I've got almost 8000 miles on mine now and it does get quite a bit louder but it's still not loud enough for me. I had an '06 Dodge 2500 with a Cummins and it had a 5" MBRP turbo-back exhaust with no cats and a 6" tip so I'm used to loud. I'm not certain how the O2 sensors are set up on the 08's but if I can make it work I'm thinking about adding high flow cats soon to make it a bit louder. I just don't want any CEL's. I wish there was a video somewhere with high-flows installed with the ROR cat-back.

 

The rear O2s are mounted in the middle of the cats, you can get Magnaflow hi-flow cats installed and have the shop mount the O2 after the cat and not get a CEL.

& x2! Which one of you Roush boys is gonna do it?

 

If that's all that it takes I'll most likely do this very soon and get a sound clip up for all to hear. We've got a family owned fab shop so I can do all the O2 sensor relocating myself. Not to steal the thread but any idea which maggie cat I would need?

 

Here is all I have. My daughter is in the tailgate reflection.

 

Man those do sound good! Thanks

 

94306, 94006, or 94106 will all work.

306 is the most commonly used, and is finished in t-304 stainless, 12" long body.

006 is the same as 306 but T-409 stainless finish ( natural ) and a little less stuffed with filtering.

106 is the louder one of them all, 9" body, T-409 stainless.


And guys i'm sure most of you have seen them but dont forget Centerx49's exhaust videos, his videos are of rich high quality ( camcorder obviously ) and really capture the sweet sound of the Roush Off-Road. ( Especially if you have your home theatre system connected to your computer )
