whats a good exhaust system for an 03 xterra that increases hp but quiet as well?

Answer 1

I actually have had the same make and, the Xterra only averages 250 miles to a tank of gas. I got out of it in 6,000 miles.The pathfinder handles, has the h/p and drives like a car. A exhaust system will not increase h/p with out more noise, even headers and Flo master mufflers will drastically increase your noise level. You can help some by a K&N filter Charger. I actually have it for sale for $75.00 and, the cost will be about $179.00 plus tax new . It will give you about 8% more horsepower and, increase your mileage 3-4 MPG.
