exhaust. For any mods that you add into the car will only make the miledge go down.

 

Well hello welcome come to Club Lexus, I hope that you are enjoying your IS300. Gas mileage is subjective, driving style, trip times, and gas are all variables in measuring your gas mileage. As mutantblac said the more mods you have the worse your gas mileage gets. If you are curious as to what others have done to their IS300 I recommend that you go to a site called My.is.net (formerly IS300.net) there is alot more information about performance upgrades in this website.

Good Luck Modding
