i want to have as much in my head as possible when i go to get bids for my magnaflow exhaust. from all the threads i've read, on my 04 screw fx4 i want true dual exhaust with an x pipe and both tips out the back. so di/do or si ?
anyone know if the di/do works with the 04's? i see a lot of guys have theirs dumped but i kinda like the look of the tips out the back. does anyone think i'll have a problem if i go in and ask for this or maybe is there something im not thinking of or should do different? is there anything special i should ask for maybe?

 

you could get the magnaflow with the internal x pipe.

 

true dualing with two si/so mufflers is most common and best sounding IMO.
