2005 Jeep Wrangler Flowmaster 40 exhaust

[Honda311418]

If it has a header then it's probably not going to be a 2.5 plus I'm pretty sure newer jeeps came with a 3.8 V6 not the 4.0 inline 6. But yeah what is that one?

Is Your Jeep A 4.0 Or 2.5

where did you get the headers from and how much?

[jkwap91]

I'm getting ready to do this same setup on my '98, I'm just curious though, did your cat have a electrical plug running to it? because mine does and I'm afraid it may mess something up if I take it off.

[aaabball415]

How much extra mpg do you get, if any?

[hrrblharri12]

so you just ripped your cat out and put in a flowmaster 40

Very nice man. Catalytic converters screw everything up. It's amazing what cutting off the cat can do to exhaust sound.

[rangerdanger222]

Sounds good.

[Tedro63]

That sounds wicked bro, nice!!!!! I like!

[c10seth]

I sounds very...beastly!! ^_^

[Sup3rbike92]

which flowmaster is this? i know 40 but which style

[andrewsvids]

o and one more thing... are thoes the torque tube headers or the straight through design

[andrewsvids]

could you tell a difference with the headers and cut off cat? i am thinking about doing that to mine. and i also went the the xdi intake.

[stack0721]

couldn't tell the difference with the cat on or off, but headers really help with exhaust tone.

[andrewsvids]

k cool because i have really been debating weather or not to do it.

[oddball04]

that sounds really nice
