Re: Exhaust Help
your best bet is to just take it to midas or a muffler shop and have them weld everything up for you! make sure you have a flex pipe or else your header or something will crack.

not true. my friends was not smartly but welded to his header alll the way back one solid piece never broke in 3 years he had it.
you can buy different inlet and outlet size cats...can't remember where though. otherwise exhaust shop weld it up and enjoy it.

Re: Exhaust Help
Anyways...ignoring that post, the easiest way to do it is to have the muffler shopexpand the 2" aluminized pipe to a little bigger than 2.5"; this way it fits over the 2.5" cat. The 2" pipe I believe wont expand (or is very hard) to 2.5" so they will have to enlarge it in two sections. I could only fit a 2" hole on the CNC piece for the downpie flange of my turbo, so I had to enlarge to 2.5 and it cracked, for mine I just welded it because I didnt have the room.
Have a "smokin'" day CapN' Kronik!
