well i brought my TJ over to my buddies today (along with some pizza lol) to get some help changing my header and downpipe (PO welded the header to the downpipe) i went with the cheaper one that comes highly recommended by other forum members, the one with the expansion joints to keep it from cracking, looks like a really nice quality header considering its from autozone, well we got the intake manifold off and whadya' know i have had a borla header lol! so for anyone considering spending the extra money on one.. dont! i bought my TJ in dec. and it didnt have an exhaust leak at all, and it was so cracked that in 1 spot there was only .25" that wasnt cracked, in total i counted 5 cracks on it, took a short video of them just to show it, anyways all in all it was a nice easy swap took us 4 hours on the dot, and i spent 1 hour cleaning the intake / throttle body, and intake ports on the head with TB cleaner (intake valves were nice and clean so i left them alone) being that it is sunday and neither me and him can weld i got to drive it home on just the header + downpipe lol.. it sounds AWSOME lol if i didnt work third shift i would SOO leave it like this lol!! but im going to the muffler shop to have it welded to the cat in the morning, i do have a flowmaster 40 series which sounds nice, and will sound even better with a nice non-leaky header
anyway heres some videos of the borla with cracks, first start-up and running on the highway lol
heres the borla, 1 of the cracks (its obvious which) is from me cutting around it to get it out
heres the first start-up, running a little rough at first due to the bottle and a half of TB cleaner i used
but this is just open header w/o the downpipe, and also no O2 sensors lol
here it is with the header + downpipe, still no 02 sensor tho, didnt bother to cut the rest of the pipe out, going to let the shop worry about it lol, so we safty-wired it out of the way i LOVE the sound like this lol!!!
heres second + third OMW home, sorry for the bad camera action lol tryin to shift
and here it is on the highway, when it "sputters" thats me playing with the gas lol
