Porsche 997S Exhaust Sound Check - Europipe and More

Nice. but who much is the gain in hp & torque ?

[RonDeKiller]

Maybe 20-50 bhp. Many vendors claim a lot more but be skeptical.

Thanks for the answer but I believe that 20 hp may be true and reasonable as a gain from the exhaust but 30, 40 or even 50 hp is a number that begins to be difficult to obtain without any cpu reprog. or inside the motor work. (crankshaft, pistons, e.t.c.).

I usually tell people that exhaust changes need to be done in conjunciton with intake and ECU tune. Those are the three fundamentals and lowest level tune. Then maybe slightly higher numbers can be found. I'm pushing nearly 200 bhp over stock with a supercharger and several other mods.

[boxserpent]

Thanks. I totally agree with you.
