Been doing some checking and by all accounts, it seems the V6 Cav shares it's exhaust with certain other models..
Would anybody be able to verify..
1) That the standard V6 system comproses of centre section and tail section (or is it just one part from the cat back)
2) The centre section is the same as an Ecotec 16V Cav
3) The tail section is the same as a GSi Cav
