Hi Scott,
Recently I've changed my exaust manifold and catalytic converted for my 2007 prius. 173,000 miles.
Toyota dealer quoted me a high price to fix this issue. :
NOTE - ENGINE VIBRATION DUE TO AMARKET EXHAUST BEING TOO LONG, MOTOR IS BEING PUSHED FORWARD .
Is there any video or guide to address this and fix it on my own.
Thanks

Are you having network issues? If so, then please wait until you have a stable connection. If you are pressing the submit button more than once, please stop. Press it once, and wait for it to finish processing. Otherwise it creates more work for moderators to clean up, and eventually the system will automatically ban you from entering.

unless you have metal cutting grinding and welding tools and know how to use them, it's best left to a pro.
