Exhaust and Intake

I am going to order an exhaust and an intake for my jeep on monday. Anybody have some suggestions. I just want a cat back exhaust right now. I have the 4.0, and i know nothing about putting an exhaust on a wrangler, never done it before.

I've narrowed the intake to a brute force, k&n or an air raid, but as for the exhaust, i have no clue.

my buddy just put on a brute force and loves it...plus its cheaper then a k&n...and as for exhaust you can go with flowmaster, banks power, dynomax, or borla...those are some very good popular names that make cat back exhausts...i have a flowmaster cat back on my jeep and love it...it sounds freakin awesome and i got very good performance

I was thinking about simply buying a flowmaster muffler, then leaving it like that. Or I also looked at the Dynomax, i found one for 200 bucks, cat back. Also, from what i have found the cheapest i can find the Brute Force is for 230, while i have found the K&N for 190. Just wondering if anyone actually knows if one is proven to be better then the other, because if not, i'll go with the cheaper of the two.

I have put on the Flowmaster, and it really helped with getting rid of back pressure. As far as the cold air intake, I haven't made up my mind. This is why, read this thread.

cold air intakes

you do not have to buy a full air intake...you can just buy the actual intake without that fancy tubing (which doesn't look bigger than the stock air tube anyway) and just the intake itself with the stock tube will help...and you don't have to buy a full cat back exhaust...you can just buy the muffler and a tip if you want a nice lookin tip...the cat back gives new tubing and some companys give new 2.25" tubing which isn't bigger than stock anyway...for example, my muffler man said if i ran duals that i would of course get new pipes...and he said that they would be 2.25" which is the stock size...and duals wouldn't fit so i ran a single with the stock tube...so my point is that even if you do get new tubing it might not necessarily be bigger...it might be the same size that is on there...which means theres no point in buyin it cuz its not bigger so theres no more flow...so you can keep the stock tube which might be as big as the new tube the cat back would give you and just run a flowmaster muffler and tip if you want...sorry so long and confusing

the only thing i could think of that would make the new tubing better is that it might have mandrel bends...but i think the material is the same...it couldn't make that big a difference so i would just keep the stock tube and a new muffler with tip...thats what i did and i love it

I put aside about 600 bucks for my motor for this weekend, so i was planning on buying some stuff. I guess i am going to look under the hood when i get home tonight and determine how hard it would be to make a home made cold air intake system...shouldn't be too hard. As far as the exhaust, i'm going to just buy a flowmaster muffler, and do the rest myself. Anyone have an opinion on a throttle body spacer?

air raid makes good throttle body system...a flowmaster muffler is a good decision...are you going to put new pipes or just the muffler? are you gonna put a tip on? what series flowmaster muffler are you gonna use? the original 40 series sounds good on the 4.0

My understanding is the stock intake and exhaust are pretty good. I put on a flowmaster 40 more for the sound than any HP gains.
A cheap and somewhat ok alternative to the intake is to pull the snorkle off. It's a no lose cheap mod, if you don't get in the deep water.

I was thinking of a cold air intake as well but I was looking at the volant since it keeps the filter inclosed to protect it from mud and stuff.

I have the banks cat-back and love it. I want to get the polished AEM brute to match my new shiney radiator. I also like the dry flow filter that is very good at collecting even fine dirt that oil filters have trouble with. If you decide to custom the exhaust yourself make sure to make it 2.5 inch all the way.

Save you rmoney on the throttle body spacer and spend on something that'll really work for you! Those things were designed for when the fuel/air mix took place at the throttle body, not for newer fuel injected engines. Great concept, but now it's merely snake oil...

AEM Dry Filter

If the dry filter is better, I might swap out the oiled filter. I have the Mopar CAI and throttle body spacer, which I'm pretty sure is made by AEM.

a cat-back will do nothing for power or mileage. it's a complete waste of money. the only thing you will gain is more noise. if you're ok wasting money on noise, then go for it.

I did some dyno testing and proved that the intake is not worth any hp.
