Who Would of thought.

Greetings all. It's been awhile. I hope everyone is doing well.

The past 7 months have been very interesting! So it turns out that the sole and root problems of 90% of my T-birds performance problems was the exhaust! Once while driving home I heard an ungodly whistling noise coming from the exhaust. Perplexed by this I got under the car, unhooked the exhaust right under the drive shaft and tranny only to find countless pieces of catalytic converter lodged in various spots throughout the piping from the Cat-Y piece back! (I still have one apple-size piece sitting on my tv right now!) I took the car to my local exhaust guy and had an entire new system from the manifolds back put on. I had high-flow catalytic converters installed with new 2 1/2 inch pipe from the cats back with two lovely sounding flowmaster installed. Aside from the engine having 130,000 miles on it, it was like I got back the other 150 hosepower that seemed like the other 50 I had was missing! I put an aftermarket intake manifold on it too after I cracked the original one, along with a GT cold air intake kit that I customized to fit my Thunderbird. Finally, after almost 2 years of fighting with it I can safely say that with the new exhaust and mods to the intake system I think I'm pushing 215-220 at the wheels and close to 290-300Ft-Ibs and I can actually feel it!

Just thought I'd share.
Has anyone else ever come across this problem with their catalytic converters?
cheers,
