Hello All! I am a new Chevy owner. Just traded my 05' Ford F350 Powerstroke for a 07' 2500HD CC 4x4 Dmax...loaded with every option.

I have been die hard Ford for many years, but this was just a logical choice. First impressions I can tell you that the Dmax is quiter, smoother, more powerful, warms up quicker, and has many, many more features for the money than Ford. I don't like the IFS front suspension, would rather have a solid front axle, and don't like the little tires! Otherwise, nice truck.

On to my question. Going to do exhuast first, no tuner. I wondered which MBRP system I should get, the turbo back or cat back? I had heard that a exhaust would cause error codes on the 07? Please provide me with first hand experience and suggestions.

Thank you all.

^thank you! your post and the post you quoted is quality information that I look forward to. Not just a one line response that doesn't answer anything. I have the exact feelings about an exhaust that you described. I do not want to make it a race truck. I do not want to worry about any warranty issues. I do not want to worry about passing inspection. I just want an improved sound and look. A cat-back exhaust is for me and I think I'm going with Silverline! You don't happen to know the cost of a 304 system, do ya?

I went thru the same thing as you. They test emissions in my county also. I went with the cat back 4" MBRP. I wouldn't waste the xtra $$ on the 304 unless you like going under your truck to polish it. The stainless 409 will outlive your truck. I'd save the money and throw it towards a Nicktane, Bilsteins or charity...

Either way shoot for a cat back and then add the cat delete pipe if you want it in the future. I will never do it because of the emission testing

Here is the link to my exhaust page. http://www.hdiesel.com/product.asp?id=15

The other vendors that posted have links in their signatures also. The vendors who take the time to answer your questions here are all good people.
