Exhaust and cold air intake

[Erics2010Ranger]

I have heard both yes and no on going WITH exhaust and cold air intake. What is your opinion or experience with running both? I am considering MBRP for exhaust and K&N for the intake.

Does your engine have a MAF? The oil from K&Nd tend to frig them up. Also, cold air intakes, I personally believe are a waste. I'd go OEM filter, especially on a 4.0, I don't know about any of the other ranger engines. Also, don't know much on exhaust, hit, I think youd get more from that than you would from the CAI.

You already have a cold air intake, a real one. If you want some shiny tube under your hood, go for it... But it will not gain any power over the stock intake. At best it will actually loose power.

Secondly, what do you mean by "exhaust" ? A cat back system? Headers? Full exhaust? You may gain 3-4 horse power from a full on exhaust system. And loose about 5% fuel efficiency.

Yes I mean cat back for now. Maybe Henderson the future.

On that engine none of it is worth your time or money to do. The cat-back system maybe, if you need an exhaust already, or if you want to change the sound. From a performance standpoint you have nothing to gain.

I have to agree totally...

Those two modifications never made the list for me. I think what you have is really all you need. I will say that when my factory exhaust goes I will be looking at the cat back systems that are available.

You already have a Cold Air Intake, and a 200% air filter.

Your current Factory exhaust manifolds are scavenging for best power in mid-RPM band.
You can change to low-RPM band manifolds for better acceleration from standing start, but do lose the mid-band power

Thats the way scavenging exhaust systems work, you have 3 choices
Low, mid and high RPMs bands, you get one

Scavenging exhaust manifolds cause a lower pressure at the exhaust valves at a specific RPM, this is done by using the Velocity of the exhaust coming out of each cylinder in a smaller pipe and dumping it into a larger pipe size.
The calculations for this are numerous, lol, but suffice it to say they are accurate and specific to each engine model.

Ford has been using scavenging exhaust manifolds since the 1960's on some engines, its FREE POWER, since the late 1970's pretty much every engine from any car maker uses scavenging exhausts.

Ok well that pretty much does it. I appreciate all the responses. I was pretty much just looking for a different sound with some performance added but I think I will just wait until it is time for new exhaust.
