Help on exhaust setup fitment

[Simon]

I recently purchased the Manzo v1 catback exhaust. I am planning on changing out the front pipe and overpipe but i am confused on whether it would fit or not.
for instance, the muffler piping that connects to the overpipe is connected by clamps.

I looked up a few overpipes and they all seem to have gaskets on both side of the pipe.

this is the front pipe i am planning on getting: http://www.ebay.com/itm/INVIDIA-60mm...411316&vxp=mtr

can someone tell me how do i go about changing out my overpipe? and my front pipe has gasket on both side but I am skeptic on whether or not it would fit or not.

I am planning on running the manzo v1 exhaust, invidia overpipe, and invidia catless front pipe.
any help would be much appreciated.
