Also cutting a hole that is not suppose to be there changes the safety of the vehicle if you were involved in a crash. Thats just my .02 cents.

This is good info.

dribone...interesting....run under the frame and out the side...doesnt look like I could run longtubes though.

i'm still not condoning the hole in the frame, although i have cut more than my fair share of the frame...

but the information provided needs to be correct.

You could then pass the exhaust through the sleeve.......

I thought about that too. That is probably the best way to go, and it would actually be stronger after it is welded.
