installed my DP and test pipe!!
it s amazing to see how many people on this forum that dont know what they are talking about. Exhaust doesn t need a ecu reflash at all.
back to the original thread, yes after installing my dp and highflow cat, i could feel a difference in power.

OMG, this car pulls like none other! i had not idea i was gonna get this much of a difference. spool up is better, im at 7000 in no time! and on top of that, it sounds bad ***! over all performance, i give it a 10!

congrats!
no CEL?
ECU flash isn't needed but it would definitely help. I have an AVO catback and HKS downpipe. The car didn't really feel any different other than it has an exhaust note. I figure with a MBC and flash I will feel it.

I noticed a difference when I went from stock to megan TBE with test pipe.
Faster spool up with more whine (even more whine while the undertray was removed)
Boost seems to go from 22 psi in 3rd down to 19 psi, whereas it seemed to be 21 psi to 18 (though that might be due to cooler air in winter, not sure)
Go through 1st and 2nd gear like a shot
My ghetto 02 fix is working well-no CEL's, but it is not very pretty.
