i dont know max. i think you have to. we had to on mine.

 

Not on mine... guess my guys just had that perfect tool....

I helped with the install so I knew what went on...

All we had to take off was the driver side air box...

 

We didn't have to on mine either. Just had to use a short socket on a long extension and a breaker bar to get it loose.

 

Having the right tools = FTW ...lol

 

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.

 

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.

 

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.

 

very cool, nice gains.


Make a new thread w/ the hp/tq dyno... i'm sure people would love to see it front and center.

 

Very Nice! We have the same setup, so this gives me a good idea of what gains I am getting as well.

 

No prob here...glad you posted... but I would make your own thread just to get the word out better...

 

Fine Max....geeezzz

lol

 

ppssshhh... I just want people to know about the nice gains some High Flow Cats make,...
