exaust and air intake question

Hey I just bought a pacesetter cat back exuast and vibrant performance cold air intake and was wondering after i install these if i will notice an increase or decrease in gas millage, Just thought that someone might have noticed. Also will there be much of a horsepower gain, assuming everything is done right? thanks

Sorry its a 1996 Cavy Z24

If you drive like you did before the mods, theoretically you should get better milage. However, are you going to drive good when your car sounds good like that? Hell no ;). Even so, the difference would be minimal, surely not enough to save you much money at the pump. I'd guess with a catback and intake you'd be looking at about 8-11 hp, kinda hard to say.

X2 :iagree:

yeah what they said... if you drive it to hear it..then down goes the mpg. if u drive it like before..then it should... i put mine on and wanted to hear it..yeah..she droped quit abit. from 27 mpg to..i think i was getting 19 to 20mpg. minor tho.. the sounds worth the 7-8 mpg i lost.. guess it dont help running 3rd gear down main street at 40 around 3grand...

im the same way...lol i found that 3rd gear is the loudest for my exhaust so i keep in in 3rd till about 3200 RPM and let off the petal....sounds bad ass to...
