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.

the reason why the ls4 guys put the cutout there is because the y pipe reduces down to 2.25 or 2". so you want it before the y. i dont know how much room there really is on the downpipe for a cutout not to mention im going to assume your car would stink having the fumes pumping right under you. this is usually acceptable on a hot rod. not so much on a car from this era. for what the cutout is going to cost you, it would be far easier, and cheaper to remove the mufflers and straight pipe it. if i had to get a cut out i would get the manual one. nothings worse than the motor burning out on it and having to buy another one, or having something get caught on it(this happened to on guy on tech).

Buy the DP, sit it on a shelf for a couple weeks and let it look pretty. During that time think about whether or not you want the cutout or not. By that time you might have the $$ saved to buy it if you decide to and then you can have all your exhaust work done at the same time saving on labor cost at the shop.

Buy mods and let them sit?!?! Unheard of haha. He will look at it and wanna put it on that second if he's like me

I never said it would be easy! :rotfl: I've sort of conditioned myself over the years so it's not such a torture for me now to have parts laying around. ;)

lol to all of you!! im thinkink dp first then go from there. i lost 400 at the casino tonite so im already beating myself up!

Hi, cool mods, I think a member here is selling a cut out... Check the for sale posts, I believe it's brand new as well... Good luck...

Well ordered by downpipe from zzp today. Gonna get the cutout soon.
