I bought and replaced a few $300+ headers. The last one I bought was the OEM replacement with the integrated flex pipe. Cheapest and best so far!!!

Ticking noise upon acceleration or going up hill.
I've had gaskets, cracked manifold replaced, new bolt kit to be installed with new manifold, why do these crack?

BUY AFTERMARKET STAINLESS STEEL VERSION, OEM IS THE SAME AS THE OLD ONE!
I have been dealing with problem for a while, I thought it was low oil or a lifter issue, it wasnt until I was on a forum that I figured it out along with the symptoms. The knocking on start up, quieting down once heated, bad gas mileage, drivability no what it use to be, it seems like the muffler or exhaust was louder in some way. I beleive this also lead to my throttle sensor issues, which inturn on highway speeds, engine would actually mis. Having issues fixed soon will update.
