Purchasing full exhaust soon. No problems right?
) this spring but want to make sure everything will fit togeather right. Plan on getting a typical set of coated Pacesetter headers, TSP catted Y, Borlamouth, possible cutouts later. I thought I read somewhere that the pacesetters have no problem matching up to the Y but will the Y bang on the floor any? Keep reading about the pacesetter Y's banging and didnt know if the TSP Y's have such issues. Also will I need O2 sensor extensions. And a tune isnt necessary after headers correct? Doesnt hurt to have one but isnt needed right? THANKS for any info.
