JBA Exhaust

I have a question about matching the Jba Axle back system with one of their h-pipes. I want to know what i am going to have to do put both systems on at the same time (i dont want to pay for installation and my friends have a garage) because i know that the axle back system is not going to meet the h-pipe. Am i going to have to cut the existing pipes and re-use some of the sections between the two parts in order for the systems to fit? Also the h-pipes say they are for long tube headers, so will they fit with my stock manifolds? Will i fail emitions with the cats on the JBA H pipe (it says they are off-road) but i have heard they can pass.

If you can answer any of these questions that would be great
 
I don't think the JBA H-pipe will work with the stock headers - I bought mine along with the long tubes. The axle-back should fit fine (it only replaces the mufflers), but not the H-pipe. Also, even the catted H-pipe comes without O2 sensor bungs, so you'll have to use a tuner or O2 simulators to avoid the dreaded check engine light. I would (and will) keep the stock exhaust parts for 2011 when smog time comes or if the car is sold after 2008.
