I have a 90gt with mac 1-3/4 in long tubes. Has anyone had issues with them hitting the frame rails in the engine compartment? It has brand new energy suspension motor mounts. The heads have raised exhaust ports, but thought all aftermarket head were raised alittle. Just wondering, it causes alittle vibration, i can live with it.:)
