Re: Help! Bolt in exhaust pass through?
There is a member here, can’t recall his handle, that cut holes in his crossmember and has been running it that way for several years without reinforcement and he has a healthy big block IIRC. I cut 3” holes in mine instead of 4” and don’t plan on reinforcing it.
