I have a 1997 blazer 4 door 4x4 and was wondering what the measurements would be for the inlet/outlet on a new flowmaster or cherry bomb glasspackmufflerfor it. thanks.

 

Some people say they have 2.5" pipes, but mine are 2.25". Measure your's to be sure.

 

2.25" offset in/center out is standard. A lot of people, myself included,went to all 2.5" piping when redoing the exhaust system.

 

thanks guys. i appreciate the advise. ill post pics when i get the exhaust done.
