Default header hitting k-member

Have any of you guys ever had a problem with Jet Hot LTs or any header hitting the K-member? Ever since i put these LTs in, one of the primaries hits the K-member.

Ive read that some people have problems with LTs hitting the excess thin metal on the K member that can be cut off. But mine is hitting the whole K member and its annoying when it rattles/rubs when i drive.

Sounds like your motor mounts have seen better days...

Oh, well there goes my theory. Time for some LPP's maybe.

mine does the same thing. I have hooker headers and it hits on my driver side. It really sucks since i had mine jethot coated like yours and it has rubbed it off there now. The only option that i have found is getting a tubular k-member

My LPPs hit the k-member on the PS so we notched it out, I will buy a tubular K-member to truly fix it soon

Same problem here. LPP's are hitting the k member. Gonna take a grinder with a cutout wheel to it tonight and solve the problem until a BMR Tubular unit can find its way underneath it.

Yea notching it out seems like the only valid way to fix it unless you get a tubular k member. Will notching it out weaken the stock k member at all?

NA. Im not worried about it, seem this is a problem with all brands hit or miss. Cool part is its cheaper for a K-member than new headers and an excuse to buy one!

Yup...I am currently in the process of fitting my Ebay, LPP copy LTs and it hit in a bunch of spots: I had to remove the remote oil cooler on the oil filter, cut out not only the thin metal ledge, but also a round spot in the K-member in 2 spots for two of the tubes to clear the frame. It's not a lot, but just enough to make installation drag on into today when I was anticipating them being done yesterday. I was actually just about to ask if this was a common problem or if I had a defect in the set I bought/geometry was off or something. Obviously it has arose before :-(

Nope it seems not so easy for someone to make a quality product.

My LPP's cleared the K-Member just fine. Seemed like some of you guys had to really do some modifications to get them to fit. Guess other then having to remove the oil cooler I got lucky. To the OP, you will have to grind it down a bit it sounds like.

my jet hots hit on the pass. side. had to notch it. it will not hurt the frame. just cut to lines and hammer the middle into the kmember. done. then install the header. the factory Kmember is exremely strong. dont even worry bout it.
Ive installed quite a few sets of headers, and there all a bit diff. from car to car, header to header. (Im talking same name brand header to header). matter of fact, I could get you a pic of mine since the eng/Kmember is still out of the car in the garage.
