Integrated Exhaust Manifolds

Cadillac CTS 3.6L Engine

Under the cover of darkness (okay, not really), there has been an evolutionary change going on beneath some new car hoods. Something that we all have grown to love & hate may finally become a thing of the past. For these new GM V6 engines, upgrading to a set of long tube headers for some added fun at the track is a total impossibility, because the exhaust manifold doesn’t even exist anymore. A tragedy? Nope, not really.

You see, General Motors has been starting to integrate the exhaust manifolds into the cylinder heads themselves.  This is absolutely terrific news for several reasons. It gives engineers & technicians a bit more room to play, weighs several pounds less, has fewer gaskets to blow, and it locates the catalytic converters closer to the cylinder heads which reduces emissions even further. Oh yeah, they also claim that these fancy new heads flow better than the old exhaust manifolds used to. So unless these integrated cylinder heads start cracking from heat cycles (plausible?), they are really nothing but great news for the enthusiasts and environmentalists alike. It’s a strange new world out there, and times they are a’ changin’.

2009 Cadillac CTS…..wait for it…. Convertible!

Just when you thought you had seen the roof cut off of everything (I’m looking at you Subaru STI ), somebody goes and lops one off of a 2009 Cadillac CTS, and throws it on eBay.  This whole “turn my car into a convertible” thing just puzzles me.  I have to assume that if the owner of this Cadillac wanted a convertible sooooo badly, they could have just bought a new Cadillac XLR at the time.  I mean what’s the price difference between buying a new CTS and having it turned into a convertible vs. buying a new XLR.  A few grand?  Ah well, at least it isn’t a full time convertible, that would be depressing.  Instead, in true Cadillac form, it has a luxurious power top, which you can see in action in This Video.

While it is actually better looking than many convertible conversions, it’s just not my forte’.  To each their own I suppose.  Nobody likes my truck either, but I still dump money into it like it’s a 401K, of which it is clearly not.  But I digress…. Here is the beautiful drop tizzop CTS showing off all that its got. What do you think? Is it your dream car or another nightmare?

CTS-V Coupe: In Real Life

A Real CTS-V Coupe

Having good friends at a variety of car dealers is really cool, especially today.  This morning, a new CTS-V Coupe was stopping by a local dealer, and a good friend of mine snapped a pic for me because he knows that I would sell his soul for it.  Without further adieu, here it is.  Just sit back and appreciate it’s beauty, because nothing else needs to be said.
