I have a 2005 Mustang GT with 50K miles. I will be installing LT headers on it when it warms up. Since I need to remove the starter to install the headers, do you think I should replace the starter with only 50K miles or leave it in? A new starter runs about $130. The car is no longer a daily driver and will only be used on weekends now. It also has a Edelbrock supercharger which I installed last year.
