ok i know that this topic has been brought up many times.but here goes.
i have a 99 f250sd with a v-10. it has a aftermarket cat back exaust. not sure who makes it. took it to the local muffler shop and he told me it was a camaro muffler. its all wrong. cant explain how someone could screw something like this up. but the funny part is that it sounded nice.anyway on with my question. i want to find something similar. cat back system. 3 inch in and 2.5 inch out. singel to dual. maby woth nice tips. anybody have any input?
thanks

 

my opinion is to get you a good baffle style muffler (seems to sound the best) like a Flowmaster/IMCO style, with a 3" in/2.5 dual outs! that's what i run and i've loved it ever since i put it on! check out the sounds clips on my web page for other variations.

I think Borla makes two different dual bolt on cat backs.
