MBRP 4" Exhaust Cat Delete Option?

[realfstkid]

Hey guys,

I am looking into buying an MBRP Turbo Back 4" Exhaust System for my truck, but I want to be able to put the cat back in if I ever need to in case of emissions, inspection, etc.

Do the Turbo Back kits from MBRP that don't use the stock cat have a pipe that comes out easily to replace with the cat, or do I have to buy a Turbo Back kit that uses the cat, then replace it with a cat delete pipe?

The kits I am looking at are:

S6206P - street legal (use the stock cat)
S6212P - off road (does not use the stock cat)

Furthermore, if I do go with the street legal one, then use the cat delete pipe (FAL414), is this pipe 4" and does it work as well as MBRP's off-road version (S6212P)

Thanks guys

you have to buy the stock cat version and buy the cat test pipe.... something like this: Ford 250/350 6.0 4" Turbo Back (stock cat) EC/CC

What does this mean in terms of performance? Is the Cat test pipe 4". Does this sound/perform the same as the non cat kit?

I believe the cat test pipe to be 4". I hope this picture helps answer your question. Pictured is MBRP P/N FS9414 stainless cat test pipe installed on MBRP P/N S6206304 turbo back 4" street legal kit. This is the way to go if you plan on re-installing your original cat at a later date for inspection purposes.



Way easier than trying to install the factory cat on an off-road system. Off road systems, as I understand it, have solid piping and no provision whatsoever for the cat.

I have had this setup for about a year with no problems. I have had inspected twice without the CAT and no issues in Texas. The only problem I had was the bolt heads they provided hit the flange weld on the delete pipe. A quick trip to the hardware store for a new SS bolt and problem solved.

Thanks for the answers guys. I went ahead and bought the Installer Series (Aluminized Steel) Turbo-Back (Street Legal) and the Aluminized Steel Cat Delete Pipe from Xtreme Diesel Performance for $390 shipped after their 10% 4th of July Sale. Figure it was a good price, and since I have the turbo out of my truck until next week (repairing HPOP, and doing an EGT Delete) I thought it would be a good time to add this.
