2nd Gen Non-Engine/Transmission Yet another 5" exhaust/exhaust brake question

[NPloysa]

Ok,



Is anyone running a 5" exhaust setup with a remote mount 4" inlet/outlet exhaust brake?



I am wondering how much less efficient it would be having that 4" restriction in the middle.



4" would suffice for me and where I want to go with power but 5" looks so COOL!



Any thoughts? Or would it just be better to run the brake at the bottom of the 4" downpipe and then open it up to 5"?



Thanks, Nick
