Comments about Walker EPA Ultra Direct Fit Converter:

bought walker for pipes before. Had no problems so far. Time will tell. Have a good layout for their web site, no problem finding car parts. That is also if they stay that way.
All in all, it is product that i would recommend. Though it would be a nice option to have the pipes stainless steel as well.
It did come with the connecting peace of pipe as well/adapter.

    Comments about Walker EPA Ultra Direct Fit Converter:

    This piece is a direct fit replacement and a straight forward install. For the price I wish the converter came with the gasket and had an expanded end to slip over the old pipe. To install You'll need four 3/8" bolts, washers and nuts to replace the factory ones. In addition you'll need a piece of 2 1/2" exhaust pipe and clamps to join the converter to the old exhaust pipe. Another option would be to expand the converter pipe side so you could slip it over the old exhaust pipe. Install time was about 30 minutes.

    • Direct Fit Flange

    Cons

    • Coupler Needed

    • Replacement

    Comments about Walker EPA Ultra Direct Fit Converter:

    Front bolts right on, back end has to be welded or you must buy coupler and clamps to attach to exhaust pipe. Pipe from back end should be of different diameter from exhaust to slip on over and clamped.

          Best, and most economical solution to replace a CAt Convert on the market, do not use the universal for Pontiac Bonneville models, direct fit is the only one that will work

            2000 Buick Lesabre Custom

            It's stated that this is a direct bolt-on CAT, but how does it connect to the exhaust? If no welding is needed, will it slip on over the piping?
