What would be your budget?

Alex821

$400 after BBK shorty headers $300 and intake $150 and also i already have PI inatke manifold with heater tube just need to install it

If it were me i'd forget the shorties and CAI, and do long tubes with some gears and a tune.

The thing is that i have stock exhaust and i don't know what the smog guy will tell me when i get it smogged if i have long tubes since i'd have to move catalytic converters

mrtstang

Oh yeah i see that your in Cali now. You guys have some crazy rules out there lol. Well i still stand by the gears and tune though.

Unless you "know a guy", you might not want to touch the exhaust. I think we do have some members from California that could help answer the question about exhaust.

+1 on the gears and tune. I would also pass on the CAI because that's not going to do a whole lot for you except look nice under the hood.

Alex821

Yeah CA isnt the greatest state when it comes to "smog" but if i get the shortys will it effect the smogging in a bad way? BTW it's a automatic what will the tune and gears do (performance wise) if i dont have much bolt on?

mrtstang

The auto will respond even better to gears and a tune, even with limited bolt ons. Gears essentially manipulate the torque and horsepower curve to into the power band faster...hence quicker acceleration. A tune will allow you adjust the speedo for the gears you choose, firm up your shift points, read codes, adjust timing to allow for the use of premium fuel, and a few other odds and ends.

Alex821

Awesome thank you for explaining that. what gears do you recommend? like i said as of right now its all stock and all i have is a PI intake manifold that i need to install. how much is a tune like the one you explained and should i switch over to premium gas?
