cut out or downpipe first?
 

hi i plan on doing both mods here real soon. gonna get either a hogan dp or one from zzp and a cutout from dmh. my question is if i cant afford to install both at the same time. what should i get installed first or does it not matter. also a07 monte as far as cutout is 2.5 or 3"? thanks as always guys!:thumbsup:

I may be biased.... I would get the dp first haha

Get the dp first, most install cutouts on the dp so thats what i would do

Dp first so the cutout is only welded in once.

gonna put the cutout basically under passeger side at rear tire. still think i should or need to install dp first. also on the cutout it 2.5 right?

If its stock exhaust its not 2.5" I'm not sure the size. Honestly a cutout way back there is useless.

I would get the cutout on the DP :)

Yeah its pretty usless to put a cutout that far back

i havent seen any of the ls4 guys run the cutout on the dp. they usually put it before the y pipe. the cutout should be 2.5" i believe the factory exhaust is 2.5 and then reduces at the y to 2.25 or even 2". i believe that catless downpipe gives the ls4 cars a far better boost in performance over the cutout.

ty and yes every ls4 i saw with a cutout was at the rear tire before the y. thanks for all the input. i want the cutout more for sound than hp but i think i may just get both.
