Factory crossmember?
Hello All,
If I drill two 3" holes in the factory cross-member (for exhaust clearance), will I need to worry about the structural integrity? David |

Re: Factory crossmember?
I have seen several folks here do that and they also put steel pipes in it to give extra support, just to be safe.

Re: Factory crossmember?
Can't really answer the question on the structural integrity, but this is how mine are done.

They're just made of some scrap piece of steel pipe.
