I ordered an extruded honed mani from partstaxi.com on Monday and haven't heard back from them yet. If I don't hear from them on Monday and you still have this I'll take it. My stocker is rusted and possibly cracked.
Yeah I noticed when I did mine many years ago the car sounded deeper and more cammed but I dismissed it as me hearing things. I don't see how a little porting could change the sound but it does.

It def has more power because it'll break the tires loose in second now if I floor it. Never did that before, lol. Even with the factory cat I saw about 1-2 psi drop in pressure at wot. So this thing definitely flows.

Def. It's nice though because it seals up like stock. The ZZP sounded nice and deep but it always leaked even with new gaskets and rusted after only one winter.

I've done at least a dozen of these, probably more, and i've gotten it down to where I can really get them flowing over stock. I'm gonna run one on my car because unless you spend big bucks on a long tube setup with bigger primaries, you aren't going to outflow one of my manifolds with a shorty header. For the cost of a basic downpipe and a ported manifold you can get damn close to the capability of a $500+ long tube setup and 99% of the cars don't need that extra flow anyway, or all the added headaches.
