Its doable and clean and not detectable if the welds are done up again properly...

or...you can just be a G and gut the resonators and 2nd cats...

Well the resonators are gone already .. I just want a little more sound and some power .. I plan on just replacing it with straight pipe instead

I did, it sounded good and is inexpensive

So did I. The sound is just right for me. I sold my Akra Evo and am happy with the secondary gut.

Does anybody make a kit with the secondary cat delete? I would be more inclined to go this route and not have to buy a tune to prevent a CEL. I would think the dealer would be a little more lenient with this rather than a full catless system. I've been talking to the dealer about the full Dinan race system, and they said I would be pretty much on my own with regards to warranty issues. I really do not want to throw away the warranty on a brand new car.

Why bother, looks like you don't keep cars long enough to justify the expense.
Thats a dream line up you have torn through there....

One of my neighbors asked me if I was a writer for a car magazine. I just laughed.

Plenty of options out there to eliminate the secondary cats. Fabspeed, Innotech, Challenge, etc..

How much should I be paying for secondary cat delete

Total waste of time IMO. Ditch the primary cats as thats where the hidden power is. If you dont want a tune just plug in the Akra Delete-R. And why did you take out the resonators? Are you trying to make it sound raspy?
