ok i'm thinking about doing a straight pipe on my 96 accord ex...about how many horses would that add to my car?

 

the only way to add horses to your car would be to install a hitch, buy a trailer, and tow them. The only things adding a straight pipe will get you are a ticket and a failed inspection. Consider buying a cat back exhaust, there is plenty of info on different brands on here.

 

Steer is right, a straight pipe will get you nothing. Unfortunately, a cat-back got me a failed inspection and ticket threats anyway.

 

You will gain 1000 hp, to the wheels.

Just buy a quiet cat back like an Apex'i WS2 or Greddy SP2.
