i have Aftermarket Bolt on Headers that will connect perfectly with my Cat-Back Exhaust and just need some guidance to get them installed correctly for the cheapest amount, i have a lot of quotes for about $1000 from shops around my area but i have reason to believe that is too high as i could do it myself for free just the cost of time and effort. need some guidance please.
My car has 31000 miles.
My car has a manual transmission.
