have an 08 500 with kenne belle 2.8blower with just tailpipes ive heard headers such as dynatechs are worth 30horse was wondering about americans headers i understand the boost will drop a little until ire pulley it.

 

I'm not sure about the horsepower gains, but the reason you would drop boost is because your restriction would be lower due to a better flowing exhaust. Not a bad thing at all. Less restriction equals less air buildup and less boost. You're still getting the airflow from the blower, it's just flowing better.

 

American Racing headers are top notch fit finish and quality. Plus they make some serious numbers. If you call or stop by ask for Nick, tell em you were referred by his old friend Eric with the 10 GT500................he will probably cut you some slack.
