ignition sys
I am looking to upgrade my ign system wondered what others are running with a stock 305 and upgraded cat back exhaust any help or suggestions would be great thanx
To be honest you will most likely notice very little if any HP differnces. I started with a MSD coil in my RS then went for the 6AL. The coil help a little on the high end and I didn't notice a darn thing with the 6AL.
