Bassani 3.7L Mustang Full Exhaust System

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.

Bassani High Flow Cats 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.
Bassani Race Pipes on a 3.7L Mustang 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.

resonators  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.
