Update: Forgot to update results. All fixed, no leaks and nice and quiet now! Thanks everyone for suggestion and help.

 

Gremlins keep on getting back into my "excellent" repair capabilities! LoL Couple months ago I noticed my "excellent" shadetree repaired replacement of the left cat Converter has started "wheezing" when accelerating. Gotta be my bad repair using the exhaust clamps I used. Been putting off jacking and crawling back under the car to see what's to be done. Guess I should mark the installed position, with welders chalk, and try my best to weld the seams. Of course that means the whole exhaust system has to be pulled out to make the repair.

Getting a little too old to be crawling around under my two Xfires to make repairs. A simple brake job is something of a task nowadays and I am not willing to spend the "Flat Rate" labor charges that garages want these days. All the aches and pains have started catching up with me. Starting to think I should be selling one of them.

 

UPDATE: Finally got tired of hearing the exhaust loudly "wheezing" and the really embarrassing look when going down the road. Three days ago I jacked it up to see where the problem lies. When I cut the old Cat out I noticed the exhaust pipe connection was not round but oval shaped. The exhaust pipe clamps, at the union, were only tightened with the ratchet and had not really formed around the oval shape of the exhaust pipe. I repositioned the clamps and used a breaker bar with an extension pipe and really cranked down on the nuts. It has been quiet and no exhaust leaks.
