Ipurchaced a 1985 buick regal that I always wanted. I just painted it and wanted to put in an exhaust my problem is I know it's a 6cyn but im not sure what size eng. I know where I could find the things I need I just dont want to order a exhaust system that's not going to fit.

 

i believe it to be a 231, 3.8L. but if you call any auto parts stor with the eighth character of your vin, they can tell you for sure.

 

Thanks alotI appreciate the info.
