pretty much gonna leave it close to stock, i have truck headers that i cut the weird flanges off and welded 3 bolt flanges to. i dont have room for the factory y out of a truck. thats the drawback of a jeep.

my biggest question is: can i tune the motor to work good with this exhaust setup? or do i need more back pressure before i tune it?

 

what brand headers are they? imo i think the way it is now is killin ya,and the tune.have you checked out any jeep forums to see what other guys with lsx swaps are runnin?

 

summit brand headers. some run a y but it always results in an actual T in the exhaust, not what i would call good for flow.

 

Anything on your set up yet? I still say you should run one muffler. Your gonna have to find a way to get the Y pipe in there, even if it's a short one or have the pipes welded into one. Any pics of the under the jeep yet?

 

i talked to a local tuner that i might have tune my 5.3, he seems to think that the exhaust will be fine. i dont know if this makes me ok with the exhaust or not ok with the tuner. ill get picks tomorrow. the only way to get a y pipe is to make my own headers. i would rather not do that, its going to be a pain in the A$$

 

yo could get a set of mid length headers,you'll keep more down low that way to.

 

install a H pipe and call the exhaust done. the low end torque loss is most likely due to something else unless its just crimped shut in some places.

how hard was the 5.3 swap? i'm looking to do a HEMI swap on our little wrangler project.

 

tx, I was goign to do that in my 01 ram (the hemi swap), and was told many times that the 5.9 is torquier, but if I had to put a hemi in it, make it the 6.1 because the off-idle torque of the 6.1 is impressive, vs the 5.7's.

just what i was told.

 

the 5.3 was easy to put in the jeep, the only part that makes it difficult is the exhaust. i considered the hemi, but cost kept me from it. those motors are so damn expensive, and i can bolt in a ls7 if i need the ultimate in power, or 6.2 caddy. the flexability of the lsx series motors is imo unbeatable. i kinda wish i would have put a NV4500 in it instead of the 4L60E. but whats done is done.
