Hello,
I was wondering. I am having my car dyno tuned next week and I am also having my headers ground down a tad so that I can more easily access the sparkplugs (currently with my World Product Heads I have to loosen the headers to remove the sparkplugs) My question is this. The speed shop that is doing the work noticed that with the headers bolted to the engine, and the sidepipes bolted hard to the frame, there should be little or no give at all. They are concerned that as the engine torques there is not enough give in the header/sidepipes. They said that this will constantly loosen the header bolts at the least, and crack the headers or collectors at the worst. They suggested a high temp rubber bushing in between the sidepipe mounts and the frame.
Is this really a problem? Has anyone else dealt with this? If so, what did you do to rectify the situation. Any help would be greatly appreciated.
Thanks
Scott
