im on here doing research for my friend who doesnt have internet. he just got and 06 3.9 monte carlo and wants to start working on it. I personally own an STI and know nothing aboutmonte carlos(except that they arecapable of some serious power). any help from the members on this forum is greatly appreciated, and i look forward to learning some new stuff about these cars.

RE: newbie
hey, welcome and welcome to your buddy that doesn't have internet
whats an sti?? (that may sound stupid but i've never heard of one)
as for the power i'm not sure if they're are any mods out for it yet...i know there's a few guys on here that have them...and they've been sayin there's not much yet
good luck though

Matt: I've been doing some research, but unfortunately, not much has come out for the 3.9L yet.
First is the obvious. Have a Cold Air Intake custom made, some alum bent tubes and a universal cone type K&N and voila.... CAI.After that, exhaust. Unfortunately if you've heard the 3.9 exhaust, you know that there isn't a heck of a lot of room for improvement. First thing would be a high flow Catalytic converter, then you might want to look at replacing the resonator with a piece of straight pipe.after that, the mufflers aren't much of a bottleneck, but they can be replaced for better sound. If you don't increase the tubing over stock, then you shouldn't lose to much low end torque, but you will lose some.One of the beneifits of the GREAT 3900 is it's torque curve (see attached picture). This car has 90% of available torque from like 1800 rpm and up! less backpressure means the torque will increase overall, but it won't come available until later in the RPM range.
After that, there's not much. Re-tuning will see some benefit, but the tuners that are out there are one, pricey, and two, they fit such an incredible range that I wonder about the true benifit that can be had from them.
Plus, the stock transmissions are rated for like 285 HP, anything after intake, exhaust and tuning, could overpower and start to seriously effect the transmissions life.
