Intake and Exhaust worth it?
 
Since Superchips is still currently working on a programmer for the 2011 would getting just an intake and exhaust be worth it?

For the intake should I go with a whole kit or just get a drop in? If I got a kit I was thinking about getting this one:

As far as exhaust goes I would get a Magnaflow single in with dual out.

What I am wanting to achieve is better performance before I hit 3000rpms (feels like a turbo kicks in when I hit 3000). I would also like better fuel mileage. Would getting these things achieve what I am looking for?

Or should I take out the 3.55 gears and just install the 3.92 gears since about 75-90% of my driving is city anyways and there are some hills along the way?

Intake and exhaust will help, but it's not going to make a day/night difference. If you plan on getting a tuner for sure once they come out then it would be wise to do intake/exhaust. I use the airaid jr kit http://www.airaid.com/ProductDetail....ductID=300-725 and it works great. It fits our trucks, you just have to buy another coupler and it fits perfectly. I bought the pieces separate (about $90 on amazon for the tube and about $50 on ebay for the filter and I got the oil free filter). Magnaflow would be a great choice for an exhaust.

The intake and exhaust will definitely help but the nature of a small displacement engine is that you have to wind it up to get some power. Gearing would probably be more noticeable honestly....and I'd go with either 4.10 or 4.56 if I were you...

Would love to go with 4.10 or 4.56 but with the new axle they put in the 2011 its a waiting game for new ring and pinions. Thanks for the info about the intake and exhaust.

Oh I see. Could you find maybe an RT axle with 4.10 at a wrecking yard and swap the whole axle? Might take some time to find one...but may work. I assume they are interchangeable as a whole unit.

I don't think adding these 2 will help w/fuel mileage. I think it will do the opposite. Any one else now this for sure?

It will help a little if you are easy on the gas. They will make the engine more efficient...go for it!

snrusnak 09-27-2011 08:05 PM

yeah they definitely won't hurt as long as they are done right, and they should help slightly, but I wouldn't do them as mpg being the prime reason.

Intake and exhaust are always good mods to have. Almost all engine mods that come later will perform better with a better flowing exhaust and a good intake. Go for the full intake over the drop in filter.

Almost any internal combustion engine will make more power and efficiency will be improved by the addition of a freer flowing intake and exhaust.

The problem with mileage is that you like that new found power and can't keep your foot out of it. :D

But, yes, they will help in both categories.

And don't expect much with a drop in. If your goal is to improve power and MPG, do a full cold air intake kit.

I've noticed that too..after about 3000 rpm there does seem to be a boost in perfomance...why is that?
