Jeff -- "toning down" your Mustang? You must be gettin' OLD.
Like me. LOL
Actually, when I had my '89 5.0, I ran all stock except Dynomax cat back. The drone at 2000 RPM was annoying, but the start-up and idle sound was worth it.

P.S. -- I'd still like to take you up on your offer. Maybe we could find a place where I could take some more cool car pics for you, too... Remind me what part of town you live in -- I'm near the I-10 and Ray area.
