The headers you have fit your exhaust and really are top notch quality to match everything on the car - the TTI's I have were a new experience in putting the starter in - without the lift - it took me 6 hours to put the headers on - with the lift it takes me about an hour with my son helping with the starter. My headers were around $1000 delivered and another $450 for coating (Black Ceramic)

Looking at the new suspension you have - I am guessing the TTI are going to hit near the same place - that suspension really comes in quite a bit
