I would cut mine off but I got emissions to pass.

Last Q before I order this ****. Super 40 DI/DO or 2 SI/SO? Are the inlets the same distance apart on the DI/DO as the distance b/w the stock piping? I know that sounded quite retarted.

 

[dcZ71]

i know magnaflows are 5.75" center to center on the inlets/outlets

somebody get a stock measurement.

 

[1990GMCSIERRA]

hell they just cause problems ,,
