Just to inform you before you buy a exhaust. A best exhaust for a evo will be LOUD. If you want the most power out your set up then I suggest running a test pipe with 3" downpipe and Greddy Ti.

I have the buschur TBE and it work good and make good power! But its not quiet. I just don't want people to keep making the post, " my exhaust is to loud " lol.

 

c'mon now...
I run the Buschur TBE - test pipe w/ bullet muffler, its only LOUD at WOT
Buschur and never go back!

 

Works turbo back. Not very loud until you get on it, and full 3 inches back.

JDM exhausts may boast 80mm (greddy ti) but take a look at the flange where it connects to the cat. Thats NOT 80mm, thats a neckdown. Also known as a restriction. So makes the most power? Nope. If I wanted max power, I would go with AMS or Buschur. The helix is pretty much straight through as well, but just drones too much on the highway for my taste.

Blitz Nur Spec w/ the neck down removed.....

 

it necks down to 3"

 

/shrug. I made 20 more hp on the same dyno on the same night with the same mods. (We both had works drop in and works downpipe) Only difference was instead of works catback he had greddy ti. I wasnt too impressed.
