Muffler delete on crd?

Hey guys, I was gonna do a dpf delete this spring and, since the crd has no sound at all, I was thinking I could do a muffler delete at the same time... Ģi was wondering if anyone had tried it and the pros and cons! I want to hear that little engine a little more but I don't want drones or annoying sound levels... just enough to drown the duratracs!!!

You will get a tad bit more noise (and much more turbo) with a DPF delete (as I noticed).
It really not any louder but you can pick up more of what's going on .. sounds "clearer".
Have you tuned your's yet ? That's the most fun ...
I would start with the DPF delete and see where that goes. You don't have to do any "cutting" for that anyways so it's relatively easy.

I have contemplated taking the muffler off but I think there may more of an increase in resonance.
It isn't much of a muffler there now anyways, more of a resonator.

What did you use as replacement pipe? I think I briefly looked at the resonator on mine, and it looked like I'd need to do a bend from where I'd have to cut it off?

no real drone that i notice but i have a loud sound system haha and i actually like abit of drone


used a 3" SS pipe i believe, cut the reso right at the back and slid the straight pipe over and welded it
a 45 degree cut seems to follow the body lines perfectly

I have the 3 inch MBRP exhaust , it's just straight 3 inch from the DPF back. Really not much louder than stock, no idea how loud it will be with the DPF removed.

i was gonna go for the 4" dpf back but didnt see the point, stock is 2.75" and if i were gonna do it, it would only make sense to do turbo back

If your doing the DPF delete might as well get rid of that "muffler" to. Like someone already said its more of a resonator anyways. I removed it before my DPF delete and it didnt change the sound at all ha. With the DPF gone now I love it. Got them to weld a piece of pipe in and then a black tip. No drone at all but it sounds nice when you hammer on it. I am still contemplating the turbo resonator delete as well...

How long do our DPF last before getting plugged up and needing replacement?

Im still not sure how the DPF delete works. What do I need to to a DPF delete? Will most muffler shops cut the old one out and replace with straight pipe?

The dpf is flanged and bolted in. So you can either get a pipe built that you can bolt in or you can get an exhaust shop to weld in a pipe but then you wouldn't be able to put the dpf back in if needed. CB engineering makes nice bolt in pipes, that is what I have. And then you will need a tune to tune out the dpf(I have the GDE tune with dpf delete)
