I wanna run the ebay OBX LT header setup, (2) 14" magnaflow muflers, (2) high flow cats and (1) X pipe all with 2.5" piping. I have 2 questions. Will I need anything else for a complete working exhaust system? (I am installing with a buddy) Also what O2 sensors do I need and where should I place them to avoid errors in my dash.

Is anyone running something similar to this, any tips/complaints?

Thanks for your help in advance.

 

I had 2 14" maggies and tue dual with x pipe all 2.5" and the sound was great. I then put on OBX long tubes with no cats and it was way to loud. Highflows should keep the noise level down but you may want to go longer mufflers. I then tried a dual in dual out 18" with no cats still and way to loud while just crusing down the road or freeway. I now have a saleen set up that is not much louder then stock but with no cats and long tubes its perfect.

With your set up I would recommend a 18" dual in dual out maggie with internal xpipe. I think it would be about perfect. On the 02 sensors I had to extend the rear 2 only I believe. I just did it with wire but some people actually buy adapters to extend them

 

go true dual magnapacks (14" round bodies). amazing sounding. and with LTs and HFCs. wow.

Add a blower and they all sound good.

 

I already have the 14" rounds, I hope it will not be too loud. My buddy has a 6.0 GTO with straight pipes on it, and its by far the loudest I have ever heard. But I can stand it because it sounds like a bat out of hell with 400HP As long as it sounds good I'm not worried how loud it is I don't think...(TBD)

What are some of the O2 adapters I have to choose from?

my 08 fx4 needed two sets of the extensions

all four worked perfect. might suggest putting in the o2 extensions while you have access to the headers

if i were to do it again, id get the 22" muffler. my 18 just isnt quiet enough sad to say

 

Is there a seller distributing this all as a kit? Or are you piecing it together and buying the products from eBay?

 

I have an 06 with a 6.5ft bed so I may need extensions. I was gonna get an exhaust shop to do from the headers back and then have my engine guy do the headers.

Wouldn't there be a HP/Torque loss with a 22" v the 14"? (Maybe I won't notice it after the LT Headers)

The more I talk with people, the more scared I am it is gonna sounds like 1,000 bats out of hell and that may get annoying after a while.

Anyone wanna trade 22" maggies for 14"??

Thanks a lot for the help. You can only build it first once, better do it right the first time. I have been piecing this truck together since I got it. After market parts are way over priced, especially the good ones.
