Re: Just got me a used '06 PSD - advice
I do 4" to 5" to 6" and I think its all personal preference. I love the sound of my 6" stacks. They're deep and makes my 6.0 just sound right..too me. Other people hate it and some love it. If you want it louder and deeper I would go with a 5", if you're ok with the way it sounds now stick with a 4". Is it straight piped already? If not that will change the sound of it also. Just remember, its not what everyone else has done, its what you want. You're the one driving the truck everyday after all. Good luck. Once you get that extra umph, you may find yourself wanting a little more here and a little more there..
'04 F350. Typical Mods with tuning by Tadd and Eric and Matt.
'06 VW Jetta TDI. Stock. 42mpg
Sticks and stones can break my bones, but Fords with big turbos excite me...
People think I like girls because guys worth my time are as easy to find as crew cab powerstrokes in the 11's.
