RE: cat back questions
Spray silicone and a craftsman cotter key puller and large screw driver if you do not have a pry bar set. If you do have pry bars, the medium size one works fine. Not that hard to gey the old muffler out.
As to a header for the I5: RE: H3 Headers
IMO: you are spending a lot of cash and effort for a nominal gain at best. Have you ever looked at the I5 exhaust manifold??? I thought not.
Let's take a look. Cast, but runners that flow close to what separated tubes can do for you.
Showing the manifold CAT as well. #3 is the heat shield that some people have hadget tad loose and make a racket. I am very confident you would not be able to "feel" the difference, andthe dyno measure would be small. Might sould cool though.
Rich, you will like the MagnaFlows, I think they did a good job, welds and material are good, clamps are HD, makes for a easy bolt on.

RE: cat back questions
jackk frost, No, I don't have a header for our H3 (yet). The Cat gutting article I found yielded 10 hp gain, so I would think the Header would yield the same +/- 2 hp.
Once I get back I am going to get the Bassani because I had exhaust from them before.
Plus if I need to change the muffler out to make it quieter/louder, it is a standard type.

Someone please correct me if I'm wrong on this, but I've been told that there really isn't much of a need to replace the headers anymore for the gains that you will get. The factory is building them better than they used so that there isn't THAT much of a difference anymore.
