I recently installed an OBX Racing POP Charger and Magnaflow exhaust in my 1997 Maxima Automatic. I noticed really good gains on the low-end, but it feels I've lost some power on my high-end. Simply, jump starts are great but high speed acceleration sucks! Any one have any comments or suggestion on this?

 

Hmm that's odd, the air filter should help some up top as well. I know the CAI has a loss of power when compared to a pop uptop because of the turblence caused from the pipe bends.
