exhaust and intake

i have been thinking of putting a exhaust and a intake on my jeep. i wanted to use the banks cat-back and banks air intake. i was just wandering what kind of performance i will see and if it will make my gas mileage better. I have a 04 unlimited automatic with 33" tires, 4.88 gears, and front and rear lockers. thanks for your input

you will get a little more power and gain a few gas millage.

i got my intake from ebay. it has a heat shield to help keep the heat of the engine away from the filter. it was about $80 shipped

I am looking for more power out of it than mpg. Between 1500 and 2500 rpms the jeep bogs down. So i was hoping a little more power will help that out. Thanks for all your helpful input

you really don't get too much power from intake and exhaust upgrades on a wrangler.

the banks exhaust i have raised the exhaust pipe to a 2.5" from the factory 2.25". it still doesn't add much power, you can tell the difference but its not much.

jma ur chrome intake.. does that get really hott? cuz most intakes arent chrome or metal because they are supposed to stay cool and resist heat so the air doesnt warm up

I put the Banks Cat Back exhaust on my 2000 tj and I am very happy with it. I could tell a slight difference in power when 1st installed. I think I have just got use to it now. The noise is awesome! Real deap.. Highly recomend exhaust. As far as intake I think just any el-cheapo off ebay will work. I cant justify spending $300 for a intake when you can get one with same quality and performance for $50. If it doesnt come with a heat sheild I will fab one up.

it doesn't get too hot, the heat shield keeps the air flowing a bit cooler than stock. it gave me great throttle response and some more power along with gas millage. 3rd gear has a good deal of power. once i get to 2,250 rpm in 3rd it just takes off.

Guys, I did a ton of research on this exact subject and ended up with the Banks Cat-back (w/ 2.5" outlet) and the AEM brute force w/ throttle body spacer.. Here is the skinny: you really do not feel anything different until you get into the upper RPM range.. All you can hear is that sweet tone of the Banks and the sucking of the AEM at 2500rpm and below... But, when you really get into it you can most definitely feel the different. Jury is still out on the better MPG though..

I was just thinking, why not make my own snorkle out of PVC and a washable air filter like a K&N at the top. Anyone ever tried this?

So what about just buying a K&N Cone air filter with a small chrome tube that would then connect to the air cleaner? b/c u have the new air filter, youre gonna get better air flow into the TB despite still flowing through the stock air cleaner body rather than a straight pipe? With the stock air cleaner piping, you might not be getting a wider pipe flow, but its not getting warmer like the chrome could. i saw this on ebay...

1997-1999 2000 2001-2006 Jeep Wrangler Air Intake S+K&N:eBay Motors (item 370219403149 end time Jul-23-09 03:03:43 PDT)

figured for the price i'd make an offer and it wouldnt be a bad mod.

1) the difference a filter makes in minimal
2) the small "chrome" tube is pointless because it doesn't eliminate the bends and flex areas of the stock tubing which are very restrictive
3)most intakes use aluminum not chrome because of the heat factor, the aluminum works better at dissipating heat

jl, i appreciate the answers a lot. and with thorough thought, decided that for the heck of it, for $50, i just bought one of those "ChromeIntakes" off of ebay. apparently, the system includes the cone filter with a 3" T-306 aluminized heat resistant tube that connects with the TB. I figure for $50, and 45mins of labor, i'd try it out and see where it takes me. I've got the new magnaflow muffler installation tomorrow morning, and then the intake should be in later this week. enough time for me to see any performance changes.....if any!
