone but not that bad. They are fairly quiet at idle , you can definetly tell u have them under acceleration, and not bad loud cruisin down the road.

 

well,nothin is loud on these at idle or at very low rpm.i have straight pipes and mine isn't that loud until i get on it.i liked my flow you could barely hear it cruisin,but when i got on it,it sounded great.especially when i gutted the cats.it sounded real good then,but i wanted it louder.
