    Looks like nice work. Did you keep the stock headders? If so did they replace the gasket? I had a reoccuring leak after new exhaust was put on my 95 even with new gaskets. Every month or so I had to tighten up one bolt.

    Thumbs up

    Has a nice sound and looks like a real clean installation. Let us know if it helps your mileage, after a week or so.

    That sounds beastly! Very nice! How does it sound at freeway speeds? Loud hum or comfortable?

    I had a Sports car several years ago that I had installed a Flowmaster in. I couldn't stand it on long trips. Lets not forget to mention my wife hated how loud it was.

    Ok, so it increased my mileage about 1.5 miles to the gallon over the full magnaflow system I had, the stock manifolds are still on it for now, but he knew about that bolt and actually told me about that, checked it for me, it is the drivers side rear bolt, that one is the only one that has problems, and I love the sound, it is just a nice little rumble at 2000rpm going 75 on the freeway, not an annoying drone, just a nice rumble. It obviously is much different in person, but just wanted to give everyone an idea of what it was like. thanks for all the positive feedback, when I had them installed, we talked about muffler choice, and glasspacks are the only ones that are about as loud, but I didnt want the "crackle" im sure everyone knows what I am talking about, so this muffler turned out really good. He also bends all his own pipe, so none of it is spliced anywhere, all pipe and just the seems for the muffler, he does a realy nice job. Thanks guys.
