I'm not sure if you can get a catback with no muffler, but it's worth a shot. You should give them a call. The piping kits are unwelded pipes.

 

Piping kits come with flanges and hangers, you just have to get your muffler welded on.

 

When i emailed VRS they said for 60$ more you can get them to weld up the tubing kit for you to be bolt on minus welding on a muffler. or in this case replace the rear section with the nismo/borla one


BTW: This wasnt even a week ago when i emailed them.
