I've had it on for two weeks. Does anyone else have this exhaust? There is a resonance that comes thru that is extremely annoying.

I've learned to eliminate the resonance by switching to tow haul.

Does switching to tow haul turn off the MDS system?

Thanks

 

im confused the mds system isnt the cause of the resonance from the muffler. if anything when it kicks into mds, the exhaust should quiet down some for it is now only using 4 cyl. its just the opposite putting in tow/haul od off mode in my truck, it resonates more because it doesnt shift into higher gears so it stays in lower gears at higher rpms making the exhaust tone level off when at a constant speed. but i got exhaust because i wanted it to be loud and turn heads..

 

Don't get me wrong, It sounds good until it kicks into MDS between 35-50. It is when you first start off there is a sound that the local shop can't figure out. They feel that since it is a straight thru stainless system that the resonance is in the engine resonated thru the system.They also think that once the system gets coated with soot that it will go away. The MDSdoesn't bother me at all at highway speeds. Just the first three shifts

The tow haul just keeps the sound in the sweet spot until I what to conserve.
