Hey guys i just bought a set of tork-stepped Hedman Longtube Headers. Has anyone ever used these or know any one with them? Also, i called Hedman but the couldnt answer my question...What type of H-Pipe will fit these headers? I would think any brand would be able to bolt right up but im not for sure. OR I have also read that i can just modify my stock midpipe by relocating the cats. Is this true? and will this restrict the performance gains of the Longtubes?
