The portion of the frame I modified, isn't very structural. It already has a bent/fold in it for the exhaust in the first place. Although I do not advise it. I went to a local body shop. I've got a couple of friends there. For the ammount of the bending/hammering I did, they said it wouldn't be harmfull. We even put the car on the lazer frame rack, to see if it effected anything structural. The lazer frame macheine checks about 150 points on the car's frame/unibody. The hammering didn't effect any of thoes critical points. But like I said, I woulndn't attempt to do this. The only reason I did, was because of the resorces available to me.
