After a quote of $2,400.00 from Ford to fix the bad cats on my stock H pipe, I just had my local shop install a Bassani X w/cats. Driving home was the best experience I've had in my car yet. Finally, I'm happy with the way my car sounds and the volume is greatly increased, even with the cats. I've got 2 chamber flows welded into my stock catback and though I've heard lots of negative reactions, I love it! Popping the gas brings out a thunderous roar and it sounds great all the way through the rpm range. As you may have read on one of my previous posts, I took my car to Ford for a diagnostic test only. The car had a horrible rattling sound and my engine felt very weak. Turns out my cats were bad. With the nex X pipe, my car revs a good bit easier than before and finally the power is restored. In fact, I think my old H pipe must have been going bad for quite some time, cause it hasn't felt like this in a long time. Now I have to get my wife to drive it in front of the house so I can hear it on the outside.
