on what i would need to do in order to delete my cat ? I have a magna flow cat back system, any of my muffler shops around town here dont carry 4" pipes ? And with the current exaust i have on now, what would i need to do to make it a turbo back/ no cat system without purchasing a whole new system? And I were to bite the bullet, what would be a "true" turbo back/ no cat system? I have read that some of these manufactures claim to be a turbo back system but is really not a true turbo back.. Explain please..thanks in advance

I would think that you should be able to get the cat delete pipe and front pipe from magna flow to complete the system you have. Plenty of the vendors here sell magna flow,contact them. As far as "true" turbo back. You're probably referring to the down pipe from the eng to the exhaust front pipe.Some kits have it some don't.I've never changed one but looks like it could be "fun" to swap out.

MBRP makes a nice cat delete pipe that fits in the stock location and can be easily removed to replace the factory cat pipe for emissions testing or warranty work. Here's one for an LLY http://www.alligatorperformance.com/product_info.php?products_id=2511
Let me know if I can help.
