Adding a Downpipe & Delete Pipe to Cat Back Exhaust
I have been doing a lot of reading on the forums, and quickly discovered that everyone recommends doing a Turbo Back system over Cat Back. I recently purchased a Cat Back Banks Monster Duals system for my 05 F350. I have not installed it yet and would like to add a 4" downpipe and cat delete pipe to the system.
My question is:
Are there 2 different types of cat delete pipes? One that would be used on a true 4" system from TB to tip. The other being one that would be a bit longer that would work with a 4" cat back system? The reason I ask this is that the rear intermediate pipe is only 3.5" on the cat side, I'm assuming you would chop this off at the point where it is full 4" and then use a longer cat delete pipe that would extend to this point?
I hope this is not confusing, but from what I've gathered I would want a 4" from turbo back to tip, so I'm thinking I will have to get rid of the 3.5" portion of the cat back exhaust that was supposed to connect to the back of the cat.
Any help will be much appreciated!
