I had and loved the sound of my DT center exhaust, but then I installed the DT header and it was really loud, so I installed the DT super quite.It is louder now with the header and the DT super quite than it was with the factory manifold and the DT center exhaust.It sounds really good, I think it's almost a little too loud now,I thought I would let everyone know in case anyone is planning on installing a header.
