Description
Improves Exhaust Flow. Increase the power at the rear wheels of your Shelby GT500 by eliminating those power robbing catalytic converters with a Stainless Works Off-road H-pipe.

Superior Construction. Manufactured from T304 stainless steel tubing for strength and durability, Stainless Works mid pipes are mandrel-bent for superior airflow - so there are no kinks to rob you of power.

Application. This standard length Stainless Works Off-Road H-pipe is designed to fit the 2011-2014 Shelby GT500 Mustangs with either the stock factory exhaust manifolds or aftermarket shorty style headers installed.Technical Notes.

Good things: fitment, finish, material and delivery. Noise: very loud without cats and straight piped all the way out the back; but, too much drone inside of car. Will have to added some mufflers to tone ...

Overall I'm happy with the exhaust it is more raspy at high rpm than I would had liked. I put this on and kept the original axel backs and original headers. I did this because I didn't want a drone on ...

    H-Pipe

    Good things: fitment, finish, material and delivery. Noise: very loud without cats and straight piped all the way out the back; but, too much drone inside of car. Will have to added some mufflers to tone it down just a little. Bad things: no plugs were supplied for the extra oxygen sensors locations and spent (3) hours running around town trying to find plugs that would fit properly.

    Overall I'm happy with the exhaust it is more raspy at high rpm than I would had liked. I put this on and kept the original axel backs and original headers. I did this because I didn't want a drone on the hwy and it's there but it's perfect. You can have a conversation in the car with out a problem. Installers beware there are two extra O2 sensor holes that the car does not have sensors for. You need to buy bolts to plug them up with I was upset because I had already taken my OE pipe out when I realized and had no other car to go get them with. Stainless works should provide the plugs or at least put a big orange paper in the box notifying you that you need to get additional parts before installing. Also this mid pipe makes your tail pipes stick out about a half inch past the bumper. It doesn't look bad it actually gives it an aggressive look but just FYI.
