Or surrounding area. Anyone in here have a stock axleback or exhaust system they are wanting to sell. Ive had my flowmaster axleback exhaust put on and lost about 40 miles to a full tank of gas. Ive changed out my spark plugs and put a drop in kn filter in and Im still at a loss. No one can give me a straight answer as to why so I am thinking of going back to stock.

Thanks.
