Well last weekend the starter in my V went... yes after only me having  the car 2 weeks... The dealer i bought the car from said to send them  the bill... we'll see how that goes. but anyways, its all fixed now.   When i tried unbolting the battery cable from the dead starter, the  whole post snapped off the solenoid and you could see all rust and  corrosion inside.  But I found out something interesting, apparently the  last shop that did a starter on this car, used the wrong starter.  They  put one in from either a corvette, f body or LS-based type truck, not  the correct one for the V.  Problem was that the dead starter was about  an inch longer than the correct one and it the tight spaces that 1 inch  caused a ton of issues.  I had to first remove the cat converter to see  if that would make more room... nope. And when i did that, of course 1  bolt on each cat flange snapped... joy.  After trying every which way to  get the starter out, i realized it wasn't happening.  I ended up taking  the starter apart by removing the 2 long screws that hold the starter  motor to the nose section.  By doing that i could pull them apart and  basically take it out in 2 pieces.  Once it was out, i realized the last  shop also cut off the factory connector for the solenoid, so i had to  make something up to work instead, you can see the red wire in the  pics.  I used a blade terminal connector stuck into where the connector  should go, them used RTV silicone around it to seal it up.  then I cut  the terminal off the wire which the last shop put on and connected that  to the red wire i installed.  The new starter fit perfectly with no  clearance issues at all.  Even if the Cat was in place, i could swap  that starter in 15 min easily.
Since the catback exhaust was unbolted now already.. i decided to  install the Magnaflow catback system i had bought.  That just involved  drilling out the 2 broken studs on the cat flanges and using regular  bolts in their place. That worked out fine.  I love the sound of it now,  not loud really(still needs to break in) but a great tone and  definitely gave me some more power.
Here are some random pics of this whole insane process....
