ahh ok, damn I was hoping it was like the gibson. The muffler is where the resinator is on yours with just two pipes going out the back...no muffler under teh bumper to bang on rocks & trees.

 

I don't understand going with a cat back system when everything goes back in the same place as stock. Back when stock pipes had crimps in 'em there was a reason to switch 'em out. Why not just swap the muffler and save a few hundred in cash?

 

my guess would be the stainless piping? If I were going to keep the muffler in stock location I would just replace the muffler but I'm looking to move the muffler near teh driveshaft lke gibson does...I just don't like gibson that much.

 

I can't speak for all of the brands of CAT backs, but Magnaflow and Borla have perfect mandrel bends. Magnaflow has a machine that costs a fortune and can bend some big dia. pipe smooth as a can be. Quite impressive if you have ever seen one. I checked out the machine at Wolf (they do aviation stuff).

The stock H3 system does not, the bends are improved standard crimp. In reality, with an I5 is this the be all end all, ....probably not. With the Alpha a bit smoother flow would make more of a difference IMO.

 

Now they just have to deal with the 4 cats!? The Magnaflow video clip sounds VERY disappointing...not far from stock sound!

 

I have the same magnaflow too and love it, you can usually get a used one on ebay or cragislist. I wanted a valid warranty so I got it here. Magnaflow 16832. Also some of the forum sponsors usually have a sale going on. Either way its a great exhaust system, sounds great, and very easy to install.
