big speed bumps are satans weapons against mustangs

looks like that muffler is too close-i hate to sound like a dick but thats a problem. your exhaust moves when you get on 'it and when you hit bumps. its held on by rubber hangers which allow it to move. if you cant do fix this yourself get it to an exhaust shop and tell them to check your muffler/driveshaft clearanc issue-they can take it from there.

im guessing you moved your exhaust alignment on impact. its just metal it can and will bend-luckily it can be bent back

Drive Shaft for the win! I deserve another cookie.

fwiw, when you brake the rear of your car rises up and can cause things to happen the don't normally happen...which is why it hits when u jack the rear......just tired and rambling.

good to hear you found it

CATASWAMPING!


looks like you found a way.

Please please please be absolutely sure about jack stand placement. Get under an improperly supported car and you are signing a DEATH WISH. Seriously. Also, buy some proper wheel chocks - stop using 2x4's. And always work on a LEVEL surface.

I believe the proper jack stand location is not where you have it, but at the same point you put the jack to raise the car. And that IS noted in your owner's manual.

On your problem, I agree with the other posters who say there is no way your muffler should be that close to your DS (jacked up or on the ground). The mark on your DS is key evidence of contact. It's hard to tell from pictures, but your mid pipe may be bent out of whack. If so, I don't know whether it will be more work to fix it, or just get a new one.

But if I were you, I'd start by loosening all the bolts at the header to mid-pipe, and mid-pipe to cat-back. Then try to wrestle the exhaust back into proper position. Start from the front of the car and work back. Get that mid-pipe back on both hangers. And get the passenger muffler away from the DS - about the same distance and the driver side is in your picture.

Oh, the other way to tackle this is to find a good muffler shop and have them do it. After about $50 at a reputable shop, and you should be good to go.

Good luck.

A safe place to place your jack stands is on the front LCAs. Place the center of the jacks between the 2 openings, just under the spring perch. Once on the jacks push on both front fenders to make sure there is no movement. Where you have them now is a recipe for disaster because you will be pushing and tugging.

Also, I've done some research in the past and other peeps had scraping on the DS but it came from the emergency brake bracket just above the DS. Just something to think about. As mention before, loosen the exhaust and move the muffler over some. There should be no exhaust leaks because the male and female ends are like ball sockets and should seal, even at not so perfect angles.

To keep my exhaust from hitting the frame, such as in the rear, I've used electrial wire - solid not stranded wire. Pull, or have a helper pull/push the exhaust for clearance while you wrap the exhaust.

Next time go over that mountain slowwwwwly.

btw i saw a picture online of a guy who drove his car onto four ramps that it looked like he made himself out of wood... anyone recomend this?

I don't. I'm sure if you made them strong enough you'd be OK. But how would you ever really know they are strong enough?

Better yet, pick up 2 sets of those plastic ramps that you can get at the parts store. Then you could jack it up and support the car on jack stands AND ramps. That should be the safest way to go. That's how I do it if I have any significant projects. And when I need the car higher up than the ramps will take it, I put a row of cement pavers under the ramps (or two rows piled ontop of eachother).

I like doing stuff myself too. Did my own gears, HCI, etc. But exhaust is one of those things that is just SOOOO much more efficient to do in a shop with a proper lift, that you might just want to think about it.

Here is a picture. When I was under there I realized it may not get up high enough for you since you are doing the exhaust. It should work but if not it's good for future jackings.

I jack and put my jack stands on the flat spot at the ends of the unibody

and beings nobody told you the little shock in this pic that runs diagonal is the quad shock


Also like mentioned before go over speed bumps at an angle and SLOW
