I went to install my RacingBeat pre-silenecer today on my 88TII. I removed the cat, and was dismayed to see that the presilencer was too long to fit in the space. I believe the previous owner had installed the Bonez superflow downpipe and hgh-flow cat combination, and that the Bonez cat is smaller then stock, and the pipe between the downpipe and cat is longer then stock (I believe it's supposed to be a presilencer, but it looks pretty chinsy to me)

I plan to buy the the racing beat downpipe, which should fit jsut fine between the turbo and presilencer once it's bolted on to the cat-back. I just wanted to make sure that I had my problem figured out before I went about fixing it.
