Hopefully people thinking about buying QTP headers will see this and have some sort of idea about what they might be getting into. Some people's fit fine, but after more searching it seems like a LOT of people have this problem with QTPs and the stock motor mounts. You would think if QTP was listening to their customers they'd do something about it

My American Racing headers were close (could barely get my finger through the space) on the driver side. I don't know if it was my motor mounts or what but it rattled a lot and was annoying.
Now I have a UMI k member and poly motor mounts. There is tons of space for any type and size of headers.
I finally started it up tonight and no leaks, no rattles, and no banging. I still have the same clearance that I showed, and no problems yet. I haven't had a really hard launch yet so I can't speak for that, but under normal driving the stock mounts seemed to do the job. This is open header tho, haven't tested the y-pipe yet.

But yea, if I could see how your headers fit compared to mine I think it would be good a pretty good comarison to show how much difference the poly mounts make compared to the rubber stockers.
Do yourself a favor and save a little extra and go ARH or Kooks. Search it on here. QTP's sometimes have leaky collectors too. I had two sets I got rid of because you could see light where the collectors and primary tubes met. Plus my"new" set was dinged all up like they had been put before and returned
WS6 store took them back (great customer service). Granted the first set was off a wreck I don't think that had anything to do with it. After some adjusting I really have no complaints other than the o2 threads. They do take more adjusting to get the headers and y-pipe to fit than I was expecting. I was ticked about the headers not clearing, then after losen every bolt adjusting the header and then tightening down, it seems like I have all the clearance that I need WITH the stock motor mounts. I just wanted to put another thread out there that let people know what it takes for these to fit and that they may not with the stock mounts.
