But you can buy the full catback exhaust which includes the b-pipe and axleback exhaust.

I've already got comptech axleback exhausts. Can I just get the B-pipe instead of getting the whole catback system that includes comptech axleback exhaust?

Yes you can.

for those who have the b-pipe or know...what is the size difference compared to stock?

If you go to www.comptechusa.com it tells you the size under the product info. I believe it is 2.5in. Has anyone toyed with the idea of installing a Bpipe with stock exhaust and headers? think it would do anything? I like the stock exhaust note of my 03 I don't really want the drone of CT exhaust .. think the bpipe would show any gains with stock mufflers?

yeah thats what i was planning to do. Thats why i was asking how much bigger is the bpipe compared to the stock pipe

wow...... I'm so excited with this B-Pipe
