What should I do now? (wanting louder)

Halverso_99 · #1 10-14-2009, 08:10 PM

My Truck is a 99' with a 4.6. My current setup is BBK Shorty Headers and a single Cherry Bomb glasspack with stock piping. I also have a Airaid CAI. I am wanting to go with something louder probably duals and have been thinking about dual straight pipe with hi-flow cats ran straight out the back but i do quite a bit of towing so not sure about that. Any suggestions on what kind of a setup I should do?

straight piped?

no on straight pipe. go duals with high flows and run either dynomax bullets or SLP LM1s. 45 out the rear. replace all 4 cats with 2 magnaflow 94106 high flows. thats pretty much as loud as you can get, without asking for a noise violation.

what would be louder between the loudmouths and the bullets?

personally i like the sound of the f150s straight piped

if i had to go with a muffler either bullet or flowmaster 10 series

check out this guys vids, he has one of it straight piped and with 10 series

same volume, different tone. bullets are deep and aggressive, SLPs are raspy and hollow(ish) sounding

how raspy are the slp's? I think i might go with them but cannot find them for sale anywhere.

i cant find a 2.25" LM1, which would be better than 2.5"

I am torn. Can't decide now.

Halverso_99 · #12 10-14-2009, 11:37 PM

Bullets will sound good. Straights actually sound really good too

pipe as in no cats? will perform in high end much better, not so much low end, will sound good. hi-flows will sound pretty good, more aggressive and a little less V6 ricey sounding, and legal.
