There are already other longtube headers available for the 2011 Mustang. Pypes chose to take it up a notch. Their 2011 Mustang longtube headers may not look like the other longtube headers out there but after you feel the performance, you won't mind one bit.
Testing of these new long tube headers has shown a 27 HP gain over Ford's stock headers. But even more impressive is a 58 HP gain after replacing the stock exhaust system with Pypes Headers and a Pypes Super System. |
