[HI Cobra]

MaSnake,
Now that you have seen how much it is restricted it is easy to see why it
can't breath. I was lucky (I guess) with the new pipes because there were
no problems at all with the exchange, and what a great surprise with the
power gain. I am hoping yours are as easy to change as mine were.
You will be happy. I thought the old pipes sounded fine but got a big thumbs
up from everyone regarding the sound of the new ones - much better.
