Well I suppose my question can be answered here aswell. I have a full Tru-bendz SS 2.5 inch cat-back and Tru-bendz SS y-pipe. I also have the strait pipe, meaning no cat. But I have the stock manifolds on the car. I would like to put the MSDS headers on but I'm worried about the noise getting any louder than it already is. Anyone with similar setup would be most helpful. Thanks
