The left one was half unscrewed and both were easily screwed in/out by hand. The technician obviously didn't pay attention to make sure everything was secured. Tightened those and went for a test drive, and man does the exhaust sound sweet!!!! And, of course, no more rattle!

Yes, I had the Invidia exhaust installed before. Ran it for about 600 km before the HFC install. I definitely want to get my ECU tuned...likely Cobb AP. That would be cool to get the same map as yours, since we have the same equipment. I read your other thread and 25-30 HP and lb-ft gain after the tune is crazy awesome, man! I wonder if I should get an e-tune from them or even a dyno tune somewhere to get the most gains (as each car could be slightly different, we live in different climates/altitudes, and buy different gas)???

Also, thanks to Nissangeneration of ERZ (forum sponsor) for suggesting that I should check the O2 caps. If anyone else is interested in a set of ERZ HFCs, definitely fire him a PM.

BTW, 250 km so far and no CELs.

How did you find the exhaust note after the HFC were installed?

It just purrs! Exactly as Bluestyle described it. Nice deep throaty tone...just how a sports car should sound. Louder and richer than just CBE alone, but mostly when gunning it. Not much louder when cruising. I find myself driving with the windows rolled down most of the time just because it sounds so good.
