Well, after a few problems with hanging the exhaust out of the way, I can now post and say man, the Magnaflow catback is SWEET. I got it brand new for $280 shipped from Performance Curve, a company advertising their products on ebay. I received it in two days and installed it yesterday. What a difference! The exhaust I had before was not stock, but everyone tells me it was probably worse than stock. It was a pathetic setup - muffler was too quiet, I'd get walked in the top end by other LT1's with the same mods as I had.. I'm definitely feeling (and hearing) a great reward for my money. Nice and quiet at idle or cruising, but man does she purr when you get on it. Nice and throaty - sounds like my friend's 2OTL almost. Anyway, just wanted to pop off my two cents and tell you the Magnaflow exhaust is AWESOME, and you can't beat a polished stainless steel catback for $280 shipped. That's cheaper than the hooker even. Plus, 3.5" polished stainless tips sure do look nice on the back of my Z.

EDIT: BTW, for some reason I'm now chirping tires in second and third gear. Dyno proved magnaflow gains at 14rwhp/18rwtq over stock, so I think i probably gained a bit more than that if this other setup flowed worse than stock.

Well i'm glad your happy with it but i think the sotp feel is in your head. I didn't feel anything with my borla and i think borla has to be one of the most free flowing considering if you want half of it will by pass the muffler. My friend didn't feel a gain either with his catback. If it makes you happy though then thats what matters.

 

Maybe it just feels faster because it sounds louder, but what accounts for the tire chirping?

 

Don't worry, you did gain HP and TQ by going with the Magnaflow catback.

Have fun and enjoy.
