The installation was an absolute nightmare and almost brought me to tears. Taking the bolts out of the stock cats was near impossible. I've drenched the damn thing with the bolt lubricant and it still brought me to my knees. It literally took me 5 hours to take all the bolts out. On the bright note, Intalling was a breeze. TP was slightly misaligned, but the HKS was near perfect

SOUND - Initial start up - it was completely horrid, raspy and just plain nasty. Drove around a few miles to settle in.. and it's a bit loud, but oh well
test pipe is doing it's thing, I guess

PERFORMANCE - Can't really say. I don't see much of a difference, which maybe a good thing.. meaning, it's keeping it's linear power band (didn't feel any sudden power drop). Also, I've gained some fuel efficiency by couple of miles

ISSUES - I have the newer version of the resonated Helix test pipes that AREN'T suppose to throw a cell, but it did. I'm drive around for a week and will go through the no fouler route, if it doesn't go away.

go to autozone and borrow their obd2 scanner, it's free. Check the code to make sure if u need them in the first place and then erase them.

Does it rasp once warmed up? Almost all exhausts rasp w/ test pipes when cold. I rasped w/ stock and nonresonated cold, but it sounded clean and nice when warmed up
