personally u might get some minimal gains but the heavy 18's are gonna slow you down...

of course you'll gain a little HP from your new exhaust over stock..... a muffler does nothing.... all its good for is making noise.....

yeah you'll get better performance with the Greddy Evo. but even better performance with the Apexi N1 Catback.

All your mods are for performance even the kit! the only thing slowing you down are your rims.... sell them and get some NOS.... jk... but like i say in al lthe threads... NOS is worth every penny. Good Luck with your car and Happy Modding!

You will get about 3-5hp from the intake and probably another 5 from the pulleys.

You want to notice a real gain, w/o nitrous, pick up a 4-2-1 header. With my mods I smoked a 5.0 Mustang by 2 car lengths (off the line mind you). Even the 5.0 driver couldn't believe a 4 banger beat him.

My mods:
AEM CAI
AEM VAFC
Matrix 4-2-1 header
Greddy EVO

Coming soon:
AEM pulleys
ZEX Nitrous kit
NEUSPEED ignition wires

You don't get any horsepower gains from pulley's. You only regain the power you lose when you run the A/C and stereo. The only noticable thing is the engine rev's faster, that's it.

Exactly. You will get a 5hp gain to your FWHP number

I heard 4-2-1 headers are good for midrange power and daily driving, how much would these be and what kind of gains are expected. I have a 00 base with AEM CAI, AEM pullies, Thermal R&D

He means APEX i, slight typo?
