If you have the skills and resources to do that type of work, go for it! If not I think you'll find out that it'll be a costly venture and other IC's (like the CAS V4) start to look worthwhile.
I guess what I'm saying is that you gotta draw the line somewhere. I drew the line with the removal of the top four rows and having the end tanks welded. I didn't want to put any more time and money into it. I just didn't think it was worth it.
$325, removing pieces from the car, test fitting, cutting, more test fitting and about 20+ hours labor?
vs.
$600, bolt in product, and 2 hours?
Only you can answer that one. It's different for everyone I guess. You'll definately have a good winter project on your hands. Have fun!
