 This full 3.7L Mustang exhaust system made around 30 RWHP on my supercharged 3.7L V6 Mustang. That is about right. When Bassani made a 5.0 V8 Mustang Exhaust kit, it made around 40 RWHP.
I started to look at taking the factory exhaust off and quickly discovered it would be very difficult without a lift. So I had the guys over at MC Racing Install this full exhaust system. |

I later installed some Bassani High Flow Cats to take the edge off of the highway drone. |
 |
Here they are compared to the race pipes. They are small and should not be very restrictive at all. |
 |
There are 4 band clamps to pull. Two flat and two V. Then the two AFR sensors.
One side pulled right out and the other was a bit tight. Once you have them both loose the pipes will drop down. I used a jack stand to hold them up just below the header level. |
 |
Drop them down and then twist them out or tap them with a rubber hammer. When you put them back in you have to push them a bit deeper so you can get them past the lip of the headers. Then tap them forward and put on the v-clamp. Overall you can swap them out in about 1 hour. |
 |
Last I added a pair of resonators to mellow the sound without cats. They create a grate burble on deceleration. I like them a lot. |

Its absolutely the best sounding 3.7L Mustang exhaust kit out there.
