Here's a before and after sound clip of the non-resonated Boosted 6 lower downpipes, if it helps.

Late to the party, I know, but do you have LDPs? I have seen strange behavior from the smallest air leak upstream of the O2 sensors and you might not hear the leak or see a CEL. If you've done down pipes, get under there and retighten everything.
My first car was my sister's red Mustang convertible. My car before the Z was a Volvo C70. If I didn't get the Z I would have looked for a CPO CLE 53 cabriolet. You can even run it in the winter... with the top down.
Some time ago I wrote about owning two-stroke SAABs in my youth and that was the first car I owned with a high beam stalk on the column. SAAB drivers would always flash each other. Like that final scene from Freaks... "One of us, one of us!"
I haven't had the opportunity to acknowledge another...
Got the lower down pipes in. Took four hours if I don't count a drive to Harbor Freight for a 1/2" impact joint.
The Quick Jack's made it pretty painless but having a flexible lighted pickup tool to guide the sockets really helped.
I included two sound files. First one is before. Second is...
Hey, I luv my yellow Z! I think it saved my ass a couple times because it's so hard to miss and I'm guilty of DWO* in a hellishly fast car with blind spots.

Thanks... I just looked at what it costs to get front and rear adjustable camber kits from Z1 and it made me question the wisdom of lowering my car. I guess I could find a lesser costing source or just monitor for uneven tire wear for the summer. But I do need a project...
Got my post lowering alignment. I could feel the difference on the ride home. The Z seemed to be more sensitive to steering input.. Could just be in my mind, too. As long as I don't ruin my tires it will be fine.
On to the next project.
