>> 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
