Man, you're lucky. Mine still hits on the steering shaft if I take a right turn hard (on the track, on-ramp, etc). Looks like I'm going to have to pull the header out and increase clearance. Not really looking forward to that.

If you have less than 1/8" of clearance around the steering shaft, pull it now and add a dent for clearance. The steering shaft isn't perfectly round, and when you turn to the right, the shaft is slightly wider, reducing clearance even further.

I've tried adding clearance with the header installed, and it just won't work, the angle isn't right. Trust me, do it before you get it all wrapped up.

Almost finished. I got the headers in position, but it is HOT here in Alabama!. I had to splice two wires on a sensor located on the oil pan. Heat had made the wires brittle. I replaced the wires and covered them in heat wrap. The starter was a monster. BTW what are the torque specs for the starter and headers. I used studs instead of header bolts. It made the mounting easier. I can't wait to hear it fire up!

The torque is 37 ft lbs for the starter, start with 11 ft-lbs final pass 18ft lbs on the header bolts.

I had to put a dent in mine. I had less than 10thousands clearance between my header and steering shaft.

Worst case? I suppose it could damage the steering rack over time. When you turn right, the engine leans to the left slightly (there's SOME play in the mounts) and depending on clearance, the weight of the engine rests on the shaft. That'll put the engine weight's pressure on the u-joint and ultimately the rack. There probably won't be any immediate impacts, but it's something that could have more long-term issues.

Immediately, you do feel it through the steering wheel. It's annoying. When I turn hard right (even just an on-ramp or something), there's a very significant vibration through the steering wheel. I did have my car at the track and put an hour's total time on it there with no ill effects other than vibration through the wheel on right turns.

I just regret not making the dent deeper than I did since I'm going to have to pull the header off. I got it sealed just right currently with no leaks, and I don't know if I'll be able to do it again. That's why I caution: if you have less than 1/8 to 1/4 of an inch clearance, you'll regret not adding some. I know it's hard when you're excited to get them on (that why I rushed mine) but trust me, it's worth the time up front.

Oh, I hear ya! My car's done and dyno tuned even with no leaks. I really don't want to touch it, but I track my car and really don't want to risk hurting anything.

I had to clearance mine after I had them ceramic coated. So just imagine how pissed I was. Especially when I waited for the revisions to solve that issue and still had to clearance the header. But all said and done they sound great and you definitely feel the difference even without tuning. Good luck and enjoy

I'd be really interested to see what you're able to cook up if you try. I tried on mine by wedging a piece of wood between the steering shaft and the frame rail, the heating the header and banging in on it with a bar. The angle just wouldn't work out right, but there's probably a way to do it.

I still love mine. For the price, the sound and performance is incredible. It doesn't need a ton of added clearance, just a little more than I gave it. I've read of guys with the much more expensive headers needing to do the same. I'd be REALLY pissed then.
