Any thoughts about validity of Exhaust Depots claim for added hp and better flow with their 2.5” y-pipe. I have read Mike’s thread on back pressure myths and related comments and this seems to make sense.

 

I put one on her G37. What would you like to know?

I also have an extra one in the basement I need to sell. Never installed.

 

do a search on "exhaust depot y pipe". there were 3-4 thread back in '09 with relevent info.

 

thanks, that was helpful. I get very frustrated with the shotgun search function and need to be more patient probably.

 

I have one on my car. Gives a noticeable mid range increase.

 

The first one you got from ED???

Seriously!!

 

Didn't even register on my butt dyno after install, but it did address my Tanabe's being too quiet. Post tune I came out with some nice gains dyno'ed and felt, can't say what % the y-pipe played in that though. Had Tanabe's y-pipe been available I'd have probably gone with that instead.
