Togo Posted June 8, 2006 Share Posted June 8, 2006 Im considering long tube headers.If I do I will have to elimiate the cats on the Y pipe.Will the will the secondary cat be enought to pass emissions inspection? i believe so - i had the pre-cats removed on my '94 mustang, and my sister had posession of the car at the last emissions test, and she didn't call me to yell that it didn't pass!
