97 3500 4wd. installed a #11 tst fuel plate and a y on the exhaust pipe and ran 2 3 in pipes out the back. i now have a lot more power and torque. today i lost power steering and brakes. i removed the power steering pump and vac pump. the tits inside the coupler were sheered. is this due to the mods i made on the truck? does anyone offer a beefier setup? thanks.
