Petevette, you will like the 7 port very much with that pipe. what are you running it in, you can get close to the same feel on the bottom when clutched correctly, and it has a crapload of top, the stock 7 port is smooth, so maybe a little more aggressive on the clutch and you will be very happy, or another pipe, i like the 1005 on my 7 ports, plenty of bottom without killing the top end. a pipe i havn't tried yet is the 2045, i hear it is working very well on the 7 ports, and GO is making their own 2045 version.
