Mr Greg H. This guy was rude and did not give me what I asked for. I asked for 2 1/2 and he put 2 1/4 on. He made header collectors out of strait pipe and flimsy flanges out of tin foil. They leaked of course so I went back to complain and he just shoved an additional gasket in....I paid extra for a cross member cut out and he welded out a piece and flipped it over leaving weld drips and slag all over. The rear tail pipes were so out of shape that water dripped into them and froze and the car wouldn't start. Told me he could not do mandrel...he didn't have the bending equipment. Both pipes going over the axle were different. one was rounded and one was squared off. He put my car down and told me that he was use to working on much better cars. The only good point is that they didn't fall off. Wonder how he is still in business after all these years. Stay away from this H... Don't believe me I have pictures and a receipt.
