clunking noise with new exhaust

So I put on a BBK xpipe and the MBRP Race after cat exhaust today. Everything is tightened up tight as a button. When driving and letting off the gas or shifting as well as over bumps I'm getting a clanking noise. Any ideas what it is or where I went wrong? Everything looked good when we had it on the lift but it's to hard to crawl under when it's on the ground. My drivers side is super close to the panhard bar brace so I am suspecting this but it sounds like it's further up front when driving but that could just be my ears playing tricks. Any ideas?

with it on the ground you should be able to hit the muffler side-to-side and up/down (one side at a time) to see if you can duplicate the noise.

Just tried and I'm not really getting any noises. It doesn't really move much at all in the back when I try and shake it.

My guess is that your OTA pipes are hitting the panhard bar support brace.

Okay. I'll check it out. I know it's close. I'm thinking I am gonna need some welding o the X to the cats as well. That BBK is a pain to seal. Sounds like turd on cold start up with little leak. Thanks guys.

I ordered a tubular panhard bar support brace from Mustang Guys for my car when I installed the full 3" exhaust. This gave me plenty of clearance and no chance of the exhaust touching the support bar.

I've got a Whiteline Panhard Brace so I am thinking it is def hitting there a bit. I figured out the clunking. The drivers side clamp was rotated to close to the undercarriage and was smacking it. So hopefully that's solved and I can tackle the leak.

Double check and make sure all connections are tight. When i put my axle backs on. I had a clunking noise too. When i took off my factory exhaust i unbolted the exhaust mounts. When i put the new exhaust i i finger tightened them along with everything else then when i was tightening everything i forgot the driver side. I tightened them and the clunk went away. Double check all your bolts.

So the clunking noise was from me putting the clamp on the drivers side pipe to close to the body and the bolt was hitting the body. Stupid but easily fixed. All is good under my car now
