JUST PURCHASED THE MBRP 4" CAT BAK WAS WONDERING IF THIS WAS A GOOD SYSTEM FOR MY TRUCK AND IF I WILL B PLZD WITH THE PERFORMANCE FOR MY 2007 MEGA CAB DUALLY RAM 3500 5.9L I DO A LOT OF TOWING USING BUMPER PULL TRAILERS AND GOOSENECKS WITH ABOUT 10,OOO LBS ON AVERAGE. I WENT WITH THE 4" CUZ I HEARD THAT WITH THE 5" I WUD LOOZ LOW END TORGUE AND AT HWY SPEEDS I WUD GET A DROWN SOUND IN THE CAB. DID I DO OK

 

I have the mbrp 4" duals turpo back and love them. They have a great sound to them and perform great. After i installed them i notice better mpg and throttle response. I think you made a good pick.

 

YEA U DID A GR8 JOB. U WONT HEER DROWN SOUND IN CAB OR LOOZE torgue. U WILL B PLZD.

 

Kinda late to wonder about it, you already bought it!

 

thnx 4 all the input feel btr bout my decision.
