Thanks for the advice, Was VERY helpful, I have one more question, alot of the downpipes i have been looking at say that they are for offroad use only because of emissions, however they have all been american sites. I was just wondering if any of you knew if that was USA law only or are these downpipes illegal in both canada and the states, and is it uncommon for people to put illegal downpipes in their cars? In my mind it can't be that huge of a difference that a cop would see/hear me and pull me over because my car sounds too loud due to my dp. But thats just my logic. Thanks for any replies i get.
When they say "off road only", that generally because the downpipe/up-pipe have no catalytic converters on them and therefore don't pass emissions...in the US or Canada. There are a few companies who make smog legal pipes...as I said, COBB, Perrin etc..
