Very nice looking, great job on both the motor and the exterior. The only thing that doesn't agree with me is the center exit exhaust. Don't take me wrong, I like the idea of a center exit exhaust, but I would change the tip. Eiher get the Borla style tip that they make for the center exit, or if it was me, I would do a "custom" double tip kind of like a Mini Cooper S's exhaust. The single round tip that you have now just looks off.
I agree that it looks off. I had a larger single resonator/tip that sounded like poo and it got tossed then I went with a dual setup that didn't really sound right either. The current one makes the exhaust sound just like I want it too, but I'm not crazy about the way it looks.
Anyway, That tip's days are numbered (specifically it's hours are numbered). I just made the first cut for the side exhaust on the driver's side. I would finish it tonight, but I can't get the tip I want (no 24hr exhaust shop), and besides, my wife just got home and laid down the law and told me I had to quit for the night. I'll post pics tomorrow when I get it finished.
