Unfortunately, even when I had the catless pipes built for my car (1st one to do so, and
NOT made by PPE).....
I, just like 4DRHTRD, didn't have the luxury of doing a pre/post dyno.
Now, I still have my original set of OEM downpipes, but I'm
NOT willing to go through the fk'n hassle of reinstalling them, then driving somewhere that has an AWD Dyno, dyno it, only to head back my friend's shop to remove the OEM's once again, and then reinstall the catless downpipes a second time around.
Screw that. No offense. But I'm on 4DR's side on this one.
Good luck to all those jumping in on the PPE band wagon!
