MBRP Exhaust Qs

Hello Guys;

Some 500 miles ago I installed on our 2003 6.0 Ford Excursion one of those 4 " MBRP Exhausts from the turbo, keeping the OEM Cat, and with the MBRP muffler, at idle the truck sounds great, until 60mph the sound is very nice. However, anything over 65mph the sound is too loud for my taste, is there anything I can do to alleviate this?

Maybe add another small muffler? Any suggestions will be greatly appreciated.

I went with the Magnflow for that very reason. I assume the noise your are referring to is the drone. I went with the Magnaflow after reading several posts about the MBRP's tendencies to produce drone. Im not sure what else you could do to quiet the sound. I would definitely lose the cat no matter what I did.

There's no major problem with drone in the pick up trucks...the excursion is an "Ambient Sound Magnifier" so the vehicle is much more sensitive to exhaust drone.

MBRP does make an additional "mini muffler" called a resonator. I guess they are supposed to help people change the resonating frequency on their exhaust systems check this out: Part #: R1009UniversalResonator 4" Inlet /Outlet 12" Body 18" Overall, T304 MBRP Inc. Performance Exhaust - Diesel, Gas, and Muscle Car Exhaust Systems

hmm

I installed one on my Ex about 6 months ago and am happy with it but notice the drone also. My first thought was that the factory downpipe was insulated and the MBRP is not. It's primary function is for reducing heat transfer but thought it could make a difference on sound too. Thoughts???

Also what about all the joints. I got back under my truck to make sure all clamps are tight and they were but you can see small areas where the exhaust is leaking out (small black areas where the slit in the overlapping pipe is). What if I had the joints welded? Think that could make a difference?
