Nah it's just for looks. Be sure to specify the burnt titanium blue tips if you don't want the plain ones. This is a lot of money to drop on an exhaust or any mod really, so be sure it's exactly what you want before you buy it
I think that's about as cheap as it gets. I got mine from customcarscentral.com along with the art pipes and swaybars. They're an official reseller of MD. Maybe you can get them and b2autodesigns.com to get in a price war with you, but I didn't try.
Hey bro, I wanted to do a shoot with two Zs and your G. I got both Zs potentially. Also, I have two models I'd like to use in "classy clubwear" for a night shoot in either downtown Huntsville or Research park area. Somewhere between Labor day and Halloween is when I want to do the shoot. Would you want to calobrate and do it?
