How does this compare to the G35 install of cats/test pipes? Everyone whined about how hard those were, and I did it at home in just a couple hours with hand tools and some patients.

HP chart for BERK
Here is my comparison shot of before and after BERK HFCs. This chart only shows the HP gains so I will need to scan the sheet the printed for me to show you the TQ gains. Just so you know 13HP/6TQ gained also it cleaned up the Air Fuel ration a ton on the mid to high RPM range. I wish I had a before printout of the Air Fuel ratio to show you guys. Hope you don't mind me posting this to your thread Max.

Btw
When they first started the engine up and hit the throttle it sound VERY raspy to the point I really wanted to take the dang things off. After the smoke cleared (literally from the HFC being new) it sound great. The rasp was gone and it was deeper sounding. I don't know about anyone else how has bought these and installed them but it does sound a lot different to me. It is like night and day, and I only have the stock exhaust.
