First things first the track pipe and stock mid pipe equal disaster. Second the tick is a leak I ran my UEL tick free. You may not see the leak but it exists could be a warped flange or bad gasket. If you are going to go UEL you gotta do it all header back and wrap it at that the stock is wrapped with fiberglass to deaden any other engine sounds coming thru the exhaust.
Next: you sold your stockers? I've bought 2 of the only 3 I've ever seen for sale I nodded one and sold the other Rallisportracing.com
there is one more for sale I can track him down and give him your info it's in OH.
