unorthodox crank pulley and exhaust system

[Russel]

Hey Guys,

does anyone have an unorthodox crank pulley on their 1st gen altimas? does it give enough hp? any problems?

question on exhaust. i upgraded my exhaust to a high flow cat converter(almost test pipe) wiht a 2.5 cat back straight through exhaust pipe with a round aftermarket muffler. it sounds too loud and need to quiet it down wihout loosing hp. any suggestions? right now i have to put in the silencer but i noticed that it burns a lot of gas. i appreciate your input.
