20+ Horsepower from exhaust - 986 Forum - The Community for Porsche Boxster & Cayman Owners

To get 20+ HP from this car you will need an exhaust, cats, headers, intake and an ECU reprogram. Then you will get close to 30HP more. Just a muffler? Never!

Sorry but i think you can.
A basic induction kit goves 7-12bhp

A dyno can settle the score. Could you cut a deal with the supplier that they will refund your dough if you can get close to the 20 they advertise?

I'll eat the muffler if it produces 20hp alone. There's no friggen way! I think someone on another board has already dyno'd a bunch of aftermarket mufflers. They all produced from around +3hp to -3hp. Also keep in mind that usually any gains are up on top at the expense of losing torque down low.

I'll help Lux out and eat half the muffler that makes +20hp. No way no how with just an exhaust alone. :dance:

I spoke with a tuner in Sacramento today. They have a dyno and tune european cars and the like. They sell the unichip. He said he can make hp in my car. Custom mapping after my mods are installed. I also found this interesting dyno chart on Unichips website. They have a great rep. Maybe my goal of 250 is doable (I am starting with 225).
