Hmm, I had taken off the cat on my 1982 320i years ago and found the loudness increased quit-a-bit. Thinking the same would be the case in decating the Exige, I was expecting a difference. I can hardly tell any difference. Although, I think maybe it is a LITTLE louder(?) between 7 to 8K RPM. I suppose the way they were made back in the 80's is a lot different than in mid-2000.
Jim said it would be louder with the decat. Wouldn't think it would be that much louder, but we'll see. It it's too loud, I'll go back to the cat pipe.
