I'm getting true duals put on my 4.6l single cab next weekend. I just want to be assured im going to get the loud deep sound im looking for. Im changing my exhaust from a 12"si/so dynomax bullet with a 4" tip, to true dual 12" dynomax bullets & 3.5" slant tips with 2.5" pipe, without messing with the cats. Does that sound like a good(loud) setup?

 

How did your SISO bullet system w/ 4" tip sound? I only ask because I'm getting that exact same system put on my truck next week. Currently my truck has the stock system. Just curious.

 

The duals will be just about be louder in every acceleating scenario but the idle will be louder with the single exhaust due to the stronger pulsation.

 

Ya it will sound different, but i don't know if it will be a loud as your thinking though.

 

my single bullet sounds mean! its a great setup but I can never stay happy & I want to try something new

 

^ then do it

 

06 5.4 3 inch si/so with 4 inch tip.

go for it. check out my setup in my album. deleted rear cats, dual 2.5" pipe to di/do 40 series 2.5" out to 3.5" tips. Sounds awesome. Gonna run LT headers soon.

I got the true dual setup done! I ended up going with 2.5" pipe and 3.5" tips

1 muffler trying to quiet 8 cylinders will be louder than 1 muffler trying to quiet 4(true duals) or 2 mufflers trying to quiet 8( duals with x or h pipe)

 

Sounds nice, snappier than how my 5.4L with the same practical setup sounded.

Your post doesn't show any enthusiasm or excitement however, not 100% satisfied? Do you feel it sounds better at all?

 

yeah, I didn't show much enthusiasm at all but the new setup sounds amazing! its definitely louder then my si/so setup, & its not even broken in yet...
