So im thinking about my next set of upgrades. Ive read about the EGR delete kit and that it saves 40 lbs of weight but there isnt much to gain in performance correct? Also the BD Manifold does it change the sound of the exhaust? I read about it at the DP but the change in sound wasnt really expressed. I know there isnt any noticeable performance upgrades with the manifold so lady and gentlemen im all ears.
