Either way I made more with the Gintani Catless xpipe/Stock Muffler combo! I think with the Borla back on or another HFE, I'll pick up a bit more.
Here's the results in all three CF's, I gained around 15 peak WHP, but as much as 22 whp gains at spots throughout the P-Band!

DREW.
are the number increased just on the x-pipe alone? that is an awesome gain for just a x-pipe swap!
a big congrats!
