Installation Time: Full Day

Worth every penny! Here are some install tips..
Let me start off by saying I could not be happier with this H pipe. It looks beautiful, it fits perfect and it sounds amazing. I always liked the rumble of an H pipe over an X pipe, and this does not disappoint. I only had a set of GT500 mufflers, and this system unleased the beast in my mustang. What I like most about it, is I am not looking for an exhaust that wakes up the neighbors, but I want something that lets people know that a mustang is coming, and that's exactly what this does. With that in mind I have some tips: First, I called several shops, both chains and small shops, and I couldn't find any that would delete the cats for me. They all are worried about the EPA, so if you buy this, plan on installing it yourself. Second, as mentioned in the install instructions, make sure you have some penetrating oil, and make sure it is stronger than WD-40. I tried that first and ended up going and getting some liquid wrench because those rusted bolts would not budge otherwise. Even with the liquid wrench, plan on working to get those bolts loosened. I had a 1/2 inch socket wrench with about 30 inches of extensions on it, and that took every ounce of strength I had to break those suckers loose from the top. Then breaking the other two loose from the bottom, I used a crescent wrench, and hooked another one on to use as a breaker bar. I found that worked quite well. Third, having the right tools can make things go a lot faster. You will need a 15mm socket for the stock bolts going from the down pipes to the exhaust manifold, as well as for the clamps going from the stock H pipe to the mid pipes. You will also need a 13mm socket for the clamps going from the down pipes to the H pipe. When you switch over to the Pypes set up, the conecting bolts from the exhaust manifold are going to be a 9/16 size, and make sure you have a wrench too so that you can hold one side of the bolts while you tighten the nuts. And finally, when you are installing the new pipes, use a floor jack and a piece of wood to lift up your mid pipes that are hanging down. It is dang difficult to try and hold everything level, while tightening it down. I tried it the first time without doing that and ended up with exhaust leaks out of every break in the pipes because the whole system was sagging. The next day I loosened everything, and when I lifted up the mid pipes I could just see everything line up and fit better. I apologize for rambling on, but I made a fair amount of mistakes that led to this being a much longer process than necessary. Hopefully this helps you avoid some of the same ones I made.
