This is my first CTD.2007 5.9 A/T,4.10 Bone stock.Would like to delete muffler or install a straight thru muffler while keeping stock pipes.Will this mod cause a trouble code to be thrown.Where is the best place to buy muffler delete?

 

No codes. Buy one from Lary here at the DTR store. You'll get a discount for being a member. Make sure you call him to get your discount.

 

I just installed mine from Genos and the sounds is great. It is loud under throttle but at speed it quiets back down to stock.

 

They seem to give it a good tone, and fairly quiet at cruise speeds

 

I love mine. Got it from RPMOutlet.com. It's a bit short but it works fine. The sound is great...

 

I like mine as well. I've got a new rattle that just started yesterday I need to chase though. I suspect one of the band clamps or the hangar is loose.

 

how does the truck sound while towing with the delete? Any drone at highway speeds?

 

Mine sounded good for the first couple days. Then I put my 26ft toy hauler behind her. HAHA, I unhooked and had the muffler put back in........

 

To loud for ya??

 

I haven't towed yet. I know the alignment and hangar positioning made a huge difference in the amount of drone. Now there is only a slight drone at 1400-1500 rfp.

 

I towed my trailer about 5000 miles this summer with no drone at all. I still have the CAT in place though.

 

I swapped my muffler for a magnaflow direct fit muffler. It is a stainless steel 4" straight thru muffler that uses the stock hangers. It is just a bit louder and it really seems to bring down the EGTs when towing. $250 well spent.

 

Be careful, I went for an inspection in Austin(yeah I know)TX, two days ago and DPS is now making inspectors check for a cat AND a muffler. This inspection shop will fail a diesel if there is no muffler, I couldn't believe it, but that's what I was told by the shop owner. He said that DPS is cracking down on modified diesels, we'll see!

 

doesn't this mod matter if you have QC vs. Mega?

 

I'm pretty sure the turbo counts as a sound dampening devise...
