Exhaust banging floor board???

[JeremyRay]

Need a little help with a 2000 WS6 after installing my exhaust. I installed a set of Kooks long tube headers, a Kooks y-pipe with Magnaflow hi-flow cats and a Magnaflow cat back. Now when you take off in 1st gear and sometimes shifting into 2cnd, the exhaust bangs against floor pan. If this has been covered in another thread please point me in that direction. Thanks.

Hello!

Exact same setup here on our car. I had a clearance issue with the Y-pipe on the driver side and was able to resolve it with careful adjustment. The fix was to rotate the slip joint on the Y-pipe to obtain maximum clearance where it passes beneath the underbody brace. It's possible that your engine mounts are whooped (especially if they are the stockers) and this causes the engine to drop in the front and forces the exhaust closer to the underside of the car. A set of poly mounts would remedy this issue. Absent either of those fixes, they do make a special bracket to hold the exhaust in place -- I'll go find it and post a link.
