[W126 Coupe] Exhaust Opinions

[stefansj at canisius.edu]

Hey guys, So the transmission is in and working very well but now I have 
another project. The exhaust on my 380 is shot. The pipes have been cheaply 
repaired in the past, the resonators have large holes, and there are holes 
everywhere in the piping. I have found a good shop to do the work but I wanted 
to run my idea by everyone first. 
It has the euro log manifolds so those are going to stay (just sandblasting and 
powercoat - jethoting is a little pricy), I want to remove the old BMW cats and 
resonators. The pipes would run straight back with an X-pipe, finally leading to 
the original muffler (Until I find a muffler I like). I was planning on running 2" 
tubes, is that too big? Also, does it matter how far the X-pipe is from the 
manifolds or muffler? I was planning on putting it in where the resonators are 
now. 
- Everything will be mandrel bent stainless, I also have the dual intake installed 
if that needs to be taken into consideration. 

Any advice would be awesome, thanks. Jas
