Just got an O/R H pipe. When I first start taking off (at like 700 rpm) sometimes I hear a metally scraping sound and I can really FEEL the pipe it seems like. It sounds like the pipe scraping the ground. Is this just the resonance amplifying metal sounds from the engine? I mean I know its not physically scraping the ground, its all installed and nice, but thats just what it sounds like. Its metally sounds, then it goes away after I accelerate more and all is good. Thats only in the very low end, like 700-1200 rpm.
And I also have been hearing after the pipe came on under very slight acceleration, something like a grinding, I really have to listen for it though. I dont know if its related. It just seems after the pipe came on I have been hearing all sorts of sounds. Any help?

Never had that problem with mine. Could just need a good old breakin in. . . ? Make sure everything is super tight.
