MSP Cat-back fit on MP3s?

[apexcivic]

Hey guys this is Ben from Apex Motorsports. We have made a 2.5" and 3" cat back exhaust for the MSP, from all the e-mail I got from other members the MSP exhaust should bolt on to the MP3s correct? how about the rear lower piece of the body kit? it is the same? thanks for any info MP3 owners can give me.
