Anyone know where I can get a 3" downpipe for a 2000 Bonneville? I've been told that I might have to have one custom made.

I do not want to buy a kit with headers and downpipe. I just want the downpipe.

I have'nt heard of any bonne specific down pipes and I'm not sure if a Gp one will fit either?
But this guy builds some nice 3" flex pipes and I think you could get one to work

Great, thanks! Hoosier Performance Specialists, a local speed shop, recommended this guy to me. They only knew him as Texan32 on the GP forums though.

I will get in touch with Jimmy, when he gets back, and see what we can do.
