Others who have tried this may disagree
There seems to be some debate about this. I heard it was only an EPA thing on the USA. Honestly I wouldn't mind loosing them forever, but I got to go back with what I have or spend money I dont have. The pipes are decent and need only cross-overs. I have seen several posts about this solution and it seems very viable and much cheaper.
