Hi I have a slight problem.

 I've just gone and had a replica v6 wide arch body kit installed on my clio mk2 phase2 1.2 (lame inno) and then remembered there are to holes in the body kit for two tailpipes like on the V6's. However atm I have a crappy single exhaust that doesn't even breach the back bumper and looks and sounds like shit! Im new to the modding scene and could really use someone's advice on what to do now. How do I replace the current exhaust system for a twin tailpipe system on my clio so that it fits the holes provided on the body kit? If you don't understand what im trying to get it to look like then heres a pic:
