Straight Piped D-Max

I just straight piped my D-Max and it sounds like a totally different truck. It sounds so good when ever I stomp on it and its def a head turner now. I should have done this a long time ago. I would recomend this to anyone who like to get others attention!

Will this help with mileage? Or would a 4" or 5" exhaust be more beneficial?

I don't know if it helps on mileage, but I love the sound of it! You know when it's a Duramax coming down the road! :cool

When you strait pipe your truck it is hard to keep your foot out of it for about 3 monthes. After that your MPG might go up a little. It is very hard for me to keep my foot out of the truck unless I am on a long trip. A 4 or 5 inch exhaust will lower your EGT's over a stock pipe strait piped. You may see about a 1/2 or 1 MPG more with either stock or 4 or 5 inch pipe.

Hoov just buy a cheap turbo back kit. I still have my stock exhaust. I can swap my exhaust out in about 1 hour.
