Ok Guys,
As I ever so slowly fab up my 4" SS exhaust, I have run into the question of how you guys have made your vertical penetration into the box. The way I see it, you have to cut a frame crossmember and a cross girt on the box itself. I know that I can run the exhaust up without cutting into them, but it would cause me to lose some additional box area
Any ideas or help would be appreciated. I searched through the picture archives- but could'nt find any underside photos.
Thanks--Jeff
