Hooker longtubes on LS6 Crate Engine HELP!!!
Hooker longtubes on LS6 Crate Engine HELP!!! I have a 98 WS6 Convertible with an LS6 crate engine, I decided to put some Hooker Ceramic Long tubes Part # 2469-HKR on after about 10k miles...THESE THINGS DON'T LINE UP AND HIT THE FRAME ON BOTH SIDES! On the passenger side the back of the header header hits a round piece on the head! 
I thought the LS6 and LS1 were exactly the same dimensionally...I've had 02 exhaust manifolds on the car and they fir perfect so what do I have to do shave the frame?

I read some threads on the Hookers and I didn't hear of any major fitment problems like this...this is not worth the hassle. I got a good deal on these $380 from Summit(they matched Amazon.com's price} which is why I got them...plus I have a Hooker cat back.

You really only have 2 options. Grind the area on the k-member, or take them off and send them back. I got a set of chrome bbk headers a few weeks ago. If I tried telling you how easy these headers went in, I wouldn't even be touching the tip of the iceberg. SUPER EASY. The are the nicest tucking headers I have ever seen. Their y-pipe merge is outstanding, and I also got my bbk headers from summit. So you could return them and get the set I have which includes a y-pipe for the same price you paid for just headers.

I went with the Hookers because they were ceramic coated...those BBK's aren't but If I had to do it again I would have got those. It looks like I'm going to take them off and grind the k-frame tomorrow and hope that works.

^I'll be doing the ls6 swap on my car this summer 112 to a 122 trap is a huge jump ith just that change. did you add nitrous or any other mods at that time? Only difference is my ls6 is gonna have an auto behind it.
I have Hooker long tubes and poly mounts and have no issues with fitment at all, something is wrong.
Oh and it has nothing to do with it being a LS6, either something is up with the motor mounts or those headers aren't made right...
Sorry to hear about that issue, cutting off a little bit of the K member will be easy and it wont hurt anything.
