just when i thought i had fixed it all.... ok so i get my headers installed, rebolt the ypipe after messing with it for several hours, check it to see if it knocks, it doesnt, so i take it to the shop to have it wielded. so im driving down the street and it still doesnt knock, except only when i slowly roll out of first gear at low rpms, as if im gonna stall..AHHH...i checked it by putting the E brake on and putting it in first gear and letting the rpms drop real low and it doesnt knock. i even give it some gas and it still doesnt knock. only when i drive, and its only in first gear that it does this. also the knock is more up front, sounds like its coming from right underneath the pedals...any suggestions??

Two things to try first,if its hitting the K member you will see visual evidence where it is coming in contact, either grind the K member there or use a prybar to pry the header over slightly to gain some clearence ,may have to do a combination of both,what type of LT's are they?

If it is hitting somewhere else like on the y pipe or later you might be able to get away with wedging a thick heat resistant peice of rubber inbetween the pipes and wherever it is hitting. This worked on my true duals, I got the rubber peices from a muffler shop for free. You just have to figure out where it is hitting. Due to the heat though I dont think I would try wedging rubber in where it is touching right on the header cause it probably will melt. Good luck finding where it is hitting.

Mine is touching the K Member and the Y Pipe is banging as well. Does this cause false knock and therefore a reduction in power from knock retard?
I am getting about 4* of KR at 4400 RPM.

I have the Pacesetters also and mine don't come close to the K member, I did have to adjust the y pipe because it did rub the SLP SFC's, no longer an issue. I am sure the KR could be caused by the contact.

alright i fixed it. it was the K member..had a nice ding in it. but i have one other "inconvienence." i think my heat shield on the right side is rattling. i tightened up the screws but it didnt seem to help. is there anything i can do to fix this or should i just go ahead and take it off? is that even a good idea?
