Those with Tanabe DP's....
 

Do you guys have any issues with the Tanabe DP's as far as restricting power? I have the concept G Blue TBE and I've been told that it could be holding a few horses out on me. Seems like it does have an extra bend compared to a few other brands. Should I swap this out with another DP or stick with it? Thanks guys.

they should flow pretty well. but a little bigger in size will help your hp numbers. according to what I've been told (don't quote this) the 2.75" actually helps keep your tq numbers up a little more. So you might see a slight drop in peak tq. this is only what I have heard, but I have not seen any proven tests.

With the ACD, the 2.75 gives better clearance. I've heard that the Perrin 3" has the best clearance of all 3" dp for the ACD equipped Evos.
