2000 Buick Regal sleeper HD

Lots of mods If you need help modding your 3800 feel free to leave a message. People have asked so I will say I have ZZP headers. Love the quality and ease of install vs others. But for those on a budget Speed Daddy headers are nice bang for the buck. Just use band clamps from your local Napa. And some RTV copper spray and sealant. You will have no issues.
