Get rid of your stock mid pipe! Don't try to ghetto rig your stock one. You can get a nice H pipe for under 200 bux. Also if instil the mid pipe your self I have a few tips for you on them hated manifold bolts. If you do not DD the car get you some 3 in 1 oil (i think it works allot better than WD40 for this type of stuff) and soak the piss out of them. I mean really do it in, wait about an hour or so and do it again. If you can let it sit over night like that. If you still have a hard time with it try to heat up the bolts a bit with a torch. You can get a cheapo at the hardware store for about $25. Heat the bolt your working on up until its red hot and put a breaker bar on it and get a a hard turn. That should get it.
