MBRP cat back exhaust

Recommended Posts

Big Red a 4" inch exhaust system from.MBRP.

Took me awhile to remove the old setup and ended up using my saw zaw to cut a portion of it. I was worried the weight would damage the brake line and wiring harness.

Need a saw zaw for the new system too.

I got it all installed. Tightened all the band clamps, no leaks and installed the 4" matte black exhaust tip.

Was able to just crawl around underneath without putting it on ramps.

A jack and a piece of 2x6 to fangle the new system up in place helped.

Truck sounds great! Not too loud. Can definitely hear it in the cab. May need some tweaks later on.

Towing my big camper could be interesting!

Almost two months in now.  Still love it!  Still sounds great.  No issues with the bands loosening up so far.  Cannot hear any leaks coming from underneath.


Wind the truck up over 2500rpm and it sounds real good; like a big truck is suppose to sound.

Just got my MBRP installed last night.  Sounds SO MUCH better, glad to hear you are still liking it after a few months.  Couldn't really get into the throttle when I finished since it was the middle of the night and the houses in my neighborhood are close together but excited to take it for a drive today.
