Don't let the steering shaft scratch off the Swain coating. Later on the coating will peel off .

Friday it goes back in to have the bolts retorqued. We'll look into it then.
Thanks to everyone for all the pointers and advice.

So... After some time has passed, how do you like the OBX headers and exhaust? Have you had a chance to go back to the dyno from your baseline 311rwhp? I hope to see you and your car at Carlisle this year. I am leaning towards the OBX exhaust, but still have that old LT4 resonator hanging around.

Bert, still happy with the OBX. One hitch was the Stage 8 header bolts, we couldn't get the locks on, like the jesus clip was too thick.

'fraid I won't be at Carlisle.

Haven't had the chance to redyno, hopefully soon. Since the first dyno I've done headers, removed the cats, actually replaced them with 6" glass packs that look like cats from the outside, did the exhaust and installed a Marc chip. -Steve

Sounds good... Me so jealous. I'm going to order the OBX exhaust tonight. My Z Dynoed at 321 rwhp with just Haibeck chip and open air cleaner. I hope to come close to 340 rwhp w/ OBX, however unlikely. Share your dyno when run with headers and exh and I'll share re dyno just for exhaust.

Bert, did you dyno before the chip? Marc advertises ten hp. Because I had no cats he tweeked my program a little tighter. - Steve

No, the chip was installed before the dyno.
