The reason this joint is so dead is because most people don't put real toy's on they're MO. While it's possible, I don't think I've ever heard of anyone putting turbo's, CIA's, upgrading the exhaust, etc etc. Truthfully, I just don't have the money to put jack all on my truck. I would like to point out though, that if you are hip to doing that kind of wrenching on your kit, check out some of the other more fun cars. The new GT-R, maxima, 350/370Z, and infinity's G series cars all rock the Q6 engine. The bay is laid out the same way as well as down piping for the exhaust. As such all they're toy's, turbo's cat backs, stainless headers & Y pipe, CIA, all should fit just peachy. Be careful with the CIA though. While it should fit, I think the bolt points are a little different. Plus unless your one of those sick bastards that plan on lowering a truck, a true Cold Air Induction can be susceptible to water issues with going through puddles. The one that I found on ebay by Injen, that lists for like 304.66 as a buy it now, is actually wrong. That's the one for VQ40/56. But if you look up injen intake, you'll find they have a specific truck one for the Murano. It give you free flow and a 3.5-4" pipe.

On a side note though, if anyone has put a lifter kit and some nice BF all terrain 33's on they're rig with a decent winch, I actually don't want to know. While I do seriously dig my MO, it sooooooo should not be out on the trails. The all wheel lock just isn't up to the challenge.
If Naffdur see's this post he'll probably bring up the fact that a Murano is essentially an altima on steroids, NOT A TRUCK. Call me cooky, but if it looks like a duck and sounds like a duck, it's probably a freakin duck. Granted I don't plan on trying the Baja 500 with it or try towing 12000 LBS worth of crap with it. It still seems very truck to me.
Good luck to y'all and if you start putting toy's on, please let me know. I'd love to see it all in.
