I don't believe it will fit a Bonneville. The interlock flex section is at a different location. I would only recommend a catless down pipe for race applications. You won't be able to pass emissions unless you change some codes. You will need an O2 sim or PCM programming to remove the 137-141 & 420 codes. They are not legal for use on public roads. I've been hearing that new emission laws will soon go into effect where if you have any check engine light (emission related or not) you won't pass emissions. $60 isn't bad, but a new zzp downpipe with cat is around $160. If you go with the craigslist offroad down pipe you will have to get your PCM reprogrammed ($100+ if you can't do it yourself) or a o2 simulator for around $80 if you can still find one.
