I have a 99 stb, and replaced mine recently. I don't know what your emission requirements are in Canada, but in the UK, a decat downpipe (which would give the greatest performance and noise) wouldn't pass the emission requirements. So the middle ground option is a downpipe with sportscat, which gives improved air flow but still passes UK requirements. This is the one i have and apart from the fixing bracket which had to be cut away it was a straight fit. Noise is greater and there is a noticeable but relatively small performance gain. Best of luck in your search.
