Schumaker vs TTI Headers

440-200 headers. 2" primary, 3.5 collectors. Exhaust is TTI 3" front to back with an H pipe and Borla XR-1 SS mufflers. It goes right to the bumpers with double rolled slash cut tips. The factory tips are restrictive and also change the sound do to their size and design.
Thanks for the info, not worth change to me from the Schumacher headers to the 2" TTI's for only .4 of difference compared to what my car runs now. Plus I like the room around the motor.
