Kooks headers install
I recently had my shop install a set of Kooks LTH 1 7/8 in with high flow cats /x pipe on a 2102 GT. The steering column seems to be touching the headers on the drivers side causing quite a bit of vibration especially at high RPM. With turning as well I can feel some friction. Has anyone else had this problem ? Is it some thing that I'll have to live with or is there a resolution ? Thank you

No way you live with that. Something's going on. Either look at the motor mounts or the header install. It's so fricking tight down there it ain't gonna take much to touch. Even if you have to clearance the header a tetch with old Mr. Ballpeen that's better than living with what you are describing.

Just curious what you paid for the install? I was just quoted $650 for kooks LTH and x-pipe.

+1 something is wrong. There is not a lot of clearance, but there should not be any contact whatsoever. Remember your headers are going to be EXTREMELY hot. Air is a good insulator. Metal to metal contact at those temps could lead to failure in a very bad way. No way the shop should have let you drive away like that. That is just absurd.

1 7/8 is a big tube and I'm not convinced a tube that size is necessary unless you're doing hardcore racing. Troubleshoot for the cause of contact. If you can't find it then dimple the tube for clearance. No, it will not have any effect on power.

There was a test somewhere on the internet where they beat the headers quite a lot and dyno tested and showed very little effect on HP.

if its hitting, please dont take a hammer to your brand new headers, place a washer or two under the motor mount to gain the clearance you need, besides its easier than the redneck hammer method as well.......

A picture of where the interference is occurring would be helpful.
And denting it should not affect performance based on the testing video I watched on this forum. However, not sure how you would put a dent in it without uncoupling and steering linkage first.
