Back in my day the two TX beers were Pearl and Lone Star.. we quit drinking Lone Star when they sold out to yankee's.. Shiner was what you drank when you couldn't afford anything else.. I can't get Pearl out here..

I think I'll need to borrow $50 from you in order to send it to Positron ;D

He already quoted his price of cold beer at AF2!!

I think you should paypal the $50 to Positron that you were going to spend on a new tensioner

per positron's advice I torqued the header bolts to 45 ft/lb's the knocking sound is completely gone now, phew that was the cheapest fix to a problem I caused myself YAY!

OK so it didn't blow the tissue around but I thought maybe I just didn't torque down the header enough......torqued the header bolts a little more and here's the result

it's a marked improvement therefore I think Positron nailed it on the head with the problem.....I felt it seemed strange that this would occur right around my "reinstallation" of the exhaust.

So now to look at the thread with the brammo torques and go use my torque wrench to check them as soon as the header cools down a little more.

Originally they weren't torqued down very tight I guess....it's my tendency not to force things and I guess I should have looked for the torque requirements first.
