Started with a K&N cai with a throttle body spacer from airaid. Gave it a nice throttle response. With the JBL shorty headers it helped with some top end hp. Sound didn't change until I got a free flow magnaflow muffler. Now it has Alot of top end power. Very happy with everything. V6 4.3 need all the extra hours.
