I know there are a lot of people like myself, especially in CA, looking to upgrade their Evo's exhaust system without touching the cat and/or sacrificing daily driveability by swapping in a loud setup. So for about a month I've been searching these boards and the rest of the interweb for the best, quietest, cleanest CB exhausts available for the Evo 8. Here's the list (in no particular order) that I've accumulated so far. If I've posted any incorrect info please let me know. Also if I've forgotten a setup please post it up with a picture and approximate price range.

great post bro

 

Quietest will have a (1) muffler and (2) one or more resonators. You can save yourself some $ and remove the flapper in the stock muffler of your stock cat back exhaust... Just a thought.

 

whats the difference between the Fujitsubo Legalis and RM01A?

 

Still won't do much as the path inside the muffler won't be smooth. Not to mention the stcok exhaust has too many bends and is small in diameter.

 

Don't forget the AVO exhaust.

 

don't forget hayward & scott exhaust.

Steiner....ohh i am so honored you used my JIC Spartan pics on my EVO lol!!!

 

Add Apex-i World Sport to the list.

 

Ohh I also wanted to add that all the power gain is from removing the OEM cat. I'm running a 2.75" Espelir DP, a 3" stainless DP, and the JIC Spartan CB...and even then its still QUIET even at WOT w/o the cat!!!!!

 

Another thing - the factory exhaust is very heavy. I bought my EVO used, with Buschur's 3" turbo back - no cat and magnaflow muffler installed already. The previous owner gave me the old exhaust pieces. When I went to get them out of the trunk, I nearly wrenched my back.

 

ANYbody got the RSR ExMag Exhaust? with more than 400whp?

 

You must include the AVO exhuast on this thread. I am also suprised I don't see B&B exhuast on here as well. A third option tould be the new line from Tanabe, the one with the "bigger" muffler and different packing material. ANy of the above would qualify as a quiet exhuast.

 

I (((hear))) the Supersprint is quiet and made well. http://www.supersprint.com/homeuk.htm

 

The Buschur 3" Magnaflow cat back sounds nearly stock and performs absolutely awesome! 12.18 @ 112.8 with only a few mods!
