February 8, 2010I recently gave my 2001 SuperCrew with a 4.6 to my son. It has a 70 series Flowmaster on it.. a SI/SO... single muffler, with the stock tailpipe on the truck.
My son wants to install a Super 44 that he got for xmas (for his old truck, now sold) onto the Supercrew with the 4.6.
Question is... will installing the Super 44 on the 4.6 cause any noticeable loss in power and/or torque?
Other than Bousch platinum plugs and a K&N cold air intake the motor is stock.
Thanks in advance.
