i just got my acura white 4dr gsr i love it. i put a cold air intake and exhaust i got 21/4 pipe high flow cat and magnaflow muffler. MY question is i feel it lost power does has any one herd of this before. the exhaust is LOUD i am going to put a resonator on. i just paid alot of money and i feel i should of just got the air intake i cant even feel a difference with that either but i know it has to help. plz help i think maybe it is the high flow cat making me lose torque i am not sure though.

 

With the kind of setup you have, you might be feeling a loss of torque in the midrange, but will gain back and surpass the loss in the upper range...

If you never go into VTEC with that kind of setup, you will never really feel a substantial increase in power, or maybe even a loss...

 

yup....exhausts tend to gain the power in the upper R's and drop a little in the low and mid range. The intake itself should gain pretty much all around (mostly in the high end). Reason for all this is cause our engines need back pressure. When you make the exhaust piping larger, you loose back pressure...but it increases air flow which gains you power in the higher RPMs. You didnt waste your money. As you modify your car more these mods will become more influentail (i guess thats the right word to use) as to how much power you are puting down.
