DPF Delete with stock exhaust

Anyone done a dpf/cat delete with stock exhaust? How does it sound like? What kind of mpg are you getting with it?

I ran the stock exhaust on mine for a few months while I was dealing with a vendor issue to get my tail pipe in. I dont think it changed much after I put on the different tail pipe.

As far as the mpg's I never have gotten the mile high claims some people post up.

The exhaust note will get deeper with a bigger exhaust, and it will have a more throaty sound at WOT.

I wasn't really impressed at all with the sound. Just sounded like a big hairdryer, like everyone says. Certainly better than with all of the junk on it, but not like a 351 with a MagnaFlow on the end... if you get my drift. I saw about 3-4 mpg better around town. Driving from MO to PA next month. I-70 all the way. Looking forward to some good numbers.

yes. doc also.. i am still tempted to do away with the muffler and bring the pipe out right in front of the rear tire, i always liked that for some reason. plus i realy cant swing the dough to finish the pipe out the back... not sure how or where to hang it from though... anyway, doc, yes. Did that and the spartan in february and an S&B cai a few weeks back. that changed the tone quite a bit too. More hairdryer... ok, no more hair dryer... jet engine? sounds more manly... delete pipe, tuner and intake is enough for me. only running the 250 tune. if anyone has any pics or ideas on how to bring the exhaust out in front of the rear wheel, lemme know.

The DPF/Cat delete pipes are what we sell the most of which bolt right into the stock exhaust. They will give a deeper/louder tone as well as some turbo whistle when you get on the throttle.

yes i did the dpf cat delete and it does sound like a hairdryer until you hammer the throttle then it sounds pretty throaty, as far as mpg goes im getting 19.5 with cruise set at 60mph, but hey anything is better than the 11.5 i was getting with that restrictive dpf!
