How bad is the interior drone?

[2500CTD]

@nightrider880 pretty bad at low RPM accelerating or towing, mostly anything under 1600. above that range is still pretty loud but sounds better.

How do you have your aero set up? Where did you mount the aero? Did you delete the cat, if you did did you just replace it with a regular 4" piece or buy an actual cat delete pipe?

[2500CTD]

mounted it where the stock muffler used to be, kitty ran away with a cat delete pipe which is offset and another offset pipe because the stock muffler is offset while the aero is straight thru. cut to length and had the 3 pieces welded together for $20 to install at home because having no cat is illegal...

[2500CTD]

I love texas! You can do whatever the hell you want to your diesel pickup and it will pass inspection. I go thru town all the time with my straight exhaust blowin coal all over the place and the cops just stare. Also nice vid man.

The 4040XL is such a cool sounding muffler, normally only I drive my truck, but once in a while when my other driver has to use it, I will hear a cool sound, think, wow that rig sounds great, and then, hey! thats MY truck! It sounds great from outside, especially with a load!

just how its always been, it'll smoke a little then clear right up once the turbo spools. really is all stock.
