Installed Berk on my 2K2 6 speed. Sounds and performs well, but if I go past about 5500 rpms I get a nasty egg smell. My guess is it's pushing thru so much air the cat doesn't have enough time to clean it? Anyone else notice this?

 

it might be just stuff on the inside of the intake burning off as it goes through, probably needs a break in period. like how a brand new exhasut smells after you install it and start fo the first time..

p.s. I feel bad for people behind you...
