help SW header/turbo s exhaust

[swshon816]

I recently installed SW dual header and turbo s exhaust. I like the sound of it, but in the cabin it's extremely loud. When I put on gas it sounds like something vibrating really hard. I cant even talk with my wife sitting on passenger side. Is it normal? or Anyone knows how to decrease the noise? Please help me~

This is the exact setup I have. What type of exit did you go with? Dumped?

It's behind of rear tire.
You dont have crazy noise in the cabin?

Is it a SW exhaust system or did you just get the muffler and have a shop fab something up? My setup is loud but it's primarily because it's dumped under the cab. Depending on acceleration it'll make the cab vibrate.

It is just SW system. The headers, high flow converter and turbo s exhaust. Nothing is added on the system.

Weld the mufflers together if you do have it exiting out from the truck make sure it's out from under the truck.

Are the mufflers touching at all?

i dont think it is touching something, just the sound in the cab is too loud and annoying its like really loud drone under some acceleration.

if its normal. im ok with that, but im just curious if something wrong.

1. Did you use copper gasket rtv on all the slip fits?

2. Are the connections tight?

3. Are the mufflers installed the right direction? The S tube mufflers use a louvered core, so they cannot be installed both ways.

4. Are the tips out as far away from the cab as they can be?

If all of those things check out, it could just be normal. Drone is a very subjective term. The SW exhaust is an aggressive sounding system. Add the headers and You will hear it inside the cab. Drone, rattling, vibration, resonance, etc are undesirable but to be expected to some extent with an aggressive exhaust system. I would recommend installing a resonator if you're still unhappy with the amount of drone/resonance.
