Test Pipe
 

What kind of power increase can i expect when I install a test pipe (83 944)?

How loud is it, anyhow?

made the inside of the car quieter because there is less turbulent air right below the shifter. horsepower? i dunno, i've heard 3Hp or so, maybe 5 or 8, depends on other factors.

good luck!

I would guess around 7hp on an otherwise stock 944, given that your muffler isn't falling apart.

Not so much at full throttle, but mine felt like it was louder when backing off from high rpms.
