Irwindale requires mufflers. And its best to check the place out first. The return road around the oval is a bit different. Goes thru the roundy round pits and they practice thursdays also. Great place to race. Great staff,plenty parking and the stands are close to the track with the return road between them. Plus you would like to say you raced there as this might be the last season. Place has been sold. Another one bites the dust!
